Detailed Description

This file synchronizes parameters between FreeBASIC, C and PASM source code.

This file is used in FreeBASIC, C and PASM source code to synchonize the positions and the size of parameter blocks, exchanged in DRam. It also contains the PRU message code numbers.

Since all the syntaxes have different markers for comments, we cannot use 'normal' comments here. We've to enclose the comment text in preprocessor blocks that never get parsed.

Note
We cannot use hexadecimal numbers here since syntaxes are different.

Macro Definition Documentation

#define PRUIO_IRPT   25

The interrupt number to use (25 => /dev/uio5, adapt constructor PruIo::PruIo() in case of changes).

Note that the interrupt channel and mask has to be adapted in file pruio.bi in case of any change here.
