I recently bought 2 trill sensors but unfortunately cannot get them running.
Initially I wanted to use a ESP32 MiniKit V1.1. I used Io22 and Io21 for SCA and SCL. From what I have seen there are no pull-up resistors build in, so I tried both with and without 5k Pullups on SCA and SCL.
Sadly, I always only get the following message when using trill bar-print example on Arduino IDE and Platformio on VSCode
“failed to initialise trillSensor
Error code: 2”
I didn’t trust myself and the ESP32 so much, so I bought a Arduino Uno R3, to be able to follow the instructions on https://learn.bela.io/products/trill/trill-and-arduino/. Using A4 and A5 for SCA and SCL and also trying both with and without 5k pullup resistors.
After doublechecking all the connections and reading out the signals I found the following.
There are only 2 short messages, 25ms apart.
EDIT: I have mixed labeling SCL and SCA, obviously , but they are connected the right way with with SDA on A4 and SCL on A5
I have also tried I2C scanners, and no device are getting found.
Does anyone have an idea what the problem could be and how to fix it?
Thanks a lot!
