hi i want to design a count down display using avr ,the counter should produce a interrupt signal or indication when the count reached at zero , the count length has to be variable , so that it can be changed as per requirement . am using code vision avr compiler , can anyone help me in this project ? .
i want the source code design , the counter should have the following
1. the count should start from the number specified by the 3 bit input to the micro controller
2. the count starts only when the enable pin is high
i want to design it in codevision avr compiler , when i am trying to do this tutorials for codevision avr is not available for this
one ,if you can help me to design the program that will be great
3 bit = 2^3 = 8 values. Do you mean 3 digit ? like 0 to 999 ? You didn't answer whether you are using 7 Segment display or LCD. If 7 Segment display (SSD) then is it Common Cathode (CC) or Common Anode (CA) ? I will write code if you answer my questions.
