Play modules soundtracks on a LGT8F32p using :
- the analog output DAC0 on pin 4 ;
- a FastPWM audio output on pin 3 (it will also work on real ATmega328p @ 16MHz) ;
- an external 6bits DAC on pins A0 to A5 (it also will work on SimulIDE ).
This is a quick and dirty port of pocketmod to LGT8F328p.
It is limited to 4 channels .MOD modules, with 15 instruments max.
The audio is outputed through the digital to analog output (DAC0 on pin 4) to which you may want to connect an audio amplifier. It can also be outputed on pin 3 as FastPWM (62kHz @ 32MHz or 31kHz @ 16MHz), to which you may want to add a 100 Ohms resistor in serie with a 8 Ohms speaker.
The sketch is designed to adapt automatically to the F_CPU, and at 32MHz, it will play at ~12KHz sample rate.
Several modules are included as a demo for test and debug purpose. Their original authors can be retreived using the link into the .txt files, into the /mods directory.
If you want to play a tune of your choice, it has to be .MOD, 4 channels, and small ennough to fit into the flash.
The module file has to be converted from binary to an 8bits array in a C header (I don't rememebr how I did that ...), and then it is compiled with the rest of the sketch and is stored as PROGMEM.
