{ Get current temperature (unit is °C/100) }

            //t1_val := StringReplace (FloatToStrF(t1.GetTemperature/100 + t1_Korr, ffFixed, 8,2),'.',',',[rfReplaceAll]) ;

            //t2_val := StringReplace (FloatToStrF(t2.GetTemperature/100 + t2_Korr, ffFixed, 8,2),'.',',',[rfReplaceAll]) ;

            t3_val := StringReplace (FloatToStrF(t3.GetTemperature/100 + t3_Korr, ffFixed, 8,2),'.',',',[rfReplaceAll]) ;

            t4_val := StringReplace (FloatToStrF(t4.GetTemperature/100 + t4_Korr, ffFixed, 8,2),'.',',',[rfReplaceAll]) ;

            t5_val := StringReplace (FloatToStrF(t5.GetTemperature/100 + t5_Korr, ffFixed, 8,2),'.',',',[rfReplaceAll]) ;

            t6_val := StringReplace (FloatToStrF(t6.GetTemperature/100 + t6_Korr, ffFixed, 8,2),'.',',',[rfReplaceAll]) ;

 

            { get pressure & humidity }

            //h1_val := StringReplace (FloatToStrF(h1.GetHumidity/10  + h1_Korr, ffFixed, 8,2),'.',',',[rfReplaceAll]) ;

            //b1_val := StringReplace (FloatToStrF(b1.GetAirPressure/1000  + b1_Korr, ffFixed, 8,2),'.',',',[rfReplaceAll]) ;

 

If h1 or/and b1 will be (more than 4 brickletts) requested there is an exception:

 

External: SIGSEGV

...

    end;

    errorCode := GetErrorCodeFromData(result);

    if (errorCode = 0) then begin

...

 

This occures in all combinations.

So the h1_val throws an exception if you comment it in, but it doesnt if you comment out te tX_val lines? That doesn't make sense .

 

Can you make a minimal Program (including the initialization and so) that causes the exception?

Solved! Lazarus was confused. After restarting Lazarus and new compiler run all works fine.
