WideClient, Lua, and AP_ALT_VAR

Is there anything unusual about the AP_ALT_VAR_INC/DEC offsets?

(Surely not ... but)

GoFLight GF46 connected to WideClient computer with controls and display run by my lua code on the WideClient computer. The pushbutton changes what is displayed and the rotary knob changes the value (or when pressed and rotated, changes a related offset). This all works except for access to the autopilot altitude offsets. (The fast offsets work as expected). Data is sent to FSX but nothing changes. I've included below a chunk of the WideServer log and the WideClient log as well as the two lua tables that determine what control offsets go with what and what is read and then displayed. Since everything in the table works as desired except the two offsets at 65892/3, I'm both perplexed and wondering where to look for my mistake.

In the logs below, I start on the VS (Autopilot vertical speed) and rotate the knob twice to the right and then press it and rotate once more to the right. This has the desired effect of increasing the vertical speed by 100 twice and then by 1000, just as one expects from the descriptions of the offsets. I then press the button to switch to the ALT display (which reads correctly) and repeat ... twice clockwise and then once while pressed. As can be seen from the logs, when the knob is rotated for ALT, the correct offset information and param value (=1) is sent, but unlike the other instances, nothing is returned. (For VS, VS FAST and ALT FAST, everything works).

Puzzled.

Is there anything unusual about the AP_ALT_VAR_INC/DEC offsets?

There's no such thing as those offsets -- they are FS controls, not values in FSUIPC offsets.

GoFLight GF46 connected to WideClient computer with controls and display run by my lua code on the WideClient computer. The pushbutton changes what is displayed and the rotary knob changes the value (or when pressed and rotated, changes a related offset). This all works except for access to the autopilot altitude offsets. (The fast offsets work as expected). Data is sent to FSX but nothing changes. I've included below a chunk of the WideServer log and the WideClient log as well as the two lua tables that determine what control offsets go with what and what is read and then displayed. Since everything in the table works as desired except the two offsets at 65892/3, I'm both perplexed and wondering where to look for my mistake.

65892 and 3 refer to FS controls, just like those you can assign in FS itself, or in the dropdowns in FSUIPC. They are not "offsets", which are the hexadecimal addresses of values in the FSUIPC data and range from 0x0000 to 0xFFFF (decimal 65535 max).

As can be seen from the logs, when the knob is rotated for ALT, the correct offset information and param value (=1) is sent

FS INC and DEC controls do not take any parameter in any case. They just do increments and decrements. You might as well just send the 4 bytes for 3110.

Puzzled.

I cannot tell what is going on from the information you supply. Please use FSUIPC logging so we can see what's happening in FS. Enable event logging. You should also set offset 3110 as a "U32" for monitoring on the right-hand side of the Logging tab. Don't worry about the parameter at 3114 as that's not used in the INC/DEC controls in any case.

Pete

Yes, that was just stupid of me. Of course they are controls, written using ipc.control()

FS INC and DEC controls do not take any parameter in any case. They just do increments and decrements. You might as well just send the 4 bytes for 3110.

That fixed the problem. Instead of ipc.control(65892, 1) where the "1" value from the event call and which is sometimes 2 or more (fast knob turn), I changed as you suggested to ipc.control(65892) and the problem went away. Permanently, I trust.

Hmm. Strange that a parameter I though would be ignored actually does something. That's interesting. Quite often the parameters are used to address different copies, but I can't imaging there being another AP altitude register. Maybe a bug in SimConnect.
