[PMDG event.offset is slower than MSFS event.offset]

I can do some testing here at some point to check this, but I am not sure when I will have time to do this as I  have quite a backlog at the moment...

John

Looking at all of the posts, a backlog is quite understandable.
No problem. 😉
My issue is not a show stopper.

Thanks again and thanks for continuing to support and develop FSUIPC.

[PMDG event.offset is slower than MSFS event.offset]

Trying to discover if this is a PMDG issue or an FSUIPC issue.
Hardware Setup:
I have an Arduino based Radio Stack as well as an Arduino based 737 MCP, my design, build, and code, utilizing LUA scripting through FSUIPC.
Both have push buttons, switches, rotary encoders with acceleration coded in, and 7 segment led displays.
Both were used in the past with P3D in the past with no issues.

With MSFS and the evolution of FSUIPC7, functionality has remained largely the same.

The Issue:
I have 7 segment led display modules on both panels.
In  my LUA script, a MSFS default offset like 0x0C4E (Course or OBS) gets its changes detected via event.offset. The value gets sent to the Arduino to change the corresponding 7 segment display. It happens fast and smooth with no apparent delay and you can see the digits change rapidly with out skipping updates.

With the PMDG 737 on MSFS, the MCP event.offsets for the IAS, HDG, ALT and VS have a lag to them.
If I turn the corresponding rotary encoders on my hardware MCP or use the mouse to turn the knobs inside MSFS, the displays inside MSFS update fast and look great. But when the event.offset reads the change and sends it back to the Arduino to update those displays, there is a lag that causes skipped digits and makes the displays wonky to utilize while attempting to dial precise numbers.
The Left CRS and Right CRS on the MCP utilize MSFS's default offsets and are not affected.
When the PMDG first came out and FSUIPC7 was in its early stages, PMDG had their MCP 7 segment displays accessible through LVARS.
The event.Lvar was laggy to the Arduino display as well. My hope was it would be faster with offsets.

NOTE: I never had this issue with P3D FSUIPC6 and the PMDG 737.

So the question:
Is this a result of FSUIPCs poll rate of the PMDG offsets or is it something in the PMDG code with their broadcast rate that delays outgoing data for a moment?

~Thanks in advance, Fess.

[Trim Set Control Bug and work around.]

P3Dv4.4 FSUIPC Registered 5.15

I'm building an Arduino based console with Trim wheels, elevator, rudder and aileron.
The wheels are on encoders that dial the trims. For rudder trim left and right, I use controls 66278 and 66279.
I have a push button on the encoder that I use to center the rudder trim using (Rudder Trim Set) control 66732 with a parameter of 0. 

ipc.control(66732,0) will only work once. After centering once, if you dial the trim left or right and then try to center again, the ipc.control(66732,0) will have no effect.
All of the "Trim Set" controls (Elevator, Aileron and Rudder) will not respond if the value of the parameter is equal to the last parameter sent.

I have found a work around by sending ipc.control(66732,1) followed by ipc.control(66732,0).

Cheers

Brilliant!

And Thanks.

[FSUIPC5 LUA event.com problem]

Pete,

Background: I have a home built Radio based on Arduino that uses a LUA script thru FSUIPC.  The LUA script worked fine with P3Dv3 FSUIPC4. The LUA script sends and receives data to the Arduino based Radio.

My Problem: "event.com" will not call its function when the script is used with P3Dv4 FSUIPC5v102.

The "event.offset" and "event.timer" function calls seem to work fine.

For those may be experiencing the same issue: I was able to make the script functional by using "event.timer" as a work around. I renamed the previous function block that I used for "event.com". I have "event.timer" call it every 50ms and do a "com.read" at the top of the function to check for incoming data from the Arduino.
