2. Programming with bootloader
step 1 – Connecting PIC32MX7
For programming, microcontroller use bootloader program which
is preinstaled in to MCU memory. To transfer .hex file from a PC to
MCU you need bootloader software (mikroBootloader USB HID)
which can be downloaded from:
http://www.mikroe.com/eng/products/view/573/

programmer. The mikroProg programmer is connected to the
development system via the CN10 connector, Figure 3-1.
Figure 3-1: Connecting
mikroProg programmer
In order to connect the
mikroProg programmer to
the development system, it is
necessary to place IDC10 connector
on 2x5 male header CN10. Make sure
that knob on IDC10 connector must be
oriented towards mark MIKROPROG, Figure 3-1.

mikroProg features:
01 Fast mikroICD In-Circuit Debugger
02 Support for over 600 PIC, dsPIC and PIC32 devices
03 Compatible with mikroC, mikroBasic and mikroPascal
compilers for PIC, dsPIC and PIC32
04 Elegant minimalistic design, clean matte white plastic
finish and color indicator LEDs
Page 15
4. Programing with
ICD3 programmer
The microcontroller can be also programmed with
ICD3 programmer. This programmer is connected to
PIC32MX7 board via on-board ICD connector CN5.
Figure 4-1: Connecting
ICD3 programmer
In order to make connection between ICD3 programmer and PIC32MX7
place programmers cable in to ICD connector CN5, Figure 4-1. To use
ICD3 programmer it is necessary to instal program MPLAB on a PC.

5. Touch Screen
The development system features a TFT
320x240 display covered with a resistive
touch panel. Together they form a
functional unit called a touch screen.
It enables data to be entered and
displayed at the same time. The
way of entering and displaying data
depends on the program loaded into
the microcontroller. The TFT display
is capable of showing data in
262.000 diffe­rent colors.

6. Temperature sensor
Figure 6-1:
MCP9700A
The built in temperature sensor (MCP9700A) is capable for measuring
temperature in range between -40 and +125°C with accuracy of +/-2°C.
Temperature sensor is attached to MCU via pin RB8 (TEMP).

7. Flash Memory
Figure 7-1: Flash memory module
Since multimedia applications are getting increasingly demanding, it is
necessary to provide additional memory space to be used for storing programs
by the microcontroller. The flash memory module enables the microcontroller to
use additional 8Mbit flash memory. It is connected to the microcontroller via the
Serial Peripheral Interface (SPI).

8. EEPROM Memory
Figure 8-1: EEPROM memory module
EEPROM (Electrically Erasable Programmable Read-Only Memory) is a built-in
memory module used for storing data that should be saved when power goes
off. The 24AA01 circuit may store 1Kbit data and uses serial I2C communication
to exchange data with the microcontroller.

There is a built-in MMC/SD slot for MMC/SD card provided on the development system. It
enables the system to additionally expand available memory space. The Serial Peripheral
Interface (SPI) is used for communication between the microcontroller and MMC/SD card.

10. Audio Module
The Multimedia Board features an
audio module providing an interface for
a microphone and stereo headphones. This
module enables audio recording via a mono
microphone. The microphone is connected to
the system via a 3.5mm connector CN7. Stereo
Figure 10-1: Inserting
3.5mm headphones jack
headphones are used for audio reproduction. They are
connected to the system via a 3.5mm connector CN6. For
the proper use of microphone and headphones, it is necessary
to write a program and load it into the microcontroller. In
addition to the audio recording and reproduction, the audio module
can also generate a side tone in the headphones. Volume as well as
other functions of this module are controlled by the microcontroller
from within the software using serial I2C communication. Communication
between the audio module and the microcontroller is performed via the Serial
Peripheral Interface (SPI).

13. Indication LEDs
An LED (Light-Emitting Diode) is a highly efficient electronic
source of light. When connecting LEDs, it is necessary to use
a current limiting resistor. A common LED diode voltage is
approximately 2.5V, while the current varies from 1 to 20mA
depending on the type of LED. The Multimedia Board uses LEDs
with current I=1mA.

16. Accelerometer
Figure 16-1: Accelerometer
The accelerometer is used to measure acceleration, orientation, gravity, etc.
The accelerometer’s function is defined by the user in the program loaded
into the microcontroller. Communication between the accelerometer and the
microcontroller is performed via the SPI interface.
