您好,在阿莫论坛看到您的帖子,这段时间也在测试这个小板子,想请教一个问题
调试步骤:
结合usb文件夹内案例和触摸感应例程,想用电脑接收触摸的编号
烧录后电脑可以识别为usb串行设备(COMxx)的方式
然后用一个usb转串口设备(profilic)连接p3.0和p3.1,gnd,使用两个串口助手互发信息模拟发送和接收
结果:
板子对应的cdc串口调试助手发送信息,profil…

I think that this module would be a great addition to other microcontrollers that not have USB stack. But for some microcontrollers like the ESP8266 or the ESP32 we need those lines.
So.... Here is t…

I've tried both with a CH552 and a CH551 module.
After power cycling the module, windows detects it, but under device status, the device status is "device cannot start (Code 10)"
