> The question 1. >How to use the regime PWM? >Have at whom the examples of programs with uses PWM? I have used the PWM module in the PIC16C73/74 for several different items. The microchip app notes are rather useful. Visit the Microchip web site (http://www.microchip.com) and look for the PWM notes. Some PWM things reference the 17C4x - don't get those, they are very confusing. If you have any specific questions, I would be happy to help you. >Who is knows the format of files RTF and from it to read?
