Show_PIO_PISO(wSubVendor,wSubDevice,wSubAux)
•
wSubVendor
[IN] the subVendor ID of the board to be determined
•
wSubDevice
[IN] the subDevice ID of the board to be determined
•
wSubAux
[IN] the subAux ID of the board to be determined
The
Show_PIO_PISO
function will display a text string to identify the special
subIDs. The text string is the same as that defined in PIO.H
A demo program is as follows:
