因此,如果您使用Wi-Fi,并且无法从ADC2 GPIO获取值,则可以考虑改用ADC1 GPIO,这应该可以解决您的问题。 ADC输入通道具有12位分辨率。这意味着您可以获得0到4095之间的模拟读数,其中0对应于0V,4095对应于3.3V。您还可以在代码上设置通道的分辨率以及ADC范围。 ESP32 ADC引脚没有线性行为。您可能无法区分0和

When sending data to the GPIO pin 5 for example, no data is seen on a scope at this pin, I tried and checked other pins, same behaviour. Some sit at 3.3v all the time, some sit at zero volts all the time. Questions are, does the Devkit V1 have a CAN controller built in, does...

copercini @PITDEVBR by default the pins of serial1 arerx1Pin = 9; tx1Pin = 10;and serial2rx2Pin = 16; tx2Pin = 17; But you can set it on any pin if you want:Serial1.begin(9600, SERIAL_8N1, gpioX_rx, gpioY_tx);
下图显⽰了ESP-WROOM-32引脚。如果使⽤ESP32裸芯⽚构建⾃定义板，可以将其⽤作参考：注意：并⾮所有的GPIO都可以在所有的开发板中访问，但是每个特定的GPIO都以相同的⽅式⼯作，⽽不管您使⽤的是什么开发板。ESP32外围设备 ESP32外围设备包括：18个模数转换器（ADC）通道 3个SPI接⼝ 3个UART...
这里使用的开发板是:ESP32-C3-DevKitM-1 选择串口 使用USB 线将 ESP32 开发板连接到电脑后,然后在 PC 桌面右键单击【此电脑】图标,选择【管理】菜单项,在【计算机管理】中可以查看连接端口,如下图所示: 看到开发板连接的串口,每个人的串口可能不同,我这里是COM7, 请记住串口名,您会在后续步骤中使用。
