Oh... yes probably this is the reason.
However, last night I made some steps forward.
At first I try to remove the DAC HAT and wire all the stuff directly to the Raspy.
Results:
1) The wake-up/shut-down button works perfectly. With a short touch it wake-up or shut-down the system. With a long touch (at least 4-5 secs) it forces an hard-reset.
2) The display works! Not completely, but works. I don't remember the right sequence, but at the beginning, running from the console the WinstartOLED_Display.py driver, it performs correctly the tests . The same using a simpler TestOLED.py script that simply write some messages on the display. Then I try to run RaspDacDisplay.py (the original one ) and ..wow... Artist, Song, Elapsed/Duration time all it works fine (with scrolling text when required)..
After some minutes.. the system had some problems...
..and this is maybe due to the non perfect soldering. Is it correct?
So , now the question is: how can I control the soldering (in addition to a visual accurate inspection)? Using a kind of tester? Running a test program?
thanks in advance for any suggestions!
