DCS BIOS for the Gazelle

For more visibility, I open a new post concerning my questions about my library for the Gazelle.

 

My problem is related to the display of the AM radio.

The radio have 6 digits

Here is the argument

 

AM_Radio_freq_cent = 133,

AM_Radio_freq_dix = 134,

AM_Radio_freq_unite = 136,

AM_Radio_freq_dixieme = 138,

AM_Radio_freq_centieme = 139,

 

The frequency increases by 0.025

When i use this code

local function getVhfNavFreq()
local function a(n) return GetDevice(0):get_argument_value(n) end
return string.format("%.0f%.0f%.0f", a(133)*10, a(134)*10, a(136)*10) .. "." .. string.format("%.0f%.0f", a(138)*10, a(139)*10)
end
defineString("VHFNAV_FREQ", getVhfNavFreq, 7, "VHF NAV Radio", "VHF NAV Frequency")

 

I can see in the controle reference the frequency but the 2 last digit are wrong

 

0.000 = 0

0.025 = 3

0.050 = 5

0.075 = 8

 

I understand that i have to use this type of code

 

local vhf_lut1 = {
   ["0.00"] = "0",
["0.25"] = "3",
   ["0.50"] = "5",
   ["0.75"] = "8"
}

local function getVhfAmFreqency()
   local freq1 = string.format("%.0f",GetDevice(0):get_argument_value(133)):sub(3)
   local freq2 = string.format("%.0f", GetDevice(0):get_argument_value(134)):sub(3)
   local freq3 = string.format("%.0f", GetDevice(0):get_argument_value(136)):sub(3)
   local freq4 = string.format("%.0f", GetDevice(0):get_argument_value(138)):sub(3)
   local freq5 = vhf_lut1[string.format("%.2f",GetDevice(0):get_argument_value(139))]
return freq1 .. freq2 .. freq3 "." .. freq3 .. freq4 .. freq5
end

defineString("AM_DISPLAY", getVhfAmFreqency, 7, "VHFAM Panel", "VHFAM Display")

 

But it does not work and once again i dont understand :cry:

 

Thanks for your help

Always busy investigating

 

If I understand correctly, the %.0f is used to format the number exactly as many digits as needed by the argument??

 

Someone can explain to me wthat it is the function sub(3) ???

 

Thanks

:cheer3nc: EUREKA I found it

 

local vhf_lut1 = {
   ["0"] = "00",
["25"] = "25",
   ["50"] = "50",
   ["75"] = "75"
}

local function getVhfAmFreqency()
   local freq1 = string.format("%.0f", GetDevice(0):get_argument_value(133)*10)
   local freq2 = string.format("%.0f", GetDevice(0):get_argument_value(134)*10)--:sub(3)
   local freq3 = string.format("%.0f", GetDevice(0):get_argument_value(136)*10)--:sub(3)
   local freq4 = string.format("%.0f", GetDevice(0):get_argument_value(138)*10)--:sub(3)
   local freq5 = vhf_lut1[string.format("%.0f", GetDevice(0):get_argument_value(139)*100)]
return  freq1 .. freq2 .. freq3 .. "." .. freq4 .. freq5
end

defineString("AM_DISPLAY", getVhfAmFreqency, 7, "VHFAM Panel", "VHFAM Display")

 

But still want info about this :sub(3)

The Lua 5.1 Reference Manual has documentation on every language construct and standard library function, including string.format and string.sub.

 

some_string_variable:sub(n) simply returns everything from the third character onwards and is used to transform something like "0.25" to "25".

Thank you Ian for your explanations and your wonderful program :thumbup:
