Microcontroller with optimized ADC controller .

摘要

Analog / digital (ADC) controller is used in conjunction with a digital processor of the microcontroller, by using the capacitive division (CVD) method, for controlling the operation of the capacitance measurement. ADC controller to control the charging and discharging of the capacitive touch sensor and the sample hold capacitor, then, these two capacitors together bound, when determining the capacitance, for measuring the voltage charging that occurs as a result according to which Instead of a digital processor it is necessary to perform additional program steps, I operate the CVD measurement process. ADC controller is a programmable, the programmable parameters may be stored in a register. .
