Complex switch control system |
摘要 |
A complex switch control system including many switches, a switching voltage control circuit and a comparator is provided. The switching voltage control circuit converts an operating voltage into a switching voltage according to the states of the switches. The comparator compares the switching voltage with a reference voltage and outputs a switch state signal to a keyboard controller. A duty cycle of the switch state signal corresponds to the states of the switches. |
