hi everyone,
Tell me which driver IC (like BCD to 7 segment latch) we should use to interface between AT89C51 (microcontroller) with 3 digit seven segment display (having 12 pin).
Also how I can do switching with transistors with single port of microcontroller simultaneously when other main programmed is also running in the microcontroller.

Hello,

Do you know the type of the display?
A link to the datasheet would help.
Is it CA or CC?

Greetings,
Bertus
