[HELP] Turn off or on led on PCB satan gh60

[Zeni]

Hi (sorry for my english it will be bad)
I begining to build a mechanical keyboard with the pcb satan gh60 and i bought some led, in fact i want to develop an algorithe who will predict the letter who will follow the previous for exemple if I click on T he can predict the H or an other letter  .
The prediction would manifest himself with the turn on of the led behind the letter (i want back litght) but i dont know if it's possible to manage the curent who pass in the led and if it's possible how do this things.

I hope you understand what i want to says if you don't ask me question.
Cordially Zeni

Hi Zeni, welcome to GH

Sorry to say you can't do that on the Satan (or any DIY board that I know of) - it's all keys lit or none, apart from the caps lock indicator which can be controlled on it's own.

It's an interesting idea but I think you would need a much more powerful chip with lots more memory to hold all that code and run what would be a very complicated algorithm, and it would still be wrong more often than not (unless you're a linguistic genius!)

Thanks to you I will take care of your advices and continue without this algorithme but I take the algorithme of a app who call "Dynamic keyboard" i will test on a best PCB after finish satan, could you propose me a good pcb on wich i could develop my mind?

thanks I'm just a little french who begin on hardware, i begin my studes in university of programmation and developement
