introduction
Introduction
ARM® Cortex™-M3 and Cortex™-M4 are increasingly popular
microcontrollers. They are rich with modules, with high performance and
low power consumption, so creating a development board the size of
EasyMx PRO™ v7 for STM32 was really a challenge. We wanted to put
as many peripherals on the board as possible, to cover many internal
modules. We have gone through a process of fine tuning the
board's performance, and used 4-layer PCB to achieve maximum
efficiency. Finally, it had met all of our expectations, and even
exceeded in some. We present you the board which is powerful,
well organized, with on-board programmer and debugger and
is ready to be your strong ally in development.

power supply
Power supply
Board contains switching power
supply that creates stable voltage
and current levels necessary
for powering each part of
the board. Power supply
section contains specialized
MC33269DT3.3 power regulator
which creates VCC-3.3V power supply,
thus making the board capable of supporting
3.3V microcontrollers. Power supply unit can be
powered in three different ways: with USB power supply
(CN20), using external adapters via adapter connector (CN30)
or additional screw terminals (CN31). External adapter voltage levels
must be in range of 9-32V DC and 7-23V AC. Use jumper J9 to specify
which power source you are using. Upon providing the power using either external
adapters or USB power source you can turn on power supply by using SWITCH 1 (Figure
3-1). Power LED ON (Green) will indicate the presence of power supply.

25MHz crystal oscillator. We carefully chose the most convenient crystal
value that provides clock frequency which can be used directly, or with the PLL
multipliers to create higher MCU clock value. MCU card also contains 32.768 kHz
crystal oscillator which provides external clock for RTCC module.
3
USB communications lines. These two jumpers, when in USB position,
connect D+ and D- lines of the on-board USB connector with PA11 and PA12
microcontroller pins. Since STM32F107VCT6 supports USB, jumpers are in USB
position.

With STM32 Cortex™-M3 and Cortex™-M4 microcontrollers you have the
ability to select specific boot space (User flash memory, system memory
or embedded SRAM), depending on the boot pins value (BT0, PB2). Boot
pins are set to ground (0) through 100K resistors. In order to set BT0 and
PB2 pins to VCC (1), you must push SW11.1 and SW11.2 DIP switches to
ON position, Figure 4-2. The values on the BOOT pins are latched on the
fourth rising edge of system clock after a reset.

How to properly place your MCU card into the socket?
Before you plug the microcontroller card into the
socket, make sure that the power supply is turned
off. Images below show how to correctly plug the
card. First make sure that MCU card orientation
matches the silkscreen outline on the EasyMx

Figure 4-3: On-board MCU
socket has silkscreen
markings which will help
you to correctly orient the
MCU card before inserting.
page 10
PRO™ v7 STM32 board MCU socket. Place the
MCU card over the socket, so each male header is
properly aligned with the female socket, as shown
in Figure 4-4. Then put the MCU card slowly down
until all the pins match the socket. Check again if

everything is placed correctly and press the MCU
card until it is completely plugged into the socket
as shown in Figure 4-5. If done correctly, all pins
should be fully inserted. Only now you can turn on
the power supply.

Hardware Debugger
What is Debugging?
Every developer comes to a point where he has to monitor the
code execution in order to find errors in the code, or simply
to see if everything is going as planed. This hunt for bugs,
or errors in the code is called debugging. There are two ways
to do this: one is the software simulation, which enables
you to simulate what is supposed to be happening on the
microcontroller as your code lines are executed, and the other,
most reliable one, is monitoring the code execution on the
chip itself. And this latter one is called hardware debugging.
"hardware" means that it is the real deal - code executes right on
the target device.
How do I use the debugger?
When you build your project for debugging, and program the microcontroller with this HEX file, you can
start the debugger using [F9] command. Compiler will change layout to debugging view, and a blue line
will mark where code execution is currently paused. Use debugging toolbar in the Watch Window
to guide the program execution, and stop anytime. Add the desired variables to Watch Window and
monitor their values.
What is hardware debugger?
The on-board mikroProg™ programmer supports hardware
debugger - a highly effective tool for a Real-Time debugging
on hardware level. The debugger enables you to execute your
program on the host STM32 microcontroller and view variable
values, Special Function Registers (SFR), RAM, CODE and EEPROM
memory along with the code execution on hardware. Whether you
are a beginner, or a professional, this powerful tool, with intuitive
interface and convenient set of commands will enable you to track
down bugs quickly. mikroProg debugger is one of the fastest, and
most reliable debugging tools on the market.
Supported Compilers
All MikroElektronika compilers, mikroC™, mikroBasic™ and
mikroPascal™ for ARM® natively support mikroProg™ for STM32,
as well as other compilers, including KEIL®, IAR®. Specialized
DLL module allows compilers to exploit the full potential of fast
hardware debugging. Along with compilers, make sure to install
the appropriate programmer drivers and mikroProg Suite™
for ARM® programming software, as described on pages 14
and 15.

