first post for me...
ive been trying to get the module working for some time today... and finally got it making sounds.
thx for all the information in this post, was very helpful!
except for the issue ive faced! Everything was hooked up correctly, formatted the sd-card (SanDisk 64mb) in fat16.. etc..
But nothing happened.. I only noticed that the busyPin-LED was glowing all the time... first i thought this might be normal, but it is not!
Even if it did react to buttons ive pressed or code changes iv made! But at that point of trying i didnt know that it aint normal, so i started looking for the problem:
- formated the SD-card x-times
- soldered the jumper to 5v tested, and then again back to 3.3v
- destroyed a in ear headphone to get the speaker
- took differend .ad4 files
- hooked everthing up again
- used different code snippets
- readed every post ive found
-....As a last desperated try i was just pressing slighty against the bottom side(between pin 8 and 9) of the sd-card, while it was mounted into the slot.
AND, some reaction, the busyPin-LED was turning off.. as i pressed some buttons i noticed sounds...!
Finally it worked for me.. So my conclusion is, that the SD-card might not have decent contact to the module, even if it looks fitted!
Hopefully this might help someone... like your posts helped me!
