i2c.master: I2C transaction unexpected nack detected with esp-idf 5.3 #27

Closed blfuentes closed 2 months ago

blfuentes commented 2 months ago

I'm trying to follow the sample just to show some text in a ssd1306 128x32 but I'm getting this error after flashing: Board: ESP32-S3 framework: espressif 5.3

The code is just the textdemo:
