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 ...
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...
5. ADC On the ESP32 ADC functionality is available on Pins 32-39. Note that, when using the default configuration, input voltages on the ADC pin must be between 0.0v and 1.0v (anything above 1.0v will just read as 4095). Attenuation must be applied in order to increase this usable vo...
思路大概如下所示:ESP32-C3通过AIN0读取ET7207的模拟数据,通过IO控制RST/STR,麦克风模块输出连接ET7207的AIN接口。接下来介绍一下这个ET7207 这是一款采用 CMOS 技术制造的7 段图形均衡器。它将音频频谱划分为7 段:63Hz,160Hz,400Hz,1kHz,2.5kHz,6.25kHz,和16kHz。这7 种频率的信号经过峰值检测和多路开关选择...
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. ...
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: 2127 Joined: Mon Oct 17, 2022 7:38 pm ...

Refer to the ESP32-C3 datasheet. Component overviewPower Pins 5V - This is 5v out from the USB port. You can also use this as a voltage input but you must have some sort of diode (schottky, signal, power) between your external power source and this pin with anode to battery...

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 ...
