" rel="nofollow - I need a custom app to control the RGB header on my AB350M Pro4 motherboard. I don't want to use an external RGB controller if there is already a nice controller on the MB present :) But i cannot find any documentation..... Is there any? I am running windows so any solution has to be windows compatible.

When you install ASRock's RGB software, the firmware file for the controller is in the App's BIN folder, with the .10 extension (in my case).

There you will also find the program to flash said firmware file, you will need to try and extract said firmware and go from there, the chances are slim and I don't think ASRock will provide source code, 2nd thing you can do is to try to unpack the app, and see how it sends the commands, my guess is the controller is connected using a UART/i2c not USB

But the manufacturers app is tiny and looks good in my opinion, it could use some tweaking for the UI to bring it in style, and fix a bug or two.

You can also set your desired RGB options in the UEFI, (I do it there)

You can also just copy the app after install and have it on a USB stick or secondary drive or folder and use it from there, its a standalone package no need for install actually.

EDIT: The 3rd option would be to search for the RGB controller on the motherboard and check the Model/SN on the inter-webs, that should provide at least a datasheet, then look in it what method of communication is used for sending the data from inside Windows, the manufacturer of the controller might provide the source code for it, and you can start from there.

Thanks for the info.

The applications seems to be created in Delphi, which is a pain to decompile and read for me :) I will try it though.

I might take a look at the chip on the MB but interfacing with chips over I2C under windows is new for me also. At least it will keep me busy for a few days :)

I am not sure if its i2c it might be a UART/SPI but I'm pretty sure its not USB :)

It might also be USB but somehow the port is hidden from the OS by the motherboards firmware.

You can try sending ASRock support a mail and see if they respond

Have a nice day

Just a heads up, ASRock released Polychrome RGB utility, currently only X470 motherboards support it, but if you install it you can see that the current X370 lineup is in the files but not working, upon install on my X370 ITX/ac the utility will list the board as unsuported, the utility is exactly the update that was needed to polish it up, hope they add support for current boards in the next update. You can check it out on the X470 boards page here http://www.asrock.com/mb/AMD/Fatal1ty%20X470%20Gaming%20K4/index.us.asp" rel="nofollow - http://www.asrock.com/mb/AMD/Fatal1ty%20X470%20Gaming%20K4/index.us.asp

I will check it out, sounds good.

Support was not very helpful... I got a link to the RGB utility :)
