Hi
I'm working on my Solartracer / Weather station project.
Goal is to have a Solarpanel which faces towards the sun and follows.
I use a Teensy4.1 for this project. There are several sensors attached and finally the data will be transferred by an Adafruit LoRa module from time to time.
It is this Adafruit Module. I have already ordered a PCB which I have designed by myself. But now I have an issue that the LoRa module doesn't work.
Here are is the error which is thrown:
I made a test.
Removed the the level shifter and changed the DIO0 LoRa module connection from pin 8 to pin 35. Now the LoRa module works fine.
But I don't understand why exactly that it don't work as long as DIO0 is on pin8.
Plot of the schematic is here or attached to this post.
And the project can be found on my Gitlab site.
When I look at the pinout map from the Teensy4.1, I see that pin 8 is also labeled as sda0 (lowercase). Normally I use the pin 18 for SDA0 (uppercase).
Does anyone know why pin8 is labeled with sda0? I did not found useful information about this. Is this pin like shared or something similar?
Therefore I write this post to find a explanation about, why the other pin works and what it is about the sda0 pin8.
Best regards
Simon
