ABSTRACT:
A method for generating multiple high-resolution PWM signals in which software interrupts are introduced at predetermined intervals to generate multiple high-resolution PWM signals from a conventional microprocessor. The software determines the purpose of the interrupt in an interrupt subroutine. An interrupt occurs when a compare register equals the timer. Another interrupt occurs when the timer overflows. The interrupts are the key to generating the multiple high-resolution PWM signals.
