ESP32 有 10 个电容式触摸感应 GPIO。当电容负载(例如人体皮肤)靠近 GPIO 时,ESP32 会检测到电容变化。 虽然ESP32 共有 10 个电容式触摸感应 GPIO 引脚,但其中只有 9 个引出到 30 引脚 ESP32 开发板两侧的排针。 读取触摸传感器 读取触摸传感器非常简单。在 Arduino IDE 中,您可以使用该touchRead()函数,该...

Maybe you are using the function wrongly - on esp32,analogInputToDigitalPin(p)is meant to convert "ADC channels" to GPIO pin numbers. ESP32-S3 has 2 ADC units with 10 channels, i.e. ADC1: channel 0...9 ADC2: channel 10..19 ...

确保它是GPIO2而不是A0或D0。开始 要让XIAO ESP32C3真正被Micropython编程,需要两个步骤(“PC上的Micropython配置”和“XIAO ESP32C3上的Micropython设置”)。设置完成后,您可以从每个演示程序中一步一步地复制代码以实现完成。 在PC上配置Micropython...
