MICROCONTROLLER WITH OPTIMIZED ADC CONTROLLER |
摘要 |
<p>An analog-to-digital (ADC) controller is used in combination with a digital processor of a microcontroller to control the operation of capacitance measurements using the capacitive voltage division (CVD) method. The ADC controller handles the CVD measurement process instead of the digital processor having to run additional program steps for controlling charging and discharging of a capacitive touch sensor and sample and hold capacitor, then coupling these two capacitors together, and measuring the resulting voltage charge thereon in determining the capacitance thereof. The ADC controller may be programmable and its programmable parameters stored in registers.</p> |
