Hi,
I m using the MSC 1210 Web Server board as published in the Elektor Magazine
I am using the uC/51 compiler and the sample program ELMET which measures a voltage
and communicates to the PC via a serial port. I am applying an 0 to 5 volts input between
AD0 and AGND1 and monitoring this voltage on the PC. It works perfectly from 0 to 2.5 volts
but as I increase the voltage above 2.5 volts the system continues to give an op of 2.5volts
all the way up to 5volts.
REF_OUT is connected to REF_IN+
REF_IN- is connected to AGND1, AGND2 and AINCOM
I would be grateful for any suggestion as I am not sure if the problemis in the software
or my connections
Thanks again
Regards
