hello : ) this is a question regarding max and arduino.
I have just set up a shift register circuit on a breadboard to control a 7 segment display. arduinos pins : 8, 11 and 12 are in use only, and it all works great. in max/msp I send 8 bit (0-255) numbers to the arduino which converts this to serial for the 595 shift registers.
The problem I am having, is that the sketch I obtained from a blog (link below), was only created to demonstrate the shift register concept, therefore all the other ins and outs on the arduino are not available for use.
I am wondering if it is possible to add code to the sketch (in the link), so that all the other pins can be used as well as the 3 pins assigned for the shift registers via serial?
I am very interested in this too, controlling multiple shift registers in a patch and using other pins too.
If someone could help me/us with this i would be so greatfull! I have been looking for this for a couple of days now and haven’t found a solution yet!
