I have to design a Human voice warning system for work, but only have a faint idea of what to do. The following I know for sure: 1) I have to use PIC16F84 (and program it using ASM, I have to use this chip!) 2) I have to use ISD2560P as the sound chip 3) There are to be 3 inputs which select 3 different recordings, there are to be switched on and off at which point it plays the warning, for example a water sensor, heat sensor... 4) The sound has to be amplified on a variable setting. 5) I do not need the speed or expense of a crystal oscillator so I want to use an RC oscillator running at about 100hertz. 6) The system must be powered by a battery 5v - 12v? Please, Anyone with any ideas of help, feel free to email me @ [email protected] with any diagrams. I know there are some really brainy people that could do this in 2 minutes so please help?? thanks Dale :)
