want to display 1,2,3,4 on four seven segemnt display connected to 8051 in such way that the display reads as "1234", but I am not able to write delay routine which refreshes the displays fast enough that our eyes is not able to catch it, kindly guide. using 12Mhz crystal.
125Hz sounds a bit low to me, considering that many people complain of flicker from standard fluorescent lamps - which is 100Hz over here. I once had a bunch of people looking at a 24*132 LED sign. all saw flicker at 75Hz some saw flicker at 100HZ none saw flicker at 120Hz
