hi Pete, I have test with the [Auto] section and it's ok! Thank you very much, Aurelien

I completely agree with you, Pete, I stubborn this weekend and accumulated mistakes. After a 48-hour break, I leaned over the problem, and I started all over again. It's good, tonight, my event.lvar scripts work, for all the gauges of the cessna cockpit. 😉 The only thing that does not happen is the launch of the script independently. To do this, I assigned a switch. Thank you for your time. Aurelien

Hi Pete, I will try to answer your questions: / I had a RPM.Lua folder because yesterday, my script "event.Lvar" for RPM worked only on a separate folder. / For the ï character, I had rewrited the script, many times, change his name (C172gauges instead of RMP.lua), but nothing work... / I had check the value in the offset, and there was correct. Now, it's worse... the C172gauges script is not used by FSUIPC. it does not appear in the log file, however, he is mentioned in the FSUIPC.ini... I ask google concerning the error "unexpected symbol near 'ï' ", it could come from the text editor, wich could put hidden special characters. I use Notepad++, and the coding use is UTF-8 (without BOM). All this makes me waste a lot of time...and your tim too..., while finally the script with the form "while 1 do ... ipc.readLvar, ipc.write..." work perfectly... How is the use of "event" better for you? Because, interfacing a cessna, I finally have not a lot of variable to interface, it would not be enough with this form of script? There is some "limits"? thank you for your help. Sorry if I'm stuck. It's incomprehensible for me, but it worked yesterday morning, but it's impossible to redo this "event.Lvar" Aurelien

I don't know why, but I have somethig like this now in the FSUIPC5.log folder, and I think this is want you expect Pete!

Thanks Pete, So, yes I have found the Log Lvar.lua, anyway I have define ctrl+F2 for log lua log Lvar and ctrl+F3 for lua kill all to stop the log. When I use these, I have this file: (I cut the middle, this is all the Lvar as you know, thas why I did not put it just before. I put the begining and the end, unless you want it entirely?)

I still have a problem... The code is ok, and work great for RPM. So I put a second Lvar, on the same script: -- definition des fonctions function RPM (Lvarname,value) ipc.writeUW(0x66C0,value) end function VSI (Lvarname,value) ipc.writeSW(0x66C3,value) end -- lecture des Lvar RPM ("L:Eng1_RPM",ipc.readLvar("L:Eng1_RPM")) VSI ("L:VerticalSpeed",ipc.readLvar("L:VerticalSpeed")) -- surveillance des changements de valeur event.Lvar("L:Eng1_RPM",100,"RPM") event.Lvar("L:VerticalSpeed",100,"VSI") but there is no value for vertical speed... I tried to do one separate script for vertical speed, but it doesn't work too... it's weird. Do you have any idea? Thank you Aurelien

It's OK, I finded the good script and removed everything before. This is my script; and it's loaded as soon as RPM value change! thanks! function RPM (Lvarname,value) ipc.writeUW(0x66C0,value) end RPM ("Eng1_RPM",ipc.readLvar("Eng1_RPM")) event.Lvar("Eng1_RPM",100,"RPM") 😉

Sorry Pete but I dont' understand; I made it very clear the Lvar between the () after "event.Lvar". If I understand correctly, it is not enough to just replace ipc.readLvar by event.Lvar? I tried with "function", with thirs code, but it doesn't work function(Eng1_RPM, value) event.Lvar("L:Eng1_RPM", 100, Eng1_RPM) ipc.writeUW(0x66c0, Eng1_RPM) end

Hi John, I tried to use the library "event.Lvar()" but there is nothing when Lvar change, even if I switch some thing like battery. I tried with this code: while 1 do RPM = event.Lvar("L:Eng1_RPM") ipc.writeUW(0x66c1, RPM) ipc.sleep(100) IAS = event.Lvar("L:AirspeedIndicatedNeedle") ipc.writeUB(0x66c0, IAS) ipc.sleep(100) end thank you, Regards Aurelien

Thank you, I had just found the mistake! I had the idea to be one as you suggested, and it works! ... Now I will look with "event.Lvar ()" function Regards, Aurelien

