[PIC] How OSI model's Physical & data link layer r useful in writing code for CAN bus

[Pallavi Burje]

hi,

I m doing project on CAN bus communication using PICDEM CAN-LIN 2 board. I want to monitor 3 sensors and if one of it will give wrong or repeated value then text message related to that lcd will display.. But i m not getting how are the steps to write C code for CAN bus transmission and receiver and OSI model's physical and data link layer are useful for CAN communication???.. so please help..

Refer following Link

actually Physical layer means connection we do physically with can that is we convert data to electrical waveforms.
Object layer and transfer layer comprises all service and function of data link layer.
and main protocol implemented in this layers that is handling of error and arbitration. Which data is to transmit to whom and which data receive from whom and for what.
