Hello,
I have a newbie question. I'm trying to find CMOS or circuit that using 6 Micro controller pins I need to control 64 transistors. These transistors will driver 64 digits (7-seg LEDs).
My thinking is to use 6 BCD decoder/multipler (if one available) to control these 64 digits (transistors). If that is not possible, how can I control 64 digits with the least amount of PIC pins?
Can someone help me please?
Thanks
