Practical C Programming

How it works...

We will define a variable, i, of the unsigned char type; a variable of the unsigned char type can store 256 bits, whereas that of a signed char can store only 128 bits. The i variable is assigned the HEX value of 0. We will set a while loop to execute infinitely. With every iteration of the while loop, the value of the i variable will increment by 1. Within the while loop, we will assign the value of the i variable, that is, 0, to port P3.

We will introduce a delay by using two nested for loops. Thereafter, we will execute a while loop again, incrementing the value of the i variable, making it 1. Again, we will assign the value of the i variable to port P3 for display. And, we will reintroduce some delay, followed by executing ...
