Sound Module AppMod

demo

I've been working on a project with sound module, and it's been working fine, but now I can't
make it record or playback anymore (not with pushbutton mode or serial protocol).

I have tried to reset the chip with this code, without success:

PAUSE 500
SEROUT 4, 500 + $8000, [noparse][[/noparse]"!SM0I"]
PAUSE 100
SEROUT 4, 500 + $8000, [noparse][[/noparse]"!SM0M",149]

I have Board of Education with BS2SX.

Particularly since it worked before ...

1) Check your connections

2) Check your connections

3) ...

It would be unusual for the module to fail suddenly unless it had been wired backwards or connected to high voltage (> 5V).
There is no reason for something to stop working when it worked before (computers are like that) unless something has changed. Wiring loosens. Wires fall out of sockets. Wires break. People put wires back in the wrong socket.

Thanks for reply.

I been using 7,5V. Can that damage the AppMod?

Mike Green

If you're using the 7.5V to power the BoE, no ... because the BoE runs this through a 5V regulator and that's what the Sound Module uses.
