Hi Andy >Have you read the PWM examples on Scott Dattalo's pages? >http://www.dattalo.com I have now ;-] A few examples on the pwm and one section on up to 8 pwm streams. Looks good. However the bit of text at the first page..... "If the pic code gave you a headache, this will give you a migraine" Makes me nervous ;-] Thanks!
