GFMcp lua issues

[Discoveroutdoors]

hi Pete and all how maybe able to help

 

i have found and modified Goflight pro MCP Lua script but I have hit wall with IAS/MACH Crossover. It is falling over in the IAS/MACH section stringSPD = string.format("%03d", SPD) saying unexpected symbol near '=='

 

is the a better why to write this section, if how can i fix it.

 

prevCRS1 = -1

prevSPD = -1

prevHDG = -1

prevalt = -1

prevVS = -1

prevCRS2 = -1

prevMACH = -1

--************************All Working*************************************************

while 1 do

CRS1 = ipc.readSW("0C4E")

if (CRS1 ~= prevCRS1) then

stringCRS1 = string.format("%03d", CRS1)

gfd.setDisplay(GFMCPPRO,0,0,stringCRS1)

prevCRS1 = CRS1

end

HDG = ipc.readSD("07CC")

if (HDG ~= prevHDG) then

stringHDG = string.format("%03d", ((HDG/65536)*360))

gfd.setDisplay(GFMCPPRO,0,2,stringHDG)

prevHDG = HDG

end

alt = ipc.readSD("07D4")

if (alt ~= prevalt) then

stringalt = string.format("%05d", ((alt/65536)*3.2809))

gfd.setDisplay(GFMCPPRO,0,3,stringalt)

prevalt = alt

end

VS = ipc.readSW("07F2")

if (VS ~= prevVS) then

stringalt = string.format("%05d", VS) 

gfd.setDisplay(GFMCPPRO,0,4,stringalt)

prevVS = VS

end

CRS2 = ipc.readSW("0C5E")

if (CRS2 ~= prevCRS2) then

stringCRS2 = string.format("%03d", CRS2)

gfd.setDisplay(GFMCPPRO,0,5,stringCRS2)

prevCRS2 = CRS2

end

--*******************************************************************************************************

 

--*******************IAS/MACH Crossover NEED Help!!!!!!!!!!!!!****************************************

if ipc.readUD("07DC" and "07E4") == 0 then

SPD = ipc.readSW("07E2")

end

It would have been more precise if you had shown me the actual error message. I had to extract your code, save it as a Lua, and try loading it to find the actual line. The error message is:

 

 *** LUA Error: E:\FSX\Modules\GFMCP.lua:50: unexpected symbol near '=='

 

In other words, Line 50, not the line 46 you quote! The line in question is therefore:

 

else ipc.readUD("07DC") == 1 and ("07E42") == 0 then

 

which has a meaningless statement between the else and the then, with several errors. Looks like you might have omitted an "if" and an "ipc.readUD" and inserted an extra character in "07E42" !!! And I think you've repeated this further down.

 

I do not provide a code debugging or checking service, sorry. Please use the tools available. Once you get the syntax correct throughout, use the FSUIPC built-in tracing facilty to find execution errors (see the Logging page).

thanks pete of look at the code, i did not then see that in line 50, I know you do not do code checking but i just need a freash eye.

 

thanks again
