I am just starting with the PEC in an XC167. Can someone tell me how to output a string that is not a 'const' string? The example PEC code from Keil works - code is posted here: http://www.keil.com/support/docs/688.htm - 6.2K - Jul 15, 2005 If the 'const' modifier is removed, the output is garbage. How do I modify the string? Also, what magic is the const modifier doing? Any help is welcome. Without the const modifier, maybe the string is optimized out?
