ELECTROSTATIC WARNING

The PIC32-MX460 board is shipped in protective anti-static packaging. The board must not be subject to high electrostatic potentials. General practice for working with static sensitive devices should be applied when working with this board.

BOARD USE REQUIREMENTS

Cables: Depends on the used programming/debugging tool. It could be 1.8 meter USB A-B cable to connect PIC-ICD2 or PIC-ICD2-POCKET to USB host on PC or RS232 cable in case of PIC-ICD2-TINY or other programming/debugging tools. You will need a serial cable if not for programming, than for configuring the board. You will also need a USB OTG cable.

Hardware: Programmer/Debugger – most of Olimex programmers are applicable, for example PIC-ICD2, PIC-ICD2-POCKET, PIC-ICD2-TINY or other compatible programming/debugging tool.

!!!Warning!!! When you want to program this microcontroller with PIC-ICD2, PIC-ICD2-POCKET or PIC-ICD2-TINY, before connecting the programmer to your target board, you should first connect the programmer to your computer and open MPLAB. There, first from menu Configure – Select Device – choose the microcontroller you are about to program, then from menu Programmer – Select Programmer – choose MPLAB ICD 2, wait while MPLAB is downloading operation system, and after ICD2 is connected – check in menu Programmer – Settings – Power – there is option – Power target circuit from MPLAB ICD 2 – this option should be forbidden, you could not select it. Now it is safe to connect the programmer to your target board.

I 2 C

The PIC32MX460F512L microcontroller has two I2C interface modules, denoted as I2C1 and I2C2. Each I2C module has a 2-pin interface: the SCLx pin is clock and the SDAx pin is data.

Each I2C module ‘I2Cx’ (x = 1 or 2) offers the following key features:

– I2C Interface Supporting both Master and Slave Operation.

– I2C Slave Mode Supports 7 and 10-bit Address.

– I2C Master Mode Supports 7 and 10-bit Address.

– I2C Port allows Bidirectional Transfers between Master and Slaves.

– Serial Clock Synchronization for I2C Port can be used as a Handshake Mechanism to Suspend and Resume Serial Transfer (SCLREL control).

– I2C Supports Multi-master Operation; Detects Bus Collision and Arbitrates Accordingly.

– Provides Support for Address Bit Masking.
