    You need to tell us a bit more about what you are trying to do and where you are stuck.

    Are you coding in C or assembler.

    Do you have a hardware set up to test.

    Is it  a commercial project.

    Do you have a specification for the code you need to write ot for the performance of the finished article.

    Sir,

          I doing my main project. I have to make the hardware setup for sensing motion of human body. The motion is sensed by using two strain gauges. The output of the strain gauge is connected to the  input of ad7796. ad7796 is a Low Power, 16-/24-Bit Sigma-Delta ADC for Bridge Sensors.The output from the ad7796 is connected to the atmega 16. The interfacing of ad7796 and atmega 16 is by using spi protocol. For that i have to write code for spi in embedded C.  Sir i need help.
