i have a couple of questions which need to be done in 2 hours. they are:
1) Write a program which Displays “47”, i.e. “4"on Digit 1 and “7” on Digit 2. Hint: the 4 and 7 only appear to display simultaneously -they are multiplexed (4, then 7, then 4,...).
2) Make an LED chaser. Turn on Digit 1 segments a,b,c,d,e,f in sequence, displaying each for exactly 160 ms, one at a time.
3) Up - Down Counter. The 2 digit count which is displayed is incremented with one push -button and decremented with the other. Sw1,2 = PD3,PB4
. Use masking techniques to read the inputs.
im using Atmel Studio. there are 2 seven seg displays, common anode.
kindly help please
