Hello,
i am working right now on the minilogger product. My job is to convert it processor from c8051 controller to msp430.code for c8051 controller i have reffered & found a doubt on 7segment display code.i know its basic code but the programmer has added one file named VTEnglish.h that i dont understand.
here i m giving its snap shot.

for display i am using Total 8 digit display--> 4 digit as upper & 4 digit as lower display
kindly give your suggestions if any
thank u
