Can someone please suggest something for scanning a 6 digit 7 segment display? How can i assign a timer for doing the same? i m using msc1210y5.
BTW, I, personally believe that multiplexing of LEDs most often is totally misapplied. A string of shift registers (most can sink 20mA) will be cheaper, simpler and better when the segment current (as most often) is less than what a standard shift register can handle. With multiplexing you get currents that need to be switched by high end transistors (must carry 7 LEDs current) and who knows what else you need to add - some savings Erik
that does not require 'scanning' the display. if what you mean is 'multiplexing' then do a search at e.g. maxim and examples will be coming out of the woodwork. Erik
i m getting rs232 signal as output which corresponds to the displayed value on a scale. So waht i m making is another display which takes this signal as input and converts it into display value.
why would you scan a display, are you trying to interface to some instrument by reading the display? Erik
