Save led, piezo to "listen to" the tape

[juri74]

Could be possible to implement: 1) a red led that will lit when saving in progress? 2) a piezo that play the music? :D for ability to listen loading/saving maybe turnable on/off in Options menu ;) i splitted the pause from led & piezo, since there is an hardware solution is better use it to save program space.. however a led connected to D13 (if isn't used for other things) could be useful and shouldn't use much program memory i think (D13 is already connected to a led on almost all arduinos) :)

There are hardware solutions available for something similar to the piezo via ozayturay's board (provides LEDs that are transistor driven for SAVE / LOAD). Please could you break this up into separate issues? The save LED could be handled fairly easily via code (just add an output) etc. so tracking these separately is better.

The save LED function will be added with the release of the 1.7 hardware and controlled via software, I'm just waiting for the boards so that I can verify this. The piezo switching is another story and would require hard ware support so I don't think this is going to happen.

Thank you for update, i have an idea on how doing piezo support with minimal effort, i think arduino should provide an "activation signal" then it will be ANDed with the tape read or tape write signal, finally the output pin of the AND chip will drive a piezo. i have to wait the 1.7 board too and some parts for testing :) i lost track of available pins, is there one free? thanks Juri

Save LED support has been added to the code base, piezo is hardware supported on 1.7.
