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.
why would you scan a display, are you trying to interface to some instrument by reading the display? 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.
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
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
