DEVELOPMENT
BOARD
INTRODUCTION
The LV18FJ development system is a full-featured development board for Microchip’s low
voltage microcontrollers. It is designed to allow students and engineers to easily test and
explore the capabilities of low-voltage microcontrollers. It also allows low-voltage microcontrollers to be interfaced with external circuits and a broad range of peripheral devices,
making it possible for the user to concentrate on software development.
Figure 1 illustrates the development board. There are identification marks beside each component on a silkscreen. These marks describe connections to the microcontroller, operation
modes and provide additional information. Since all relevant information is provided on the
board there is almost no need for additional schematics.

SWITCHES
The LV18FJ development board features a number of peripherial devices. In order to enable
them before programming, the appropriate jumpers or switches have to be properly set.
Switches are devices that have two positions - ON and OFF, which having the role to establish or break connection between two contacts. The LV18FJ development board has three
groups of switches.
The first group, SW1, is used to enable SPI communication for interfacing with MMC/SD
multimedia card. It is also used for RS-232 communication.
Switches of the SW2 are used to enable LEDs connected to ports. For example, if the switch
enabling PORTB is OFF, all PORTB LEDs will be turned off.
Switches of the SW3, SW4 and SW5 are used for controlling output port pins by
enabling/disabling them.

JUMPERS
Jumpers, like switches, can break or establish connection between two points. Under the
plastic cover of a jumper there is a conductive contact which establishes connection when
the jumper is placed over two pins.
For example, the jumpers J9 and J10 are used to connect or disconnect ethernet leds to the
RA0 and RA1 pins, respectively. In order to establish a connection, the jumper should be
placed over two contacts.
Jumper is ON
Jumper is OFF
Figure 3.
Jumper as a switch
Jumpers are commonly used as selectors between two possible connections via three pin
connector. As illustrated in Figure 4, the connector in the middle can be connected to the left
or right pin, depending on the jumper’s position.

Microcontroller’s pins are routed to various peripherals as illustrated in Figure7. All ports
are directly connected to Direct Port Access connectors. Such connectors are normally used
for connecting external peripherals to the board or for providing digital logic probes for testing and measuring.
All ports are connected to LEDs, push-button switches and pull-up/down resistors, which
allow easy monitoring and testing of digital pin state .
Some pins are connected to other peripherials such as DS1820 temperature sensor, RS-232
communication, 7-segment displays, LCD etc.

POWER SUPPLY
LV18FJ has two kinds of power supply- regulated supply from the USB cable (default) or
external power supply. In case of the USB power supply, the system should be connected to
PC using the USB programming cable, while the power supply selection switch should be
set in the right-hand position.
In case of the external power supply, the LV18FJ board produces +5V using an LM7805
voltage regulator. The external power supply can be AC or DC. Power supply voltage can
be in the range of 8-16V and the power supply selection switch should be set in the lefthand position. Figure 8 illustrates USB and external power supply connectors.

mikroICD (IN CIRCUIT DEBUGGER)
mikroICD is a highly effective tool for Real-Time debugging on hardware level. The
mikroICD debugger enables you to execute a program on the LvPIC microcontroller and
view variable values, Special Function Registers (SFR) and EEPROM while the program is
running.
mikroICD can be used within any of MikroElektronika’s compilers for LvPIC (mikroC,
mikroBasic or mikroPascal). You just have to select the appropriate build type (Release or
ICD Debug), build the project, program the MCU, select the appropriate debugger
(mikroICD Debugger) and that’s all.
The mikroICD debugger uses the PICFlash programmer to communicate with the compiler and supports common debugger commands:
Start Debugger
Run/ Pause Debugger
Toggle Breakpoint
Run to cursor
Step Into
Step Over
Flush RAM
Stop Debugger

The connection between buttons and PORTA, PORTB, PORTC and PORTD is shown in
Figure 19. Jumper J1 determines whether a button press will bring logic zero or logic one to
the appropriate pin.
When button is released, pin state is determined by the pull-up or pull-down port jumpers.
In the example shown in Figure 19, J1 is connected to +5V, therefore a button press will
bring logic one to the appropriate pins.

LCD 2X16 IN 4-BIT MODE
A standard character LCD is probably the most widely used data visualization component.
Usually, it can display two lines of 16 alphanumeric characters, each made up of 5x8 pixels. The character LCD communicates with the microcontroller via a 4 bits. The connection
to the microcontroller is shown in Figure 25. where there are only four data lines. It is
important to know that the LCD should be placed or removed from LV18FJ board only after
the power is turned off.

RS232 RS-232 COMMUNICATION
ENABLED
RS-232 communication enables point-to-point data transfer. It is commonly used in data
acquisition applications, for the transfer of data between the microcontroller and PC. Since
the voltage levels of the microcontroller and PC are not directly compatible with each other,
a level transition buffer such as the MAX232 must be used.
Figure 26. RS232 connectors
In order to provide a more flexible system, the microcontroller is connected to the MAX232
through switches on the SW1. In order to use it, switches 1 and 2 or 3 and 4 on the SW1
must be enabled. Both RS232 modules can be used at the same time.

Ethernet
SUPPORTED
Ethernet is the most common Local Area Network (LAN) technology in use today.On the
top of the physical layer, Ethernet stations mutually communicate by sending data packets
to each other. Each Ethernet station is assigned a single 48-bit MAC address used to specify both the destination and the source of each data packet.
Figure 28. Serial Ethernet
Note: Make sure to select the proper voltage level depending on the MCU Card attached to
the LV18FJ development board.
Improper voltage level can damage development system or Serial Ethernet chip!
Note: Both jumpers J9 and J10 must be connected.

DS1820 DIGITAL THERMOMETER
DS1820 digital thermometer is convenient for environmental temperature measurement, having the temperature in the range of -55°C to 125°C with +/-0.5°C
accuracy. It must be properly placed in the 3-pin socket provided on LV18FJ, with its rounded side to the
right edge of the board (see Fig. 30) otherwise the
DS1820 could be permanently damaged. DS1820’s
data pin can be connected to either RD0 or RD1 pin,
which is determined by the jumper J2.

All microcontroller input/output pins can be accessed via connectors placed along the right
side of the board. For each PORT there is one 10-pin connector providing VCC, GND and
eight port pins.
Figure 34.
Direct port access
connectors
These connectors can be used for system expansion with external boards such as Serial
Ethernet, Compact Flash, MMC/SD, ADC, DAC, CAN, RTC, RS-485 etc. Ensure that onboard peripherals are disconnected from the microcontroller when an external peripheral is
attached to the board. The appropriate jumpers and switches must be set for this purpose.
The connectors can also be used for attaching logic probes or test equipment.

SUPPORTED
MMC/SD card is used as a storage media for a portable device, in a form that can be easily
accessed by PC. For example, a digital camera uses MMC/CD card to store image files.
Microcontroller on the LV18FJ development board comunicates with MMC/SD via SPI
communication. The on-board connector enables users to easily access MMC/SD card from
the microcontroller.
Figure 37. MMC Card
In order to enable MMC card, switches 5, 6, 7 and 8 on the SW1 must be turned on, as
shown at figure 38. By doing that, SPI communication lines (SCK, MISO and MOSI) are
connected to the microcontroller and CS line is turned on.
