My pHAT BEAT pivumeter doesn’t work right.
Visually board looks OK, but:
On every boot (after the initial curl https://get.pimoroni.com/phatbeat | bash full install)
random combination of LEDs light up - and stay on, no matter what I try.
Sometimes first tree, sometimes one, seldom none.
Always (what seams to me) at full brightness.
No combination of gpio setting to pins 12, 16 or 18 (or any other I’ve tried) seem to change anything.
They get rather hot after some time obviously.
None of python examples give any effect.
Nothing after python calling phatbeat.set_pixel(params), phatbeat.clear(), phatbeat.show() .
The audio part works as expected, same with buttons (apart from hue-control.py not changing colors obviously).
I’ve checked whether there are short-circuits between header pins, or if there are some lack of connectivity in header connector - all comes out fine (I did reflow on header just to make sure).
I’ve even made simple oscilloscope from my cellphone - using https://f-droid.org/packages/org.billthefarmer.scope/ and mic connections from phone minijack - and there seems to be an digital signal on 16 and 18 pins ( without resistors even - i know- risky ).
Reboot (not cutting power to hat) does not change the random LED configuration, only shutdown and new start.
Is this some weird timing issue? Or just faulty hat?
