I have a esp32 C3 mini dev board, and it worked well before. Recently I used it to read distance from VL53L1x laser module through I2c port, however it always report errors and cannot detect i2c devices. I was using arduino framework and wire library , gpio 8 for sda and gpio 9 ...

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. ...
The pins indicated are for the IOMUX, but for 99% of the use cases you can actually use any (not otherwise used) GPIO for this using the GPIO matrix. Because I2C is generally quite slow, it doesn't have an IOMUX connection, and does not have 'standard' pins for it. Still, the ...
硬件,即直接利用 芯片中的硬件 I2C 外设,只要配置好对应的寄存器,外设就会产生标准串口协议的时序。 二、ESP32实现I2C通讯 本文以OLED显示为例,介绍ESP32中,通讯协议的使用方法。 1. ESP32-I2C介绍 上文中,介绍了两种不同的实现I2C通讯的方式,一种是通过软件模拟的方式,控制GPIO电平实现,另外一种是硬件实现方式...

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 ...
