Thread: Displaying Values...

Hi all,
Im now doing a project using Silicon Lab C8051F226 in C language.. and the display is a external uOLED-96-G1..
I have did some coding and now its able to do the ADC.
lets say now i got the ADC value as '49'
the display i get is '1'. (because '49'dec='1'acii)
So how do i do to make the value to display '49'?
I had paste my coding bellow. pls help with the coding.
Thank you.
