An array will work, but a 'define', can't have a size like this.
Square brackets are not allowed in a define. The square brackets in the manual entry for this (on some manuals), are for the 'optional' part.
#define is a text macro substitution language, not a variable declaration. #define is also not a string.
| Code: |
int16 pins[8] = {PIN_E5,PIN_J8,PIN_J11,PIN_J14,PIN_J0,PIN_J4,PIN_J7,PIN_E2} ;
|
will work, and you can then use 'pins[0]' and pins[3] etc., as pin numbers.
or
| Code: |
#define pinlist PIN_E5,PIN_J8,PIN_J11,PIN_J14,PIN_J0,PIN_J4,PIN_J7,PIN_E2
int16 pins[8] = {pinlist} ;
|
However also remember that pin functions involving variables are much bulkier and slower than those using constants. |
