I'm facing a project, a seven-segment flip-flop screen, with 4 digits
I'm planning to flip each segment with a stepper (28byj-48), so 28 steppers
In addition, 28 button switches as stoppers, to set zero
By now I have tried with 74hc595 and it works fine, just testing with three steppers
Doing my math I can see I'll need about 20 74hc595, which I found a lot ...
Then, I found the max7219 and I wonder if anyone can point out if it is possible to use it for drive steppers? ... easily?
any help is grateful, thanks
