Cricket avr ATMEGA644 h-bridge with arduino support
Arduino support is now available for the Cricket. Program the Cricket using the Arduino programming environment. A sketch is available for the Cricket.
The Cricket is programmed in C using either a GNU C Compiler, AVR Studio V4.13 or higher with GNU C integrated with the IDE or a third party IDE such as ICCAVR from ImageCraft. The ATmega644 may not be programmable with ICCAVR so a special utility (ISProg.exe) is available to program the processor. Check the SOC Robotics web site for program examples and ICCAVR project files. ICCAVR project files are on the included CD. Example code is provided to read the accelerometer, communicate on the I2C port, run the H-Bridges and how to use the UART. The example Project files that come with the Cricket were written using the ImageCraft ICCAVR Windows IDE. With the release of AVR Studio V4.13 the open source AVR GNU C Tool chain is now integrated with the AVR Studio V4 Windows IDE and is recommended for cost sensitive development projects. The ImageCraft IDE is a low cost commercial C development environment and includes support for 64bit floating point operation in the PRO version.
The Arduino Programming Environment can be used to program the Cricket. Sample files are provided to help configure the Arduino environment for the Cricket. The optional USB10 can be used to program the Cricket using the Arduino bootloader.
