Hello,
A few days before I built a box (Micro Pro and MMjoy2) with switches and buttons that use 4021 registers. Everything works fine until I connected two encoders. Due to the fact that there was no free pins in 4021, the encoders were directly connected to the Arduino Mirco Pro (encoder No. 1: rows-B5, columns-E6, B4; encoder No. 2: rows-D7, columns-D4, C6 ). The problem turned out that the encoders "took over" previously assigned to the "H / W. Buttons" switches (1-2 and 7-8 ). As a result, the whole assignment of buttons in MMjoy2 do not work correctly. Is there any software way to change it?
