FW 3.4.0: SH1106 support + ticker changes

A project log for All-In-One Gamma-Ray Spectrometer

More sensitive to gamma radiation than a Geiger counter with the added bonus of telling exactly what's inside your samples!

Hey there,

you might have already seen the new firmware files on GitHub. With this new update, I added support for the SH1106-type OLED displays. This expands on the current support of SSD1306 screens.

Also, in this update I changed the way the ticker works in order to accomodate higher count rates. The way it used to work is by clicking on each and every detected pulse. This way, you could only go up to around 1000 cps until the buzzer just saturates. Also, due to the already high activity at background radiation (>20 cps or so), detecting changes was a bit harder.


That's why the ticker now only clicks at every 10th detected pulse. That way, you can get up to 10x the range for the buzzer without saturating. Also, stock background clicks are now way more relaxed.
