PIC frequency divide

Hi,

Could someone possible write a small bit of assembler code for me that will divide a 32.768Khz crystal (attached to a PIC 16F627) into frequencies like 330hz.

Also could you possible tell me how to change the code to divide it down into other frequencies. (all under 1Khz)

Thanks for all your help in this AMAZING forum

You can use the 16F627 PWM for tone output for your piano.
PIC PWM Calculator & Code Generator

Hi,

Thanks for that, but what PWM do i need?

Cheers

PWM is hardware a pulse generator designed for motor control built into many PICs including the 16F627. Once set it simply runs on its own till changed or stopped.
For musical tones just select 50% as your duty cycle.

Read the CCP module info in the datasheet.
