| Abstract: | TMS320F2812 is a 32-bit fixed-point digital signal processor(DSP) chip used in control purpose. The reinforcement of its enhanced controller eCAN is analyzed.The hardware node design of CAN built by eCAN in CAN bus communication was mainly introduced.The baud rate bit-timing calculation method,the flowchart in CAN software design and its corresponding C language debug program about initialization,send and receive were given.The debugging technique in practical application was also summarized.The design based on electric vehicle has been successfully used in hybrid power vehicle energy integrated control system. |
