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 ...
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: 1818 Joined: Mon Oct 17, 2022 7:38 pm ...
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个字节 i2c.writeto(0x3a, '12') # 想地址为...

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 ....
Re: ESP32-C3 i2c sensors weird behavior by ESP_Sprite » Mon Jun 24, 2024 1:49 am Probably a library issue. As you have found, the C3 doesn't have dedicated I2C pins; you can use any of them for I2C. However, libraries might make assumptions there.2...

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 ...

I recently upgraded my setup from esp-idf 5.1.2 to 5.2, and am trying to write a driver for a magnetic encoder that configures the chip via i2c. This code/driver runs fine on an esp32-c3 seeed module I have, but crashes the same way on two different esp32-s3 boards I've tried....
