This site https://www.costycnc.it/avr-hex-uploader is make manually by me and not have yet implemented all asm code ... so if want to help me are welcome!
This page was created for upload hex code to arduino nano ( for upload grbl firmware to arduino nano used in my costycnc foam cutter costycnc https://www.costycnc.it) ... but i added some functions (after tons of hours and google search and tests) that permit you not only upload your firmware to arduino but also create your small code in asm , compile it and upload to arduino!
So you can watch this first video tutorial https://youtu.be/0i8CgucF1Bg?si=npn7C0CtkzRj3GIi (is in italian but translated in english too) you will understand purpose of this site.
In few words ... you can compile asm code and upload to arduino nano only with this page.
In this mode you have many advantages :
-You can learn the base of microcontroller in generally and specially atmega328 architecture.
-You can learn the base of asm language (many are unknown now even to me!!!)
-You can create in this mode very small code.
-You can see in my tutorials practice example without download hudge programs.
And many other advantages which do not come to my mind now!
