然而,您可以决定哪些引脚是UART, I2C, SPI, PWM等-您只需要在代码中分配它们。这是由于ESP32芯片的多路复用特性。 虽然您可以在软件上定义引脚属性,但默认分配的引脚如下图所示(以ESP32 DEVKIT V1 DOIT板36引脚为例-引脚位置可以根据制造商而改变)。 ESP32 片上存储信息: • 448 KB 的 ROM,用于程序启动和...
I need help figuring out the default I2C pins for the ESP32-S3 DevKitC 1 model. I have esp32_hal_i2c.h and LiquidCrystal_I2C.h included in my code and other than that nothing that should change the device pinouts. I am trying to find the SDA and SCL pinouts. Please and thank you...
Although you can define the pins properties on the software, there are pins assigned by default as shown in the following figure (this is an example for theESP32 DEVKIT V1 DOIT boardwith 36 pins – the pin location can change depending on the manufacturer). Additionally, there are pins wit...
The ESP32 operates on 3.3V and can be programmed with ESP-IDF or with Arduino IDE which is still under development; the Arduino operates at 5V and is known for its easy-to-use Arduino IDE and strong community support. So to conclude, if you have prior experience with programming and your...
3.1: ESP32 ADC Pinout As mentioned earlier the ESP32 board has 18 ADC channels. Out of 18, only 15 are available in the DEVKIT V1 DOIT board having a total of 30 GPIOs. Take a look at your board and identify the ADC pins as we highlighted them in the image below: ...
But cannot have it running in my esp32 devkit v1 (following your instructions). When running your “Getting the LCD Address” code in arduino uno, the program says that the lcd is in address 0x3C, but I have it running in address 0x27. In the esp32… The LCD receives the proper 5V...

There are different types of ESP32 development kits available but the function of GPIO pins remains the same across all development boards. You can define the pins the same way in firmware also. The following picture shows the pinout diagram of the ESP32 DEVKIT V1 DOIT board. In your versio...
