Hey guys,
I need help with my FYP. Im trying to make an accelerometer based mouse using a single 3 axis accelerometer(MMA7260). Ive chosen ATmega16 as my microcontroller. I've got two options of either using CVAVR or AVR Studio 4 as my compilers and have Ponyprog2000 as my programmer. My development board is from Thinnkware.
Here are some of the problems im facing :
1) The code for the project is written for CVAVR but even if i execute a simple loop(for,while,etc) to flash LEDs in CVAVR,it does not run on the development board. I do not know how to program using AVR studio 4 (dont know the functions or header files)
2) I need to send the signals to the PC via PS/2 protocol. Ive obtained a PS/2 wire from an old mouse but am not sure how to interface it with a microcontroller. Do i directly connect it to any port of the uC and program that port to send bytes of data? or do i send the data from the uC first to a voltage converter like MAX232 and then send the Txd values to the PS/2 pins? because when i opened up my optical mouse, i saw a small 16 pin uC soldered onboard.
3)My 3 axis accelerometer has mode selection for various values of sensitivity(1.5G,2G,4G,6G). I want to know which value should i go for when i test my project - high sensitivity(1.5G) or low sensitivity(6G). Also what is the difference between dynamic acceleration and static acceleration? do i need to set sensitivity values for both these modes??
Any help in the above matter will be highly appreciated. Please help. Thnx
