Hi all, I have run into a problem with my autopilot project. The autopilot altitude setting (offset 07D4) seems to be acting in a very strange way. It should be meters X 65536. So to send feet this should be; value to send = (alt in feet / 3.048) X 65536 In FS9 the value sent is close to what you want, usually just a few feet or even inches from the altitude I intended. Not a huge problem, but still anoying. In FSX no matter what value I send the alt sets to zero. Even if I read the value from FSX then send back exactly the same data it is set to zero feet. Anyone know what I'm doing wrong? Regards Bob.

Hi, As I said, I have not really researched the LUA yet. Better get reading. The offset, size, etc was sent to the PC from the microcontroller. Then my program passed this info to FSUIPC. Bob.

Hi Pete, Thank you for your reply. You have me thinking now. I'm sure I tried it with FS9, but I will give it another try. The program is still there on flightsim.com, if anyone is interested Just do a search for "Bob Edge". It is called FS Comm 1. What I liked about this is that it was universal, and could read or write any FSUIPC offset, without writing any code on the PC side. From what I gather (though I have not done much research yet) the LUA would need code for every offset you want to read or write. Anyway this has answered my question, thank you. Best regards Bob.

Hello, Years ago I wrota a small utility to read and write to / from flightsim via the serial port, using FSUIPC offsets, in my case using PIC microcontrollers. Unfortunatley it only works with FS2002 or below, and I have lost the source code, so I would have to start from scratch to do it again. I am not much of a PC programmer, so this is a daunting task. The way it worked was to send a serial message to the program in the form; Read or write, FSUIPC offset, size of variable, value to be written (if it is a write). My question is: Is there a similar tool out there that I could just install & use, and save myself alot of head scratching? Kind regards Bob...
