stm32f103的CAN的时钟主频是36M,分9频就是4M,在除以(5 + 2 + 1)得到500K的波特率。 注意:stm32cubemx生成的CAN代码是不带过滤器的,需要自己手动添加。 CAN之数据帧格式 代码部分 CAN初始化 CAN_HandleTypeDef hcan1; CAN_FilterTypeDef sFilterConfig;//CAN初始化:/* CAN init function */ void MX_CAN_I...
Re: 计划做一款基于ESP32 S3的调试工具,具备工业485、CAN调试功能 memory 说: CAN芯片是 PHY吗? 见:ESP-IDF的twai_alert_and_recovery例子: | Supported Targets | ESP32 | ESP32-C3 | ESP32-C6 | ESP32-H2 | ESP32-S2 | ESP32-S3 || --- | --- | --- | --- | --- | --- | --...
RS232/RS422/RS485通信接口区别RS-232、RS-422与RS-485标准只对接口的电气特性做出规定,而不涉及接插件、电缆或协议,在此基础上用户可以建立自己的高层通信协议。例如:视频服务器都带有多个RS422串行通讯接口,每个接口均可通过RS422通讯线由外部计算机控制实现记录与播放。
