If you can see I have a shift register (3xcd4021b) in the handle. 6x5 pins and 5 pins in and 5 pins out on the board.
I just want to know, which buttom pins need to be connected on this pnael to mach the 5 wires(5v,GND,data,SCK,cs) which is go to the arduino board. And the TLE5010 wires can be common wires the samae pins except the data ? So the 5 wires come from the handle , and 2x6 wires from the TLE5010. but the GND, VCC is the same. so the total wires is 13 to go to the TQS base. but if I can connect another pins on the TLE5010 it can be save another pins. The DB15 connector is more then enough to bring the sign to the TQS.
But I don't know wich one can be use together. and what the connection order for the shift register to be the right place at the end.
