Instead of using power supply via USB MINIB connector, it is also possible to
use AC/DC power supply via screw terminal CN1. Connected power supply
source voltage can vary from 9 to 32V DC and from 7 to 23V AC.

2. Programming with bootloader
For programming, microcontroller use bootloader program which
is preinstaled in to MCU memory. To transfer .hex le from a PC to
MCU you need bootloader software (mikroBootloader USB HID)
which can be downloaded from:
After software is downloaded unzip it to desired location and
start mikroBootloader USB HID software.

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.
The microcontroller can be programmed with mikroProg
programmer. The mikroProg programmer is connected to the
development system via the CN10 connector, Figure 3-1.

ICD3 programmer
The microcontroller can be also programmed with
ICD3 programmer. This programmer is connected to
PIC32MX7 board via on-board ICD connector CN5.
4. Programing with
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.

If you accidently erase bootloader program from MCU memory it is possible to load it again with external programer. MMB MX7
USB HID Bootloader v1.10.hex le is located in Firmware sub folder, Page 10.

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 die rent colors.

6. Temperature sensor
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).
