14E with power system

[SONGZIHAN]

The manual for the 14E board hardly mentions how to use it in the Power PMAC system. Is there a manual or reference material available specifically for using this card in the Power system?

See in the Power PMAC Users manual under the headings "Digital I/O Hardware and Configuration" and "Setting Up Parallel Data Position Inputs".

Thank you for your reply, the situation is that I follow the configuration in the manual and cannot read the position data. When I configure it as a normal IO, I can read the data, but it is active low

That would be adjusted with the “Inversion Control” structures of the ACC-14E. The structure “GateIo[i].Init.DataReg64[j]” (j = 0 to 5) sets the inversion-control value for each bit of the byte-wide register “GateIo[i].DataReg[j]”, whether the I/O point is used as an input or an output.

This is documented in the “Power PMAC User’s Manual” in the chapter “USING GENERAL PURPOSE DIGITAL I/O WITH POWER PMAC” starting on page 572. Specifically see the section “Software Configuration for Digital I/O Use” starting on page 578 under the subsection “UMAC Digital I/O Boards-> Inversion Control” on that same page.
