I assembled my Radio Music yesterday but can't get it working properly.
I explain:
all output is scrambled
I uploaded 2017.2 firmware (Teensy is ok, see later) -> scrambled output
I uploaded the test firmware -> works ok
I upload alternative firmware -> that seems to work as far as I tested (it was no garbage)
I uploaded RadioMusicA2.hex and that works fine! Only the reset button hangs the module
I uploaded the suggested .RAW files, I didn't even bother to play my own WAVs
Used SD card Sandisk Ultra Micro SD XC1 64GB, repartitioned to 32GB and formatted to 32GB as well as 16GB
(but remember, it works with the RadioMusicA2.hex firmware)
module randomly hangs when I press the reset button. I don't seem to be able to choose banks as described in the manual...
UPDATE: I removed the Teensy from the module and ran the test program ino via Arduino IDE
The Time CV shows an abnormal high value ? (max is 1024)... The value changes when I put CV on the START JACK
So maybe the Teensy is faulty after all?
Channel pot=232 Time pot=205 Channel CV=207 Time CV=26843779
Channel pot=227 Time pot=232 Channel CV=209 Time CV=26843799
Channel pot=233 Time pot=227 Channel CV=201 Time CV=26843789
Channel pot=222 Time pot=216 Channel CV=194 Time CV=26843783
Channel pot=231 Time pot=218 Channel CV=228 Time CV=26843778
UPDATE 2: grounding the pin 8 (TimeCV) does not set the value to 0 or 1. So I assume my Teensy is broken :(
UPDATE 3: changed Time CV pin to A5 (#define TIME_CV_PIN A5 in interface.h) and now it works (except the time CV of course)
UPDATE 4: changed test code in order to have normal values - everything works
Conclusion: there is a bug in the hex files.... every other fw works, except 2017.1 and 2017.2
Maybe a new Teensy version ????