Hi Pete, I have progressed! First, I modified the script, for IAS, 8 bit, so ipc.writeUB, on offset 66c0. Test: all right, it works. Next, I added the script for RPM, 16 bit, so ipc.writeUW, on offset 66c1; Test: negatif. Always ok for the IAS, but no value receive for the RPM. This is the script: -- test battery battery = ipc.readUB(0x3340) if battery > 0 then ipc.writeLvar("L:Battery1Switch",1) else ipc.writeLvar("L:Battery1Switch",0) end -- test IAS while 1 do IAS = ipc.readLvar("L:AirspeedIndicatedNeedle") ipc.writeUB(0x66c0, IAS) ipc.sleep(100) end -- test RPM while 1 do RPM = ipc.readLvar("L:Eng1_RPM") ipc.writeUW(0x66c1, RPM) ipc.sleep(100) end So I decided to switch the positions of these scripts: and that is the problem!!: now, I haved value for RPM on 66c1, but no for IAS on 66c0! the script: -- test battery battery = ipc.readUB(0x3340) if battery > 0 then ipc.writeLvar("L:Battery1Switch",1) else ipc.writeLvar("L:Battery1Switch",0) end -- test RPM while 1 do RPM = ipc.readLvar("L:Eng1_RPM") ipc.writeUW(0x66c1, RPM) ipc.sleep(100) end -- test IAS while 1 do IAS = ipc.readLvar("L:AirspeedIndicatedNeedle") ipc.writeUB(0x66c0, IAS) ipc.sleep(100) end So I have understood that only the first script is reading in the script! After, I have tried to do 2 script .lua: on first for battery (3340) and IAS (66c0) on second for alternator (3344) and RPM (66c1) => and now, it works for the two gauges i same time! Because there is on 2 differents script! Do you know if it's possible to write theses script on the same .lua text? Maybe I forgot something between the two script? Thank you for your help, Aurelien

Oh sorry... I mixed every thing between decimal and binary!!... Yes you are right, speed value is rounded. Mobiflight use the rounded value, so for the speed, 0 to ~ 200 knots wich gives in decimal 0 to 11001000 so 8 bit, unsigned. So if I use the offset 66c0, for the airspeed gauge, wich use 8 bit=1 byte, the next free offset should be... 66c0 + 1 byte = 66c1= the next free offset wich can be use. That's all right? Thank you, Aurelien

Thank you Pete. I start to see more clearly, I started again from the beginning today. I used the offsets you told me. So, first, I checked the Lvar list in real time. This is a part of it: 3528031 LUA.1: L:Eng1_RPM=1616.0072558023 For the RPM, we have 14 figures, only positive. So, logically, it's on a 16bit, and usigned, so it will be "writeUW" in the script. I tried with this code, on offset 66c0. And it's ok!!🤩 while 1 do RPM = ipc.readLvar("L:Eng1_RPM") ipc.writeUW(0x66c0, RPM) ipc.sleep(100) end after, I tried, like yesterday with the IAS gauge. i checked the Lvar value: 3524953 LUA.1: L:AirspeedIndicatedNeedle=86.544639078253 Idem, for the airspeed, we have 14 figures, always positive. So, logically => 16bit, unisgned. So I tried with offset 66c8, while 1 do IAS = ipc.readLvar("L:AirspeedIndicatedNeedle") ipc.writeUW(0x66c8, IAS) ipc.sleep(100) end But it doesn't work... After, I tried with other offset (66C1, 66C2, 66FF,...) always same thing. But, to bsure that my script is good, I tried to delete the RPM script in offset 66c0, to put the airspeed in offset 66c0, and... that's work!! So my problem now is only from the offset. I'm not sure I understand everything about offset... Could you give me a little help? Thank a lot, best regard

Hi every body, I'm working to interface the A2A cessna to make a home cockpit. For the moment, I would like to see what can I do only with simple arduino and mobiflight. And I have already my first results! 😃 I have interfaced some switches, like battery, alternateur, ... with simple Lua script. For example, this is my script wich I can drive the battery switch: battery = ipc.readUB(0x3340) if battery > 0 then ipc.writeLvar("L:Battery1Switch",1) else ipc.writeLvar("L:Battery1Switch",0) end It works greatly! Today, I succeeded to drive my first gauge!! 😅 For the RPM, with motor stepper, with Lvar and Lua script! and this script... while 1 do Eng1_RPM = ipc.readLvar("L:Eng1_RPM") ipc.writeSW(0x66c8, Eng1_RPM) ipc.sleep(100) end So, after that, I thought that it would be simple to drive other gauge, on other free offset. But no result for the moment... I try to drive the IAS gauge, with this script, but it doesn't work... I've tried on many different offset... while 1 do IAS = ipc.readLvar("L:AirspeedIndicatedNeedle") ipc.writeSD(0x9200, IAS) ipc.sleep(100) end Could someone have an idea? Best regard
