marti-gutierrez / ADC_on_AVR_microcontrollers

The following repository shows how to configure the AVR microcontroller registers to use the ADC (Analog Digital Converter), focusing on the Atmega328P (the one in the Arduino UNO), but can be used as a guide for other microcontrollers.

ADC on microcontrollers (Atmega328p) or Arduino UNO

This project is intended to show how the ADC (Analog Digital Converter) can be configured in the ASM and C languages of the AVR microcontroller architecture. This way we can use less memory capacity (Flash memory), compared to arduino, and understand what Arduino is doing when we use the function analogRead(pin)

The ATmega328p was chosen because it's the uC that is in the Arduino UNO and we can make use of its bootloader to not spend on expensive programmer.
