Sorry i'm newbie here and like to learn.I had a problem here can anyone give a code/solution for this problem: Question: Connect a DIP switch to port B and 7 segment(common Cathode) to port C.Write a program to read input from DIP switch connected to port B and display them on each segment of the 7 segment as show below: DIP SWITCH 7 segment 0000 - all segments off 0001 - segment A on,others off 0010 - segment B on,others off 0011 - segment C on, others off 0100 - segment D on,others off 0101 - segment E on, others off 0110 - segment F on,others off 0111 - segment G on, others off 1000 - segment DP on,others off 1001 - all segment on
What hardware are you using? Have you any code samples you could work from? Adapting existing code is a lot easier than writing code from scratch. For example, do you have example code to read from some ports and write to others? What's the background to this; are you learning on your own, or are you on a course? If you read the switches simultaneously you can treat the resulting value as a number and use switch logic, e.g. Code: switch (read_DIP()) { case 0: write_7seg(0); break; case 1: write_7seg(1); break; // assumes segment A is at bit zero case 2: write_7seg(2); break; // assumes segment B is at bit 1 ...and so on. Code also assumes that setting a port bit to 1 will switch a segment on, but if you have inverting logic then of course you will need to invert this.
