Hi all, I am using DM134B LED driver for displaying numbers in 7 segment driver. I have written code in AVR studio 4 and I am sure that the that is ok because the serial output port present in DM134B outputs the data in sent through serial input. The circuit that I am using is the one from the datasheet provided by DM134B but there is no port output in any of the pins so can anyone tell what is the problem ?
