Thanks for that, The displaying of it works if I use the p3d radio dials. It's using my arduino radio dials, I can't seem to send a correct value back.

Social commentary again :) Ok, so I have changed it a little, as I was still missing jumps, and now have reading the values working 100% up to FL400. Problem is in the sending back.. ipc.control(65892,1) should be the code to send to increase the ap altitude correct? I've tried offset writes, but gremlins start to appear after a bit of use. I would rather send offsets, but yeah.... I'm not having much joy.

Ok, found it out, and boy do I feel stupid... Sending offset/65536... In the arduino receive the number x x/3*100 does the trick!!!!

Thanks for that, yes it worked :) But it's not accurate - I think because I was trying to truncate it too much (4 characters). But everynow and again it keeps missing a number. So it may display 1900 in the sim, but shows 2000 on the display - and then 2000 on the sim, and still 2000 on the display. I've tried all sorts of conversions... So I've changed the script so it sends offset value/65536 What manipulation can I perform on this to get accurate readings on the lcd and the plane. Or am I at a point where I need to put in an array and all the inaccurate numbers write a correct one) I'm using the feet value of 3.28083989501312

Ok, Thanks to Paul, I managed to get my radios working. I've managed to get heading, obs, and ias working for an AP. But having issues with altitude. send_padded("altitude", alt/100,4); // alt was 600 so sends 6 to the function void send_padded ( char* name, int value, int padded) { char buffer [20]; switch (padded){ case 4: sprintf (buffer, "%s:%04d\n", name, value); break; } // lcd2.setCursor(0,3); // lcd2.print("S:"); // lcd2.print(buffer); Serial.write (buffer); } So this would send altitude:0006 to lua if string.match(str, "altitude:(%d)") then state = tonumber(string.match(str, "altitude:(%d)")) current = ((state*65536)*foot/100) ipc.writeUD(0x07d4, current ) end But this isn't setting the correct value, as the plane still shows 00000 If I update the plane it comes up 100 short in my code as well... value = (value/65536)* foot/100 is the code I use to send to the arduino. Literally pulling my hair out, and freaking out about the codes for the vertical speed as well. These are the last two areas that I have left to complete my radio/ap panel.

So I've got an Arduino running radios etc, but I can't get it to swap the frequencies. I send the code from my arduino "swapc1" Lua accepts this, but I can't get the following to work. Sent from Arduino: swapc1:1 char buffer [20]; sprintf (buffer, "%s:%d\n", name, value); // lcd2.setCursor(0,3); // lcd2.print("S:"); // lcd2.print(buffer); Serial.write (buffer); Lua Script if string.match (str,"swapc1:(%x)") then ipc.control(66444,1) end I did have a script trying to manually swap them as well, but would rather use the presets. Anyone able to assist?