EasyMx PROv7
Here is a short overview of which debugging commands are supported in mikroElektronika compilers. You can see what each command does,
and what are their shortcuts when you are in debugging mode. It will give you some general picture of what your debugger can do.

Input/Output Group
One of the most distinctive features of EasyMx PRO™
v7 for STM32 are it’s Input/Output PORT groups. They
add so much to the connectivity potential of the board.
Everything is grouped together
PORT headers, PORT buttons and PORT LEDs are next to each other, and
Figure 6-1: I/O group contains PORT header, tri-state pull
grouped together. It makes development easier, and the entire EasyMx PRO™ v7
up/down DIP switch, buttons and LEDs all in one place
for STM32 cleaner and well organized. We have also provided an additional PORT
headers on the right side of the board, so you can access any pin you want from that side of the board too.

Tri-state DIP switches, like SW1 on Figure 6-3, are used to enable 4K7
pull-up or pull-down resistor on any desired port pin.
Each of these switches has three states:
1. middle position disables both pull-up and pull-down
feature from the PORT pin
2. up position connects the resistor in pull-up state to
the selected pin
3. down position connects the resistor in pull-down

0.2mA to 20mA, depending on the type of the LED and
the manufacturer. The EasyMx PRO™ v7 for STM32 board
uses low-current LEDs with typical current consumption
of 0.2mA or 0.3mA. Board
contains 67 LEDs which can
be used for visual indication
of the logic state on PORT
pins. An active LED indicates
that a logic high (1) is present
on the pin. In order to enable
PORT LEDs, it is necessary
to enable the corresponding

Figure 6-5: Button press
DIP switch SW10 is
level DIP switch (tri-state)
available for selecting
which logic state will be applied to corresponding MCU
pin when button is pressed, for each I/O port separately.
If you, for example, place SW10.1 in VCC position, then
pressing of any push button in PORTA/H I/O group will
apply logic one to the appropriate microcontroller pin.
The same goes for GND. If DIP switch is in the middle
position neither of two logic states will be applied to
the appropriate microcontroller pin. You can disable pin
protection 220ohm resistors by placing jumpers J6 and
J7, which will connect your push buttons directly to VCC
or GND. Be aware that doing so you may accidentally
damage MCU in case of wrong usage.

connectivity
mikroBUS sockets
™
Easier connectivity and simple configuration
are imperative in modern electronic devices.
Success of the USB standard comes from it’s
simplicity of usage and high and reliable data
transfer rates. As we in mikroElektronika see it,
Plug-and-Play devices with minimum settings
are the future in embedded world too. This is
why our engineers have come up with a simple,
but brilliant pinout with lines that most of
today’s accessory boards require, which almost
completely eliminates the need of additional
hardware settings. We called this new standard
the mikroBUS™. EasyMx PRO™ v7 for STM32
supports mikroBUS™ with two on-board
sockets. As you can see, there are no additional
DIP switches, or jumper selections. Everything
is already routed to the most appropriate pins
of the microcontroller sockets.
mikroBUS™ host connector
Each mikroBUS™ host connector consists of two
1x8 female headers containing pins that are
most likely to be used in the target accessory
board. There are three groups of communication
pins: SPI, UART and I2C communication. There
are also single pins for PWM, Interrupt,
Analog input, Reset and Chip Select. Pinout
contains two power groups: +5V and GND on
one header and +3.3V and GND on the other
1x8 header.

The UART (universal asynchronous receiver/trans­
mitter) is one of the most common ways of exchanging
data between the MCU and peripheral components. It is a serial
protocol with separate transmit and receive lines, and can be used for
full-duplex communication. Both sides must be initialized with the
same baud rate, otherwise the data will not be received correctly.
Enabling USB-UART A
Modern PC computers, laptops and notebooks are no longer
equipped with RS-232 connectors and UART controllers. They
are nowadays replaced with USB connectors and USB
controllers. Still, certain technology enables UART

Ethernet is a popular computer networ­king
technology for local area networks (LAN).
Systems communicating over Ethernet
divide a stream of data into individual
packets called frames. Each frame contains
source and destination addresses and
error-checking data so that damaged
data can be detected and re-transmitted.
EasyMx PRO™ v7 for STM32 features
standard RJ-45 connector which enables
microcontrollers that support Ethernet
communication to establish a connection
with a computer, router or other devices.
All four Ethernet lines (TPOUT+, TPOUT-,
TPIN+ and TPIN-) are routed directly to the
MCU card socket and cannot be accessed
via PORT headers. Additional signalization
LEDs (green and yellow) are provided on
the Board next to RJ-45 connector.

