is it no matter what pin is the column and what is the row?
I Have a set what I showed in #4362564 , but I don't know which pins are row and column or other, because it contain only chinese character .What pins have to solder from the DMS and HAT,CMS,TMS to shift reg?
In the MMjoy program I have to set up every buttons the correct row and coulumn place? Can I cange the buttons place or noumber after that I soldered in place ?


So the firmware install process is :
I plug the pro micro to PC
open device managger
touch twice the rst and grd
I write the com port noumber from device managger
Open the MMjoy program firm tab
once again touch the rst and grd on pro micro
and upload the firmware in 8 sec
