My hardware is per attached. I need to construct an address decoding circuitry on an ISA adapter card for decoding the I?O devices. The I/O devices consist of five 7-segment LEDs, one 16-segment LED and eight push buttons. The 16-bit data bus is for data transfer, and I/O map for I?O devices. The I/O address for 16-segment LED is 300H-301H and I/O address for 5 x 7 segment LEDS is 302H-306H and I/O address for 8 x push button is 307H (D8-D15)
I need to do a auntomatic incremental counter ( how sould the program be like for this part)? A 5 digit random number shall be displayed on the five 7 -segnebt LEDs and automtically incremented by one every second whenever pushbutton 3 is pressed. Any one can advise me on this part's programming? Thanks!!!
