ESP32-C3 i2c not work

Postby salviador » Tue Dec 07, 2021 5:56 pm

I use ESP-IDF 4.3, with "esp32-c3 devkit-02"
I am trying example "i2c_simple" but I have a continuous reset of the ESP32
SCL GPIO Num 6 (default)
SDA GPIO Num 5 (default)

Code: Select all

[code]

Are you sure the device is connected and addressed correctly? Those ESP_ERROR_CHECK checks can also trigger if a device doesn't properly ACKs packets, I think. Possibly using a logic analyzer to see what's going on on the line may help.

Which device is connected to the I2C bus? Does this device already have pullup resistors?
I suggest testing I2C addressing with this scanner
