ST1000 embedded TinyPilot - Projectlog & Questions

[seandepagnier]

Update:

Got the IMU working by disconnecting the Nokia screen. Somehow something went wrong with the screen which gave noise or ruined the 3.3V supply from Pi. Screen was also having troubles working and didn't show any backlight, so probably something went wrong there, or the screen itself is just bad. But hey, a functioning IMU is more important!  
update: could have been due to a shortage I had on the breadboard which consumed lots of power. Will test with the screen again soon.
update 2: screen and IMU have been stable for ours yet. Backlight is also functioning since I discovered it needed to be connected to ground instead of 3v3

Still wondering about the advanced / factory IMU calibrations though. Installed the PyPilot plugin to my notebook, but didn't have all the fancy options from OpenPlotter in there. Let's see how it performs on the boat after some calibration time though. Seems quite slow in it's reactions for now and pitch and heel will drift over time.
update: the IMU seems stable now. Somehow I was in the misunderstanding that you have to start the six-sides-of-a-box calibration by pressing some button or running some command. But now I finally understood that it is automatically detected when you perform this procedure.

Great to see you built your own tinypilot!  I am glad to see the picture.

You can change many parameters to make reaction faster, try increasing the gains.
