Direct writing to GX5282

Hi all,

I am looking for a solution to control 2 GX5282 cards at the same time (one card with TTL/LVDS, the other card with LVDS). What would be the best way to accomplish this? Ideally direct writing to the channel (static mode) is what I want but I can't find any example doing this (LabVIEW). Can anyone share the code to do this?

Thanks in advance.

Each GX5282 card has two connectors J1 (TTL) and J2 (can be configuired as LVDS). Each connector has 32 channels 4 groups of 8 channels. Groups can be configuired as Input or Output. The TTL/LVDS is really depends where you connect your UUT pins. if you connect to J1 yoiu get TTL, J2 LVDS. So there should be no issue to achive what you need.

For an example to program static pins see the DioWriteIoPinsValue, DioReadIoPinsValue in the function refrence. These are pretty simple to use.

Re: Direct writing to GX5282

Thanks for the reply. I guess I didn't clearly state what I need. I need to control both TTL (J1) and LVDS (J2) from the master board, LVDS (J2) from the slave board, using direct writing method. Now I see the direct r/w method but how can I control both J1 and J2 at the same time? Thanks again.

Solution Available

For input use the DioSetupInputInterface() function to configure if J1 or J2 are used.
For output there is nothin to configure since both pins J1/J2 are used.

See also DioSetupIOConfiguration() for input/output and group configuration.
