I am trying to use the second serial port and have been trying to use the example from http://www.keil.com/support/docs/2601.htm I get the error 67 undefined identifier. Any body know how I can get rid of this. Thanks
"it says I need XC16x.H which I dont have." it's on the free CD. (I don't use C166 - so that's where I found it). Have you tried the free download? "I have copied it" Shouldn't it just be part of the standard installation? You shouldn't need to be copying anything?
