HEX file

[Lucmunoz]

Hello! Best regards from Chile.

Well this is not an issue at all... I would like to ask for help. Is there a way that you could upload a build hex file? I Don't know how to compile it.

I know it has to be made using WINAVR or withina avr-gcc environment that I don't know how to execute since I usually only work with arduino IDE.

Hope you can helpme or maybe explain me how to do it. Thanks so much Sr.

I would like to upload it to an ATMEGA16U2 on my Arduino Uno... But also, on a near future, i would like to buy standalone's atmegas16U2... could i upload this firmware just by USB (obiusly, building the circuit posted on your schematic). Mi idea is to use it to interface USB MIDI on a STM32F401. Thanks!

If you have a Linux OS, check that : https://github.com/TheKikGen/USBMidiKliK/wiki
If not, you can use a virtual machine.

Don't forget that you need to flash the 16U2 chip.

It is not the main ATmega328P itself (if you have a Uno). More generally, you absolutely need an Arduino with the 8U2/16U2 chip that manages USB. Some clones have CH340/341 dedicated usb interface not compatible with this project.

I recommend that you buy an USBASP interface (it is cheap, less than 10€).
