I am trying to multiplex four seven segment display.
At 1 MHz (ATMega8 with default fuses), this results in 10^6 / 256 / 8 = ~500 calls per second. Each call, we turn off one display, reconfigure the segments to light up, and turn on the other display. This results in ~125 Hz refresh rate.
Will it be fine :?:
Also what do we have to consider related to Track Length on PCB to avoid Deghosting effect :?:
