i need o to 999 hour seven segment based count up meter circuit and hex files for my generator.
please any body help my to design its hardware and hex also.
 
oh sir
i want to made it personaly

There are 3 main tasks to do:

1. Make a timer that times out in one hour.
2. Make a counter that counts 0-999
3. Make outputs to the I/O pins and interface to 7-segment disp.

3a. Simple - use 21 IO pins and connect 3x 7 seg directly.
3b. Hard - use 10 IO pins and multiplex 3x 7 seg disp.

Have you decided which MCU ?
