hi all,

Im developing a controller interface for software in max msp based on the sugarcube controller.

Ive used 4 RGB LED rotary encoders and multiplexed the LED's together with 2 HC595 chips e.g LED 1 R=Q0 G=Q1 B= Q2 etc etc.

Im able to make all the leds light up with 595 test code but need to be able to control them with serial messages to get the specific colours when buttons are pressed.

This is where my knowledge is limited and i'm finding it confusing to figure out.

Any help or information regarding decoding binary data or using serial data to control things in max would be great


As i understand with the HC165 i can read the binary serial data output to work out which serial data message is which button being pressed. i then use this serial data in max msp to control parameters.

Serial data input i can grasp but data output is slightly confusing.
