LipSync stuck on Splash screen #8

Code successfully compiles, but gets stuck on splash screen. Buttons are non-responsive. Using Adafruit Tiny USB library version 2.3.3 yields the same effect.

Troubleshooting using the LipSync_TestBasicFunction code showed that the LPS33HW sensor was not detected, but the LPS22 was. Data streaming showed a 1 for the state of the magnetic sensor, and zeros for x, y, and z magnetic readings. The tube pressure sensor was also reading 0 pressure and 0 temperature. The ambient pressure sensor read normal ambient pressure (1000 hPa) and temperature (20 C). Reseating the STEMMA QT cable within the joystick gimbal resolved the problem.

It's unclear where the normal firmware was getting stuck during initialization.

  1. Some error-checking should be added and displayed on screen to make it easier to diagnose
  2. Some sort of testing firmware could be added during assembly steps to check connections before the entire joystick is assembled
