The Realization of Dual-Channel PWM Signal Based on C8051F020 MCU
In the power balance of energy between single cells control and intelligent robot motor control need to use dual PWM signal, for use C8051F020 MCU multi-channel 12-bit ADC converter to convert the input signal of each group and compare ADC0 conversion value, And, the result of ADC0’s each channel gives Programmable Counter Array PCA0 to form of controlled dual PWM signal, and it’s frequency can be set. At the same time coming into being in pair of road PWM signals, use window detector ADC0 to realize reality measuring value surpassing range alarm and protection.
