Hi Trying. Hi Steve. Using the PWM module is a BIG improvement as each note will be perfectly on key. I converted some tunes into HPWM commands to play music on one of the PWM ports on a 16F818. The 818 can hold about 2 or 3 songs, the 16F819 can hold about 5 and a 16F88 that I used holds 8 different tunes. Below are 2 of them. If you want more volume, output the CCP1 pin to the gate of a FET. Source to ground and speaker from drain to B+. It will be painfully loud. I used a logic-level IRLZ44N at 3 Volts for this. Add the command CCP1CON = 0 and make the port LOW at the end of the song otherwise the FET may be left ON and kill the battery. CAUTION - writing songs and playing them on a PIC can be addicting! Be prepared to spend countless hours writing code.
