摘要
TMS320F2812是一种用于控制的32位定点DSP芯片,对其增强型控制器eCAN的增强特性进行了分析。重点介绍了CAN总线通信中利用eCAN构建CAN网络的硬件节点设计,并给出了CAN总线波特率位定时计算方法,CAN软件设计的流程和对应的C语言初始化,发送接收调试程序,总结了在实际项目应用中的调试技巧。这一设计基于电动汽车,已成功应用于混合动力汽车能量总成控制系统。
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.
