Re: configuring the i2c pins on esp32-c6-devkit-m1 PostbyESP_Sprite»Fri Apr 05, 2024 1:25 am No. You can use any GPIO that is not otherwise used (e.g. by the internal flash chip, or by something your code already uses). ...
I apologized if this is a dumb question, I am new to ESP32 and not from EE background. I would like to know where are the I2C pins on the ESP32-PICO-KIT. I cannot find much information on this board and I can't see any labels for the SDA and SCL pins in the documentation on...
I was hoping to use I2C but also use another toggle switch to put the ESP32 into sleep mode by grounding either pin 21 or 22 and doing a digital read on these pins. Is this possbile? also I'd like to wake up the ESP32 once the toggle has released ground. I'd use another pin ...
I have also tried an ESP32 board, and they work fine, however I cannot seem to make them work on the ESP32-C3 Super Mini. I have connected the sensor (PCT2075D) to pins 8 and 9 (SDA and SCL). I then ran a sketch pct2075_test.ino (https://raw.githubusercontent.com/adafr ....
这是如何更改 esp32 i2c 引脚的示例。我将它用于我的 ESP32 和 bmp280,但同样用于 Arduino 和其他传感器。 #include <Wire.h> #include <Adafruit_Sensor.h> #include <Adafruit_BMP280.h> Adafruit_BME280 bmp; void setup() { Wire.pins(12,2); //new SDA SCL pins (D6 and D4 for esp8266) ...

The ESP32 will communicate with the PCF8574, which uses I2C communication, and this in turn will control the LCD. The PCF8574 I2C expander is shown below. As you can see abovePCF8574has 4 input pinsGND, VCC, SDA, SCLand 16 output pins. We will connect our LCD1602 to these 16 output...
