I switched from IAR to Crossworks and I'm trying to get my code to
compile. My first issue is with the below code

volatile union
{
unsigned const char P2IN; /* Port 2 Input */
struct
{
unsigned const int P2IN_0 : 1;
unsigned const int P2IN_1 : 1;
unsigned const int P2IN_2 : 1;
unsigned const int P2IN_3 : 1;
unsigned const int P2IN_4 : 1;
unsigned const int P2IN_5 : 1;
unsigned const int P2IN_6 : 1;
unsigned const int P2IN_7 : 1;
} P2IN_bit;
} @ 0x0028;

#define Sw1 P2IN_bit.P2IN_0
#define Sw2 P2IN_bit.P2IN_1
#define Sw3 P2IN_bit.P2IN_2
#define P2_IN_3 P2IN_bit.P2IN_3
#define P2_IN_4 P2IN_bit.P2IN_4
#define P2_IN_5 P2IN_bit.P2IN_5
#define P2_IN_6 P2IN_bit.P2IN_6
#define P2_IN_7 P2IN_bit.P2IN_7
Crossworks is giving me the following errors:
empty declaration
found '...', expecting ';'
unrecognised declaration

Am I missing a syntax issue or can I not define my port bits in this
manner?

Thank you for any help in advance! Start a New Thread

2 things, named the structure after struct keyword and before the {, secondly
crossworks does not support anonymous unions that is a C++ feature..

do a bit of searching, there are several examples on how to bit adress ports
including one I posted a month or 2 ago..
