And....it appears I need to add all my pins to the pinMode, right?
The SLR2016_D is an array that should hold the pin numbers of only the data pins for the display, not the other pins too. You dont need #defines for those data pins as well.In other words, my example code above just needed you to adjust the pin numbers, not add any more #defines or elements to the array.You dont need to #define the other pins (after all, what would you define them as?)Hope that anwers your questions. Your choice of Arduino pins should be fine.So does it work?
