SCD41 na SuplaDevice przez KPOP - jak wyciągac dane

[Marian1544]

@Malarz
Dzięki za wyjasnienie.

Odnośnie scd4x->getTemp(), chodziło mi o to że wszystkie trzy generują błędy odczytu w logach (SCD4x read error).

Odnośnie scd4x->getTemp(), chodziło mi o to że wszystkie trzy generują błędy odczytu w logach (SCD4x read error).

Wrzuć tu kawałek loga i cały kod, który go daje. Spróbuję to zdiagnozować.

Code: Select all

SCD4x Sensor detected.

więc:

Code: Select all

(scd.begin() == true)

Code: Select all

SCD4x read error

więc

Code: Select all

(scd.readMeasurement() == false)

Ja obstawiam problem w I2C, dodaj

Code: Select all

#include <Wire.h>

https://github.com/sparkfun/SparkFun_SC ... ibrary.cpp

[Marian1544]

@Bania
Nie, dodanie #include <Wire.h> nic nie zmienia.
Ale chyba niema co tego drążyć skoro scd4x->getChannel()->getValueDoubleFirst() działa bez błędów.

[malarz]

Crash wygląda jakby leciał przy rejestacji do serwera i jakby nie miał związku z tymi lcd.print.

Ja bym tego "if" w loop rozbił na framgenty i wstawił wszędzie logi debugowe. Dodatkowo najpierw pobierz do double odczyt, a w osobnej linii daj print (w logami pomiędzy).

Alternatywnie zdekoduj callstack - może będzie coś widać, choć na oko wygląda ubogo.

Błąd, o którym pisze @Marian1544 jest spowodowany najprawdopodobniej za częstym wywołaniem funkcji readValuesFromDevice().

Czy ta linia:
https://github.com/malarz-supla/supla-d ... CD4x.h#L44
powinna tam być, czy ta funkcja i tak jest wołana cyklicznie przez jakąś nadrzedną klasę?

Tak, ona tam powinna być, choć nie jest to zbyt eleganckie

[malarz]

Dzięki @klew.

@Marian1544 tym błędem w tych warunkach nie ma się po co przejmować. Ale lepiej zawsze czytać z "CalculatedValue" bo to jest wartość po dostrojeniu parametrami ustawianymi w cloud.

[Marian1544]

@malarz
Tak zrobię, dzięki.
