Use LVAR from the SIM to initialize Local Variable - Hardware Programming

[CmteLucasGodoy]

Hello Everybody and Thank you in advance for helping me.
Im new in Programming so I'd like to ask you how I can use a LVAR from the SIM to initialize a local variable in my code?
I want to use the LVAR S_FCU_EFIS1_BARO_STD as initial situation for my local variable "situacaobaro".

function tunix()
end

fs2020_variable_subscribe("L:S_FCU_EFIS1_BARO_STD","INT",tunix)
fs2020_variable_write("L:S_FCU_EFIS1_BARO_STD","INT", 0)

function barostd_callback()

situationbaro = i want to read the value of this SIM LVAR >>>>>L:S_FCU_EFIS1_BARO_STD<<<<<<<<<

if situationbaro == 0 then
fs2020_variable_write("L:S_FCU_EFIS1_BARO_STD","INT", 1)
else
fs2020_variable_write("L:S_FCU_EFIS1_BARO_STD","INT", 0)
end
end

Thank you once again,
Lucas Godoy

Declare a local variable for the value you want. With the callback function called by the subscription, pass the value you're subscribed to, and assign it to the local var within that function.

Code: Select all

local myBaro

function tunix(val)
   mybaro = val
end
fs2020_variable_subscribe("L:S_FCU_EFIS1_BARO_STD","INT",tunix)

You can also do this for multiple vars with 1 function. Then those values will always be available in your script, and will get updated automatically to current value whenever they're changed in the sim.

Code: Select all

local myVar1
local myVar2
local myVar3

function setVars(val1, val2, val3)
   myVar1 = val1
   myVar2 = val2
   myVar3 = val3
end

fs2020_variable_subscribe("lvar1", "type", 
                                       "lvar2", "type", 
                                       "lvar3", "type", 
                                       setVars)
