Cannot find i2c devices via stemma/qwicc port #225

Closed jaymedavis closed 4 months ago

jaymedavis commented 4 months ago

I have tried 3 different devices via the stemma port for i2c. Downloaded the example code from this repo, which scans sda 18 and scl 17.

What am I doing wrong? output is "No I2C devices found"

edit: I am using the esp32-s3 with the clear screen

The I2C JST Sh 1.0mm 4pin port is SDA43, SCL44

T-DisplayS3_Pinout

I presume that you have a LilyGO T-Display S3 non-touch screen and NOT the LilyGO T-Display S3 AMOLED? The I2C is the same but I like to clear that up. I have my own User Support GitHub repository here: https://github.com/teastainGit/LilyGO-T-display-S3-setup-and-examples This may be some help for you! The 'HotHead_temp_sensor' example is I2C. -Terry

Awesome, thank you @teastainGit! My I2C scanner is now finding my devices. Starred/saved that repo as well!
