Pulse counter with two lines with 4 digits each line

[fjpompeo]

Need a kind diferent pulse counter. It may have a PIC or an AVR or even discrete CMOS/TTL ics. It must have two lines with 4 digits each line, one for total counting and other with sub total. Each line must have a separe reset or the reset for subtotal desn't clear the total counting line but when you reset total both lines are cleared. When it starts counting both lines count toghether but after the first sub-total reset, second line will star from zero but total line will increase last counting plus actual counting.

Thanks,

Fernando

Re: Pulse counter

Hi,
Doesn't look too complicate. You can do it with an cheap atmel 89c2051 for example. If you need tools for small sized code development you can use keil demo from www.keil.com .