Controller Area Network (CAN or CAN
bus) is a vehicle bus standard designed
to allow microcontrollers and devices to
communicate with each other within a
vehicle without a host computer. CAN
is a message-based protocol, designed
specifically for automotive applications
but now also used in other areas such
as industrial automation and medical
equipment. EasyMx PRO™ v7 for STM32
is equipped with SN65HVD230 – a 3.3V
CAN Transceiver and a pair of screw
terminals which provide microcontrollers
with integrated CAN controller with the
necessary physical interface for CAN
communication. Make sure to correctly
connect negative and positive differential
communication lines before using this
module.

multimedia
Audio I/O
It's hard to imagine modern multimedia devices without high quality audio reproduction
modules. Sounds and music are almost as important as graphical user interfaces.
Along with other multimedia modules, EasyMx PRO™ v7 for STM32 contains high
end stereo VS1053 audio codec. It features Ogg Vorbis/MP3/AAC/WMA/FLAC/
WAV/MIDI audio decoder, as well as an PCM/IMA ADPCM/Ogg Vorbis encoder on a
single chip. Board also contains two stereo audio connectors for interfacing with
standard 3.5mm stereo audio jacks. VS1053 receives the input bit stream through a
serial input bus, which it listens to as a system slave. The input stream is decoded and
passed through a digital volume control to an 18-bit oversampling, multi-bit, sigma-delta
Digital to Analog Converter (DAC). The
decoding is controlled via a serial control
bus. In addition to the basic decoding,
it is possible to add application specific
features like DSP effects to the user RAM
memory. You can build music players,

Navigation switch
When working with multi­media
applications it is far more intuitive
to use a single joystick than several
different push buttons that are more
far apart. This is more natural for
users and they can browse through
on-screen menus, or even play games
much easier. EasyMx PRO™ v7 for STM32
features navigation switch with five different
positions: Up, Down, Left, Right and Center.
Each of those acts as a button, and is connected
to one of the following microcontroller pins: PD4,
PB5, PD2, PA6, PC13 (respectively). Before using the
navigation switch, it is necessary to pull-up mentioned
microcontroller pins using tri-state DIP switches located in I/O
groups. After pressing the navigation switch in desired direction,
associated microcontroller pins are connected to GND, which can be
detected in user software.

DS1820 - Digital
Temperature Sensor
DS1820 is a digital temperature
sensor that uses 1-wire®
interface for it’s operation. It is
capable of measuring temperatures
within the range of -55 to 128°C,
and provides ±0.5°C accuracy for
temperatures within the range of -10 to
85°C. It requires 3V to 5.5V power supply
for stable operation. It takes maximum
of 750ms for the DS1820 to calculate
temperaturewith9-bitresolution.1-wire®
serial communication enables data to be
transferred over a single communication
line, while the process itself is under the
control of the master microcontroller.
The advantage of such communication is
that only one microcontroller pin is used.
Multiple sensors can be connected on the
same line. All slave devices by default
have a unique ID code, which enables
the master device to easily identify all
devices sharing the same interface.
Board provides a separate socket (TS1)
for the DS1820. Communication line with
the microcontroller is established using
SW14.5 or SW14.6 DIP switch (ON
position).

The LM35 is a low-cost precision
integrated-circuit temperature sensor,
whose output voltage is linearly
proportional to the Celsius (Centigrade)
temperature. The LM35 thus has an
advantage over linear temperature
sensors calibrated in ° Kelvin, as the
user is not required to subtract a large
constant voltage from its output to
obtain convenient Centigrade scaling.
It has a linear +10.0 mV/°C scale factor
and less than 60 μA current drain. As it
draws only 60 μA from its supply, it has
very low self-heating, less than 0.1°C
in still air. EasyMx PRO™ v7 for STM32

