I have been using ARM for a few days and downloaded the file lpc2100_intsio.zip from the Keil file download section. I have a question. The program compiles and runs fine in THUMB mode, but when I switch the Target options to ARM mode the compiler generates 2x errors. Error L104 Multiple public definitions of putchar?A and _getkey?A and and 1x warning L23 unresolved external symbols.
For the life of me I cannot figure how to fix the problem. I would greatly appreciate if someone can enlighten me!
Also I see that it should be possible to change the serial window 1,2 or 3 to look at the Com1 port (to save me running hyperterminal). I see the information about using the ASSIGN command. But I dont get what I have to do, I have tried doing this in the start-run-cmd window of windows and it keeps giving various errors. Can someone provide a "dummies guide" as to how to do this - thanks
