Abstract: A general method of the real|time put out of multiplex PWM waves was introduced.Through the fixed time interrupt design in the software, the real|time put out of the PWM waves was met. The real|time output tolerance of the multi|lines PWM wave realized by software was analyzed, and the promotion ideas were also put out.
Key words: software; multiplex PWM waves; real|time put out
