Hello,
   Does anyone have any C code that actually reads the MCB2130 
hardware ADC on AIN1 (the potentiometer tied to P0.28) they would be 
willing to share?  I have tried the Keil code, the Hitex example
code, manipulating bit values, etc., for most of 2 days and cannot 
get ADC to return a value that I can display via COM1 on the 
MCB2130.  The code I have been exploring uses hardware continuous 
conversions rather that software interrupt driven conversions.  I 
really thought the hardware conversion would be easier to implement 
than the software.
   I verified that the voltage varies at P0.28 with a DMM when I 
adjust the pot, but I get nothing but 0 from AD0DR.  
   I contacted Keil via telephone and didn't get much help (other
than suggesting I run it in the simulator -- more stuff to learn).  
I also sent my source code to their support center, but have not 
received a response.
   Any suggestions (or simple code hints) will be greatly 
appreciated.
