Re: ESP32C3 - using pin GPIO18, 19 for USB? Postbymzincali»Wed Jun 08, 2022 9:26 am Thank you! For a brief moment the device showed up on my Mac with as a "USB JTAG/serial debug unit". I tried uploading a simple sample (SimpleTime), and after that I somehow must have sc...
合宙的 ESP32-C3 CORE 开发板有 经典版(含CH343转串口芯片)和简约版(USB直接拉通芯片),设备管理器中显示的串口号不同: 下载2个版本的线路图,D4-GPIO12,D5-GPIO13LED灯,KEY-GPIO19按键标上注记,可以看出经典版走 CH343-GPIO20/21,简约版走 USB-GPIO18/19 找到blink.py 稍作修改,就能亮灯。 保存+ 执...
