Great. I'll still hold off uploading V0.3 of the library for the moment though.

Using the HCMP3.play() with directory and file and it works just fine. Oh ok, so it is actually communicating with the module then. That does rule out a lot of possibilities. I've taken one out of our current stock and tested it and it works fine. Here is the output from the example sketch: MODULE ...

Thanks for checking. The example sketch is a known working sketch so should defiantly work. If it's not even getting as far as reporting the card status then this would suggest there is something more fundamentally wrong somewhere. the module plays audio just fine, both through speaker and line out....

Thanks for confirming. I've added a new library function called DrawMode(). This will allow you to do what you need but its far more flexible and is more inline with how our graphics libraries work. It has one parameter which sets one of 3 drawing modes: DRAWMODE_NORMAL This is the default mode and ...

However, I seem to be unable to get the function "HCMP3.getPlayState()" to work or get a proper responce through the example. Can you confirm if you are getting a response from any of the other commands? I.e. is it completely unresponsive to any command or is it doing something? When you run the ab...

The only other problem antenna wise, I suppose the more signal may swamp the receiver. The receivers do have an AGC and the protocol (which is compatible with our Arduino HCWireless library btw) does send a preamble to give it time to adjust, but to what level it can handle I'm not sure. It would b...

This should hopefully fix it....



It's just the Line() and _Diff() functions that have been modified slightly if you just want to cut and paste them into your current file.

I'll hold off uploading this fix to the library thread for a while just in case..

Thanks. I can see the problem and it should be a quick fix. I'll post an update tomorrow as soon as I get chance to check it works.

Thanks for the feedback. We may at some point switch to a coiled wire instead of the spring antenna. This would give the option of being able to straighten it improve efficiency. I have actually done some tests on the modules with just a straight 1/4 wave piece of wire and as expected it does seem t...

It's to stop the possibility of a divide by zero error when calculating the step sizes. Although, I can see that it is making a test in the line function pointless so i'll take a look at it as soon as I get chance. If you have an example of how the line function is not working correctly I can take a...
