Controlling 8 digital potentiometers using shift register to save pins
digPotCluster class is part of imbAVR.SynthControl library, in imbAVR.ArduinoSynth GitHub repository. It controls 8 digpots (MPC410-10) using shift register (74CH595N). Purpose of shift register is to reduce number of pins used for CS (chip selection): Normally, you would use 2 (SCLK, MOSI) + 8 (CS for each MPC410-10) = 10 pins Like this, you use…
