-This paper introduces a kind of method of DC —motor speed modification based on PWM theory by
the SCM．Showing some relative knowledge upon the DC—motor timing，the basic theory and the way to implement．
And it emphasizes on the way for carrying out PW M signals based on MCS一5 1．This paper still provides a method
for modifying the speed of DC—motor by way of taking count of data and time delay by software．It offers a sort of
eficient method for the DC motor speed—controlling system Platform: |
