Re: How to build music tone using 89s51?(play monophonic mus
Hi,
this might help
Circuit Cellar Magazine , Sept 2004
Microcontroller-Driven Sound Effects, by Praveen Deshpande & Prajakta Deshpande, p. 62
Code file attached with this message downloaded from circuit cellar ftp.
I'm currently using at89c2051 MCU.
Does anybody now if I can get an external interupt from other pin instead of the T1 or T0 pins. Especially for the edge triggered interupt.
Basically I need 3 pins for external interupt which point to INT0 sub routine.
Thank you for the help.
