Hallo,
ich bekomme folgende Fehlermeldung. Welhe ich zum ersten mal sehe.
Compiling C: fscontroll.c

fscontroll.c:685: confused by earlier errors, bailing out

Was bedeutet diese Fehlermeldung.
Dies entsteht durch folgedne Zeilen:1 | sensor->pressurereservend=sensor->mreserve*adc->float_ch[0]+sensor->breserve;
|
2 | sensor->pressurereservehpleft=MPRESERVELEFT*adc->float_ch[1]+BPRESERVELEFT;
|
3 | sensor->pressurereservehpright=MPRESERVERIGHT*adc->float_ch[2]+BPRESERVERIGHT;
|
4 | sensor->pressuresystem=sensor->msystem*adc->float_ch[3]+sensor->bsystem;
|
5 | sensor->pressureafterfilter=sensor->mfilter*adc->ch[4]+sensor->bfilter;
|
1 | Durch umsoriteren der Zeilen verschwindet der Fehler.
|
2 | sensor->pressureafterfilter=sensor->mfilter*adc->ch[4]+sensor->bfilter;
|
3 | sensor->pressurereservend=sensor->mreserve*adc->float_ch[0]+sensor->breserve;
|
4 | sensor->pressurereservehpleft=MPRESERVELEFT*adc->float_ch[1]+BPRESERVELEFT;

5 | sensor->pressurereservehpright=MPRESERVERIGHT*adc->float_ch[2]+BPRESERVERIGHT;
