I have used FSUIPC for many years now, but am switching from Prepar3d to MSFS. I have 3 Joystick interfaces for Yoke's , rudder, brakes and Throttle. With FSUIPC6 no issue's, but with FSUIPC7 my Arduino Micro which connects the Throttle as a joystick cannot be calibrated within FSUIPC.7 I CAN use it directly when configuring the axis directly to MSFS. But i miss the calibration option of FSUIPC,; that's why i even bought FSUIPC7! Regards Roel

Hi, I searched the forum before I post and I saw that someone tried to communicate the Lua script and Arduino. We're sharing the same purposes. Let me say the problem I deal: For PMDG 737, I can control any button, switch in the simulation by sending data from Arduino to Lua script. Also, I have no problem to send data from Lua script to Arduino by using Lvar list in FSUIPC documents. However, I can't read the state of any warning light as Overheat Lights in the overhead panel. Only need to know, what should be the way of reading the state of lights in PMDG 737. If there is a small example or showing a way to go, I will be grateful 🙂

Hello, let me start by thanking Pete for his great work! :-) I am trying to replace the use of link2fs with lua-scripts. link2fs is great and it works but it seems to be no longer supported and while it finally seems to work with P3D V4 again, sooner or later it might cause problems. With the help of fess' and other examples online, I've written the following short script to adjust the QNH. I have verified using the link2fs traffic monitor that the arduino really sends "C25" and "C26" with linefeeds. The "Arduino_Data"-function also gets called, whenever I turn the rotary encoder. But that is as good as it gets. :-/ When I turn the rotary encoder slowly, nothing further happens. No datastring gets shown, nothing happens to the QNH. With the addition of the 50ms ipc.sleep before the datastring is read, the ipc.controls get executed when I turn the rotary encoder fast enough. (I assume that this happens when the com port buffer holds two Cxx-commands, because the datastring-readout that is shown in these case reads "C25C2", so one character is missing. When I am giving out the string length 'n', it is either 0, 5, 10 or 15. Something seems to quantize the datastring to multiples of 5. When I turn other encoders however, whose command is longer (e.g. "Y010"), n is 0, 6, 12, ... I've run out of ideas where the error might be and I'd be thankful for every suggetion where to look.
