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 ?
