Just for a clarity of the experiment all modules were disconnected from Raptor and then following three tests were performed.
Case 1 – direct connect
[em]Setup: Raptor, UC_Battery_4xAA (socket #8), Tunes (socket #18), and Button (socket #10) [/em]
Tunes sample from website unchanged, as is, compiled and deployed - runs fine, plays melody(up, back down, arpeggio). On the cons side however, in the debug mode, code does not run fine, instead it sporadically play a note or two, or might not play at all…
Case 2 – through the hub – S2 – H4
[em]Setup: Raptor, UC_Battery_4xAA (socket #8), HubAP5 ( socket #2), Tunes (socket H4), and Button (socket #10)[/em]
In debug mode – inconsistently plays a note or two, it is definitely not a melody.
Standalone – inconsistently plays a note, or does not play anything. Reset produces different result, but mostly – no sound at all…
Case 3 – through the hub S2 – H8
[em]Setup: Raptor, UC_Battery_4xAA (socket #8), HubAP5 ( socket #2), Tunes (socket H8), and Button (socket #10)[/em]
In debug mode – plays one scream sound, it is definitely not a melody, or if it is melody then it is very compressed in time.
Standalone – on power on always plays something, but definitely not a melody. After resets usually there is no sound ( I was tired after clicking reset 15 times)
