A LED Onboard Blink Asm Avr for Atmega328p Arduino Nano With the TIMER0 Interrupt Costycnc

The html page https://www.costycnc.it/avr1 with avr asm examples from where you can compile and send to arduino the code! 

All in one page ... not need compiler or programmer ... for begin secrets of asm arduino need only an arduino nano, a usb cable and a computer.

 Here https://store.arduino.cc/products/arduino-nano can buy arduino nano from official store or from internet https://www.google.com/search?q=arduino+nano .

 I hope that my page will increase your curiosity about mictrocontrollers specially atmega328p that is more popular and more sell in the world!!! 

 So a valid reason to begin and knowing this most popular microcontroller!!!

Arduino nano

Usb cable

Computer

You can use https://www.costycnc.it/avr1 to compile and send to arduino!

When click button "Assemble Timer0 interrupt" the code will go in first code box below and will be ready to compile and send to arduino.

Now only click "Arduino nano with old (or new) bootloader" dipends of arduino if you have ...

Select port and upload ... after upload you can see the led onboard blinking!!! The code make blinking led after few seconds.

You can decrease blinking interval modifing line "cpi r17,255 ; Compare r17 with 255"

modify 255 ... put lower value , assemble ... upload and wil see that led blink more fast!!!

See also another examples of the page (actually a this date 03/03/2024 undocumented !!! but i hope hat will explain in future all examples and will add more).

Also i save the html code with javasctipt file here https://github.com/costycnc/avr-asm-atmega328p-low-programming-and-understand-functions-costycnc where will find all versions.
