microSD frustrations

Erlend

Last time I built something I had no problems playing wav from the SD card. Now I've wired up a new build (uing the Prof Dev board). This time I messed up the pinouts to the card adaptor and the wavplayer is not working. First I thought something had burned, but in my struggle to diagnose & troubleshoot, I found SDCard_micro_01 from the obex, and succeeded in opening a file on the SD. On the PC it is corrupted, though, so I cannot check if the text was actually written. The SDCard_micro_01 program was out of sync with fsrw so I had to do some edits to make it run. I am not sure I trust it to be the best test program. Are there any better programs for this purpose?

I am frustrated by the wilderness of wav & SD objects on obex. I simply want to play wav from SD, and to readwrite numbers that I want to assign to variables. On top of this, if the object(s) allowed for SD-pinouts and audio-pinouts to to be part of the object method call parameters instead of being hardcoded in the object itself, I would be very happy. Not really a problem, just against my coding style.

If I remeber correclty with fsrw you set the pins at mout.

Agreed, the fsrw is good, but I would like to do a call something like this: PlayWav(file,pinAudioR, pinAudioL, pinSDdo, pinSDclk, pinSDdi, pinSDcs), and as far as I can see the wav player objects all hardcode these pin numbers.

Could you post the code?
Maybe it is possible to tweak the wav player object.

Have you tried Kye's KISS WAV Player Driver?

KeithE,

Fantastic - this looks to fulfill all my wishes. I look forward to try it tonight.
I'll test with a new SDcard in case the old one have been damaged somehow. After that I do not know how to eliminate any more possible faults.
