I've just wrote this code for my project (the 8x8 LED RGB Matrix) but this function seems not to work. I can't recognise the mistake...

CODE

void Serial_Out (char nbytes, unsigned long value) // nbytes = number of bytes to send; value = number to send
{
for (unsigned long i=0; i<nbytes*8; i++) // Repeats nbytes*8 times
{
short a;

a = 0!!(value & (1<<(nbytes*8-1))); // Shifts bit-by-bit (on the PORTB) the value to send
PORTB.F0 = a;
PORTB.F1 = 1; // Raising edge of the SERIAL CLOCK
PORTB.F1 = 0; // Falling edge of the SERIAL CLOCK -> now the bit has been shifted on the 74HC595 register
}

PORTB.F2 = 1; // Raising edge of the LATCH CLOCK
PORTB.F2 = 0; // Falling edge of the LATCH CLOCK -> now the 74HC595 outputs are "frozen" till the next LATCH CLOCK pulse comes
}

The errors are:

Invalid expression rgb_matrix_lib.h
; expected, but 'unsigned' found rgb_matrix_lib.h
Invalid expression rgb_matrix_lib.h
; expected, but 'long' found rgb_matrix_lib.h
Undeclared identifier 'i' in expression rgb_matrix_lib.h
')' expected, but ';' found rgb_matrix_lib.h
Undeclared identifier 'i' in expression rgb_matrix_lib.h
'}' expected ';' found rgb_matrix_lib.h
; expected, but '.' found rgb_matrix_lib.h
'PORTB' Identifier redefined rgb_matrix_lib.h
Specifier needed rgb_matrix_lib.h
Invalid declarator expected'(' or identifier rgb_matrix_lib.h
Internal error '' rgb_matrix_lib.h

PS: this code belongs to an header (.h) file, which is going to be implement on the main code:

CODE

#include "RGB_Matrix_lib.h"

void main()
{
...CODE...
}

Feel free to ask me if I've not been clear. Thanks again for your help

From the error messages you get I would think the precompiler does not like the taste of your .h file. Definitions, references and prototypes in .h files, and this and code in .c files.
