This procedure for the production of single-chip, duty cycle evenly spaced adjustable PWM generator. Adjustable duty cycle interval
For 0.1. Can be achieved with duty cycles of 0%, 10%, 20%...... 90% to 100% PWM waves. The frequency of this wave is fixed to 1KH (period 1000 microseconds). TX-1C learning the key board: S2---- duty and duty ratio reduction S3----
