4. **硬件问题**:ESP32-C3的硬件可能存在一些问题,导致CAN总线通信异常。可以检查硬件连接是否正确,...
2.给485所在的串口号发送信息,将会收到同样的信息 测试CAN总线 程序一启动会检测CAN状态.可以在日志上面看到CAN测试结果 提示 后面是介绍整个程序,如果是初学者大概看一下就可以. 写后面的目的是给已经有基础的了解一下整个程序执行步骤. 便于迅速的实际应用到项目中. 对于初学者按部就班的一节一节的学习就可以....

we are planning to combine XIAO ESP32C3 andCAN BUS, aiming at a cost-effective and compact prototyping kit or device. It could be asa tiny CAN analyzer,a CAN-to-MQTT data loggeror we could addadditional onboard sensors, etc. Do you think it is a good idea to meet...
You can now compile ESP-IDF projects. Go to the project directory and run: idf.py build 正如输出所示,我们现在已经准备好开始构建了! 启动流程 ESP32-C3 API指南中详细描述了引导过程。主要的要点是,引导是一个两阶段的过程,第一阶段引导加载程序存储在ROM中,无法修改,它负责加载第二阶段引导加载程序。

Can an esp32 have at the SAME time a wifi connection (AP or client) and some other local connection (like esp-now, BT or some other ESP to ESP wifi connection)? My project is a 2 part thing. Part 1 has an esp32 driving 2 stepper motors. Part 2 has an esp32 driving a screen ...
我在arduino平台上开发esp32c3。采用了freertos创建了几个任务。主要有主循环loop和CAN数据读写任务。主循环的优先级高于CAN读写任务。现在的问题是我在CAN任务执行完毕检查twai_get_status_info。发现在TX队列里有一个数据。但是当任务到主循环的开头再次读取状态时则发现数据跑到了RX队列,而实际上CAN总线上并没有...

After turning off the WiFi, the battery voltage can be measured with ADC2. The second issue is the conflict with the WiFi and how that impacts using ADC2. Going back to the single_read example: code exert: while (1) { adc_raw[0][0] = adc1_get_raw(ADC1_EXAMPLE_CHAN0); ESP_...
