it might get hairy doing this on linux, but you can always try. 1 option would be to use a atmel microntroller from the ATTINY series, they have ones insdie a soic8 package, with uart and if i remember corretcly, 2 PWM ports.
cheap and easy solution it'll cost around 2$ John Quoting Cyril Jaquier <[EMAIL PROTECTED]>: > Hi all, > > I need some PWM signals in order to control LCD backlight and buzzer.
