I am in dire need of someone to please help me or give me code for a voltage meter programmed in MicroC for the 8051 Bipom board. I have posted already and appreciate the help but am still stuck. Please look over code and tell me or fix whats wrong or provide me with code that will work. Many thanks in advance.
