Hi,
I'm making a project for my electronics studies.
The project contains 4× 4 keyboard 4×20 LCD - for UI.
The Micro Controller that in use is: Silicon Lab. C8051F020.
The user should enter 3 to 1 numbers to countdown -A Timer. The counting is on 3 7-seg display and not on the LCD.
During the counting-down on the LCD will be instruction like: Press A for hold B for stop C for reset and stuff like that.
My problem is to make the count. The last thing I want is to use the TIMER INT in the 8051.
My question is:
Is there any component which has built-in osc. and can count-down.
Something like 14553B but to countdown and to behave like a real timer.
Thnks
