Hello,
I am trying to create a countdown timer using PIC16f690, i ll use 3 seven-segment displays. The first one is for counting hours (max 9 hours) and the other two i would like to count the minutes. In my program i am storing the hours in a register (HOURS) and the minutes in the MINUTES register when i want to display the contents i use 4511 BCD to seven segment decoder. Using this approach i can solve the problem for the hours but i cant display the minutes above 9 minutes. Is there any IC that decode BCD to dual seven segment display?
Thank you in advance
