Analog Comparator Atmega328p. It is designed by 8 bit cmos technology and rsic cpu which enhance its performance and its power efficiency get improved by auto sleeps and internal temperature sensor. I am trying to find some information on how to use the analog comparator on an atmega328 to detect when an analog pin has reached a certain voltage 3 16 volts.
In atmega16 nine pins are available to connect negative input of comparator. The analog comparator is a crazy little thing. Avr based atmega16 atmega32 has an on chip analog comparator which compares two input analog voltage signals and gives which is higher in between them.
First seting the acbg analog comparator bandgap select bit to one tells the atmega328 to apply its own internal bandgap voltage about 1 1v to the positive input of the comparator.
The negative input is analog pin 7 on the arduino. I am trying to find some information on how to use the analog comparator on an atmega328 to detect when an analog pin has reached a certain voltage 3 16 volts. The analog comparator has been ignored in the arduino library software. The analog comparator in arduino nano every s atmega4809 is more versatile and has more features.
