Situation: You want to include a timer interrupt service routine in an assembly language program for an AVR-based Arduino. The program will ... I keep both of them open, along with the Data Sheet for ...

b. -Os in simple words, Optimize the output file for Size. c. DF_CPU= defines the MCU system clock which is indeed the 16MHz for the Arduino-Uno. d. -mmcu=atmega328p pretty straightworward, defines ...

In this post, I am going to probe the components and compatibility of a cheapest Arduino Uno Wi-Fi board you can buy for your IoT projects. The UNO R3+WiFi (ATmega328P+ESP8266) board is an unofficial ...

Here we will be looking at an Arduino Uno as an example. I have marked the main components/parts on a UNO in the image below. In the UNO board, the main component is the ATMega328P. It is the heart of ...

I’ve been using the Arduino Uno board for quite some time, and I’ve always wondered what it would take to get the ATmega328P (the original chip used on the older Uno boards) working completely on its ...

An Arduino Uno is just an AVR development board ... an “Arduino” and not just an AVR is the bootloader. Thus: An Atmega328P is an AVR processor. An Atmega328P with the Arduino bootloader ...

The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.
