ESP32基于自带控制器实现CAN总线通信。ESP32包含一个TWAI控制器，支持标准格式和扩展格式两种帧类型。ESP32 TWAI控制器具备接收过滤器功能，允许控制器根据报文ID过滤接收报文。接收过滤器的配置包括Code值和Mask值，Code值指定位排列模式，Mask值可屏蔽某些位。ESP32 TWAI控制器具有错误状态和计数器功能，...

TWAI 有4条物理信号线,TX RX BUS-OFF 和 CLKOUT ,其中BUS-OFF和CLKOUT是可选的。 TX和RX :这两根线是can的标准总线,需要外接一个can总线收发器芯片,显性电平是0V,隐性电平3.3V BUS-OFF:这根信号线主要是用于判断错误标志buf-off ,当bus-off 标志触发的时候这个引脚输出低电平。 CLKOUT:输出APB 始终的预...
