Game Input MultipleXer

hello guys

am interested in this adapter and i want to make one but unfortunately i didn't find a usb to ttl converter in my area then i bought two arduino micro (ATmega32U4) but when i try to load the firmware to the adapter i get this message (avrdude butterfly_recv() programmer not responding)


can anyone help me with it

and can anyone send a photo of wiring the two arduino boards

hello again i've figured out how to build the firmware on the arduino but after that the arduino disconnects and shows the rx and tx led lights and nothing happen then.


i have tried to build the firmware on another micro board but i had the same result.

i tried to build an older firmware and the same problem occurs


i've changed the wires and nothing happen

and on the gimx launcher i get timeout message.


please help

Well, I don't think you can replace usb uart with arduino.

There was a way to do that some time ago but I don't know if it's still supported. @Matlo should know though.

Thanks guys
I found a frimware for the arduino to make just like usb to ttl converter on Malto's github page


But when i try to compile it i get many errors

I wish i could use it at the moment

This is a test firmware I made a while back. I will compile it for you but please understand I won't help further if it doesn't work.

Ok and thanks for that.


Yes i will not ask for help about it .

And if it doesn't work i will order a serial converter.

Many thanks.

There it is: https://github.com/matlo/USBtoSerial/releases/tag/v1.0

oh ,thanks bro

there is only one problem with the driver

it tells me (the third-party inf does not contain digital signature information)