Serial Flash Memory
Flash memory is a non-volatile storage chip that
can be electrically erased and reprogrammed. It
was developed from EEPROM (electrically erasable
programmable read-only memory) and must be
erased in fairly large blocks before these can be
rewritten with new data. The high density NAND
type must also be programmed and read in (smaller)
blocks, or pages, while the NOR type allows a single
machine word (byte) to be written or read independently.
Flash memories come in different sizes and supporting
different clock speeds. They are mostly used for mass
storage, as in USB Flash Drives, which are very popular today.
Enabling Serial Flash
EasyMx PRO™ v7 features M25P80 Serial Flash Memory which uses
SPI communication interface and has 8 Mbits of available memory,
organized as 16 sectors, each containing 256 pages. Each page is 256 bytes
wide. Thus, the whole memory can be viewed as consisting of 4096 pages, or
1,048,576 bytes. Maximum clock frequency for READ instructions is 40MHz.
In order to connect Serial Flash Memory
to the microcontroller you must enable
SW13.1, SW13.2, SW13.3 and SW13.8
switches. This connects SPI lines to MCU_
MOSI, MCU_MISO, MCU_SCK and PD7 (CS)
microcontroller pins.
What is SPI?
The Serial Peripheral Interface Bus or SPI bus is a synchronous serial data link standard that operates in full
duplex mode. It consists of four lines MISO (Master Input Slave Output), MOSI (Master Output Slave Input), SCK
(Clock) and CS (Chip Select). Devices communicate in master/slave mode where the master device initiates the
data frame. Multiple slave devices are allowed with individual slave select (chip select) lines.

EEPROM is short for Electrically Erasable
Programmable Read Only Memory. It is usually
a secondary storage memory in devices containing
data that is retained even if the device looses power
supply. Because of the ability to alter single bytes
of data, EEPROM devices are used to store personal
preference and configuration data in a wide spectrum
of consumer, automotive, telecommunication, medical,
industrial, and PC applications.
EasyMx PRO™ v7 for STM32 supports serial EEPROM which
uses I2C communication interface and has 1024 bytes of
available memory. EEPROM itself supports single byte or 16-byte
(page) write and read operations. Data rates are dependent of power
supply voltage, and go up to 400 kHz for 3.3V power supply.
What is I2C?
I2C is a multi-master serial single-ended bus that is used to attach low-speed peripherals to computer or embedded
systems. I²C uses only two open-drain lines, Serial Data Line (SDA) and Serial Clock (SCL), pulled up with
resistors. SCL line is driven by a master, while SDA is used as bidirectional line either by master or slave device.
Up to 112 slave devices can be connected to the same bus. Each slave must have a unique address.

ADC inputs
Digital signals have two discrete states, which are decoded as high
and low, and interpreted as logic 1 and logic 0. Analog signals,
on the other hand, are continuous, and can have any value
within defined range. A/D converters are specialized circuits
which can convert analog signals (voltages) into a digital
representation, usually in form of an integer number.
The value of this number is linearly dependent on
the input voltage value. Most microcontrollers
nowadays internally have A/D converters
connected to one or more input pins. Some
of the most important parameters of
A/D converters are conversion time
and resolution. Conversion time

from GND to VCC.
Resolution represents the number of
discrete steps that supported voltage range
can be divided into. It determines the sensitivity of the A/D converter. Resolution is represented in maximum
number of bits that resulting number occupies. Most microcontrollers have 10-bit resolution, meaning that maximum
value of conversion can be represented with 10 bits, which converted to integer is 210=1024. This means that supported voltage
range, for example from 0-1.8V, can be divided into 1024 discrete steps of about 1.758mV. EasyMx PRO™ v7 for STM32 provides an
interface in form of potentiometer for simulating analog input voltages that can be routed to any of the 5 supported analog input pins.

Piezo electricity is the charge which accumulates in
certain solid materials in response to mechanical pressure,
but also providing the charge to the piezo electric material
causes it to physically deform. One of the most widely
used applications of piezo electricity is the production of
sound generators, called piezo buzzers. Piezo buzzer is an
electric component that comes in different shapes and sizes,
which can be used to create sound waves when provided
with analog electrical signal. EasyMx PRO™ v7 for STM32
comes with piezo buzzer which can be connected to PE14
microcontroller pin. Connection is established using SW14.8
DIP switch. Buzzer is driven by transistor Q1 (Figure 25-1).
Microcontrollers can create sound by generating a PWM
(Pulse Width Modulated) signal – a square wave signal,
which is nothing more than a sequence of logic zeros and
other modules
Piezo Buzzer
ones. Frequency of the square signal determines
the pitch of the generated sound, and duty cycle of
the signal can be used to increase or decrease the
volume in the range from 0% to 100% of the duty
cycle. You can generate PWM signal using hardware
capture-compare module, which is usually available in
most microcontrollers, or by writing a custom software
which emulates the desired signal waveform.
Supported sound frequencies
Piezo buzzer’s resonant frequency (where you can expect
it's best performance) is 3.8kHz, but you can also use it to
create sound in the range between 2kHz and 4kHz.

In order to use the on-board Piezo Buzzer in
your application, you first have to connect the
transistor driver of piezo buzzer to the appropriate
microcontroller pin. This is done using SW14.8 DIP
switch which connects it to PE14 pin.
