Writing to PMDG737NGX events

[Alpin-Flier]

Hi Pete

I have read a lot of documentation about FSUIPC. I tried also to understand LUA, LINDA, IPC a.s.o. and my brain got quite hot. To be honest, I lost a little bit the overview. Perhaps you can bring me on the right way again.

For MIP, MCP, EFIS and some pedestal of my PMDG737NGX homecockpit I want to use input/output boards from Simio Electronics. They use scpascal, offering a read from and a write to FSUIPC offsets. Reading data from PMDG should be no problem, because this works with FSUIPC offsets. But as I know writing to these offsets is of no use with PMDG. So I have to use customer control numbers to access PMDG events. But how can I transform a write to an FSUIPC offset from scpascal into a write to a PMDG customer control, with a parameter included?
Is it necessary to go via LUA and/or LINDA, that I don't understand up to now? Or should I use dummy offsets in FSUIPC, that can be written from scpascal and then converted somehow to customer control events?

It would be very helpful to get a practical exemple. Let me change the position of the AutobrakeSelector with its six positions.

#define THIRD_PARTY_EVENT_ID_MIN                0x00011000        // equals to 69632
#define    EVT_MPM_AUTOBRAKE_SELECTOR                (THIRD_PARTY_EVENT_ID_MIN + 460)

Therefore the customer control number is 70092, the parameter from 0 to 5.

Thanks in advance for for your most estimated help.

Check offset 3110 in the offsets list. There you write a parameter (first) in 3114 then the control number in 3110, and FSUIPC sends the control for you.

This works with ANY control numbers.

Hi Pete

Fantastic! You have already solved my problem. It works perfect, without any complex stuff.

Thank you again and best regards
