The easy way is to use the sprintf() function

Use the sprintf() function to convert a 16-bit integer to an ASCII string.
After executing the following program, the contents of the buffer[]
array will be:

buffer[0] = '1'
buffer[1] = '2'
buffer[2] = '3'
buffer[3] = '4'
buffer[4] = 0

The use of single quotes around a number means it's an ASCII value.
The final 0 in buffer location 4, is the string terminator. It is not ASCII.

main()
{
char buffer[6]; // Allow enough room for 5 digits, plus the string terminator.
int16 value;

value = 1234;

sprintf(buffer, "%lu", value);

while(1);
}

Mabuhay!

I hope this code snippet is of great help to you. This is based on the ASCII table of characters with their equivalent hex value.
