软I2C(使用 bit-banging)可以工作在所有可输出引脚,通过machine.SoftI2C类进行访问: from machine import Pin, SoftI2C i2c = SoftI2C(scl=Pin(5), sda=Pin(4), freq=100000) i2c.scan() # 扫描设备 i2c.readfrom(0x3a, 4) # 从地址为0x3a的设备读取4个

ESP32 Set I2C Pins (SDA, SCL) When you include the Arduino Core I2C 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...
Hello! I wondered if there are specific pins to use for I2C and SPI for the ESP32-C3-MINI? I haven't been able to find this in a datasheet/ anywhere else. Is there room for both I2C and SPI ? Thanks in advance!MicroController Posts: 2181 Joined: Mon Oct 17, 2022 7:38 pm ...
Summary For the ESP32C3 (XIAO C3 for example) the default I2C pins conflicted with the USB pins resulting in REPL hanging after using the new I2C initializer without parameters. Reference: #17103 ...
I am working with the ESP32-C3-MINI SoC for a PCB board. I need to have SPI and I2C communication to two devices (SPI to device one, I2C to device two). I cannot devise a pinout for these, as most of the breakout pins appear to be used for the internal SPI flash memory. ...

本次实验采用的是ESP32-C3,可以使用Arduino来完成测试工作,这里我采用的是Arduino默认的ESP32-C3的默认I2C接口,你也可以在程序里指定使用哪些IO作为I2C。 默认接口配置文件在以下目录可以找到 C:\Users\Mint\AppData\Local\Arduino15\packages\esp32\hardware\esp32\2.0.9\variants\esp32c3\pins_arduino.h ...
