| unsigned int | gp3check (void) |
| Check the GP3 status. | |
| void | pause () |
| This is part of the optional demo program and just prompts the user to press enter to continue. | |
| int | main (int argc, char *argv[]) |
| The example main program. | |
It contains the portable code and an optional demo program. This library supports the GP3 I/O board (http://www.awce.com/gp3.htm)
gp3openport - Open a com port (returns -1 for error) gp3closeport - Close the com port gp3write - Write a byte to the serial port (returns 1 for success) gp3read - Read a byte from the serial port (returns byte or -1 for error) gp3ready - (Optional) read handshake from GP3 (return 1 for ready, 0 not ready)
To do this, compile in one of the other C files included with this distribution. For example: gp3linux.c, gp3cygwin.c, etc. You must compile and link only one of these files!
For more info on the other routines see the GP3 documentation http://www.awce.com/gp3.pdf

If DEMO is set, the library will include a test main. for normal compiles this should be set to 0. |
