B4R Question InLine C and Dallas-Address

[newbie]

Hi,

can someone tell me
how to transfer the dallas-device-address from inline-c
to a string-array defined in B4R ??????
I have try a lot but nothing work :-(


Thanks for any help

Not so simple and the exact details depend on the way the array is created and who is expected to release it.

There are several libraries and related threads: https://www.b4x.com/android/forum/pages/results/?query=b4r+dallas

If they don't help then post the not working inline C code.

Hi,

here is a part of the code,
in void getaddress i want to store the requested addresses in the main string-array
all what i have try give me a conversion error.
All other void works fine.

Private SolarAddress(10) As string  ' here i want to store the requested addresses


Sub Init
    Log("Init Dallas")
    RunNative("setup", Null)
End Sub


Sub GetAllTemp
    Log("Get Dallas Temp --------")
    
    RunNative("getcount", Null)
    RunNative("getaddress", Null)
    
    Log("Solar  SensorCount1: ",SensorCount1)
    For i= 0 To 9
        Log("      ",i,": ",SolarAddress(i))
    Next
    
    
    Log("Kamin  SensorCount2: ",SensorCount2)
    Log("Puffer SensorCount3: ",SensorCount3)
    Log("Haus   SensorCount4: ",SensorCount4)
    
    RunNative("gettemp", Null)
    
    Log("Kessel   : ",tKessel)
    Main.mData(4).Value = tKessel
    
    Log("Kessel R1: ",tKesselR1)
    Main.mData(5).Value = tKesselR1
    
    Log("Kessel R2: ",tKesselR2)
    Main.mData(6).Value = tKesselR2
    
    Log("Kessel R3: ",tKesselR3)
    Main.mData(30).Value = tKesselR3

This code cannot work.
Don't try to convert anything to string. Strings are bad.

In this case the best solution is to create a native method that returns an int with the address.
