Re: ESP32-S2-DevKitM-1(U) USB , Default I2C Pins Postbyrudi ;-)»Sat Oct 09, 2021 3:48 pm thanks for detailed explanation about document structure @ Espressif..this helps for sure. Actually I could find that
driver “Wire.h“, it’s by default set to I2C0 peripheral, and the (SDA & SCL) lines are set to defaults as shown in the previous section. However, you can still change the ESP32 I2C default pins in the setup function and route those signals to any GPIO pins you want. As shown...
Hi All, Does anyone know if its possible to use I2C pins for both I2C as well as digial input pins at times when its not being used for I2C communication? and to add another spanner into the works can it be a rising interrupt when in sleep mode?
which was my original problem. I have a AT30TS75 temperature sensor which only has I2C. I could not get I2C working on pin 21 and 22 using Arduino IDE, which I believe are the default pins. I was wondering if there is a way to change the pins from 21 and 22 to 32 and 33. How...

By default, the ESP8266 will print log messages and open a CLI console on UART0, which can be accessed via the same USB UART used for bootloader flashing: ESPPORT=/dev/ttyUSB? docker compose run --rm monitor If using the UART0 pins for other IO (e.g.spi-ledsI2S interface), the ...
这里是三个通用的传输接口,串口,I2C,SPI 数字接口 Timer接口 DAC的接口 多次出现uint8_t类型 这个地方是定义所在 unsigned char没有符号位,因此能表示0~255,这个好理解,8个bit,最多256种情况,因此无论如何都能表示256个数字。 在实际使用过程种有什么区别呢?
ESP32 I2C Pins Note: If we use other GPIO pins of ESP32 for I2C communication, we can define other pins inside our Arduino sketch. We don’t have to use default I2C pins. You can learn more about I2C communication here: I2C Communication Introduction ...
i2c_param_configwill configure the parameters we just set.I2C_NUM_0is the I2C instance we are using. If your board have more than 1 I2C, then you should define the instance as per the pins you are using. After configuring the parameters,i2c_driver_installwill install the driver. The para...
