play wav file from SD card

shmow

Hey All,
I purchased the SD adapter board and have been trying to play a WAV. file.
I've found a sample code (excellent and thorough - http://www.instructables.com/id/Make-a-Talking-Clock/?download=pdf); but it's somewhat complicated for my little brain to decipher.
If you look at the main portion of the enclosed program then you'll see a simple sub-routine call with it's related commands to play files.
However, a big fat nothing happens.
I've tried all sorts of things - I've even flipped the SD card thinking I've got it in the slot upside down.
No luck.
Is there any help out there?
Regards,
Shmow

You might be chasing two project at once.. Always tricky..

Cross check your SD setup with something like FemtoBASIC or PropDOS which are known to work across a variety of configurations.
(Don't be afraid to switch out your SD card itself in this test.)

Once you verify that your hardware is working correctly, then turn your attention back to your WAVplayer code.

You might also find the Propeller Cookbook, page 5 useful.

Hey OBC,
this PropDOS, what application do I open it with? I've discovered it's not Propeller Tool.
Shmow

shmow

Uh oh! I need the combo keyboard and video - eegads!

Oldbitcollector (Jeff)

You'll need to rename the file with a .zip extension as the forum didn't like the upload.

Then you should be able to extract and use it with the Propeller tool.

Hi Shmow,

one thing that will help forum members help you is for you to place your code between two "code tags". They look like this except you need to take out the spaces

[noparse][[/noparse] code ]

[noparse][[/noparse] / code ]

  That way the indentation
     of your code
       will be preserved

Oldbitcollector (Jeff)

No video or keyboard huh? Try this instead..

You'll have to uncomment the sections you want to activate in the code.. Don't worry it's well documented.

OBC,
thanks I'm all over it like stink on a skunk.

OBC,
what is PST? Can I use hyper terminal instead?
Shmow

shmow

Yes, I'm using hyper terminal.
Thanks a'plenty.

It's the Parallax terminal program, it's a lot better than HyperTerminal. You can download it from the Parallax web site (Propeller Downloads).

I have the PST connected.
After running a test, it states that: "SD card expected..."
I know this card works because I've used a separate card reader on it successfully.
I've checked the connections of the pins and they are correct and true.
Could I have damaged the SD card adapter while soldering it together - specifically the card reader?

Rayman

Are you trying to drive a speaker directly from a Prop pin?
You are using amplified speakers, right?

Hey Rayman,
ultimately, the file will be fed to a "line out" of an amplifier.
Currently, I have an emic, and I want to replace it with the SD/WAV design.
That's great for the offer! I do want to keep the SD option.
It looks like I'd use your sysdep_demo_ser.spin.

Anything is possible.. Which card reader are you using?

The "SD card expected..." message means that the card failed to mount. double check pins settings in the CON section.

Just for giggles.. Have you tried a different card?

Yes on both counts - checked the con settings and used another card.
This hill is getting steeper, but I bet the view will be worth it.

Oldbitcollector (Jeff)

Yes, conquering SD is truly worthwhile..

You didn't answer which SD interface you were using..

Any chance that you have a spare molex (or equiv) SD connector you could wire up?
I've manged to run many SD setups without the pull-up resistors with simply the four required wires
directly from the Propeller to the SD card. Follow the example given in page 5 of the Cookbook link I gave you earlier.

The only problem I've ever run into was a Sparkfun SD/pcb that I ordered earily on, once I shifted to other options
SD has been smooth sailing.

the reader is the one which came with the parallax SD Card Adapter (product #32313)
it's the 3M product.

Oldbitcollector (Jeff)

Time to whip out a meter and check the connections.

I'd check from the rear of the card to the pin. Don't worry about CD and WP at this point.

I've done that - I'm beginning to think I cooked the reader.
I used a hot air solder to make the connections and there was some damage on the sides where the two large "feet" are to solder.
I figured it was just cosmetic; perhaps I'm mistaken.

Oldbitcollector (Jeff)

Ouch!

Time to whip out four paperclips and a piece of perf-board..

Someone unfolded the paper clips to one bend, inserted them through some perfboard and soldered to the back side.
Slid the SD card between the perfboard and the paperclips.. If I can find the photo you'll get a chuckle.

It really isn't much more than four I/O connections and Vss/Vdd

on the reader, I checked the isolation of between the GND pin and the CD pin.
There's a short there (or they're connected for a reason).
Those two pins are the small pair right on the end.
Should I isolate them?

shmow

It's the little, tin guard or fender between the GND and CD; I've soldered the fender to CD.

shmow

I have the reader working!!!
The problem was the card?!!
I pulled another card from my camera and used it.
Prior to that I was using a pair of cards that have been
sitting in my desk for years.
Now the next step is to get my sample code to work.
'Cause I'm getting no sound or anything.

Oldbitcollector (Jeff)

Most Excellent!

Fall back to Rayman's WAV player code from OBEX. (I think he gave you a link somewhere in this thread.)

That'll help you sort out the other side of the issue.. [noparse]:)[/noparse]

Hey All,
now that I have some kind of communication between the prop and the SD reader,
I'm trying to get the prop to send the WAV. file (MORN.WAV) to the little speaker.
I've looked at several examples and I've had no luck.
My oscilloscope shows there is a signal going out to the speaker from pin 7, but nothing is heard.
Does anyone have any suggestions?
Regards,
Shmow
