|
||||
|
||||
### Error codes in `errorCode`
|
||||
|
||||
The variable `globalError` is used as a bitmask, where each bit represents a specific error condition. Here are the possible error codes and their meanings:
|
||||
|
||||
#### `ERROR_NONE` (0b0000000000000000)
|
||||
|
||||
No error. The device is functioning properly, there are no errors present.
|
||||
|
||||
#### `ERROR_MAX_CURRENT_EXCEEDED` (0b0000000000000001)
|
||||
|
||||
The maximum current consumption has been exceeded. There might be an overload condition on the device.
|
||||
|
||||
#### `ERROR_CURRENT_BELOW_MIN` (0b0000000000000010)
|
||||
|
||||
The current consumption is below the permissible minimum. There may be an issue with the power supply.
|
||||
|
||||
#### `ERROR_MAX_TEMP_EXCEEDED` (0b0000000000000100)
|
||||
|
||||
The maximum temperature has been exceeded. The device could overheat.
|
||||
|
||||
#### `ERROR_TEMP_BELOW_MIN` (0b0000000000001000)
|
||||
|
||||
The temperature is below the permissible minimum. There is a risk of hypothermia or other temperature-related issues.
|
||||
|
||||
#### `ERROR_MAX_HUMI_EXCEEDED` (0b0000000000010000)
|
||||
|
||||
The maximum humidity has been exceeded. This could lead to moisture-related problems.
|
||||
|
||||
#### `ERROR_HUMI_BELOW_MIN` (0b0000000000100000)
|
||||
|
||||
The humidity is below the permissible minimum. There is a risk of low humidity.
|
||||
|
||||
Please note that multiple errors can occur simultaneously as the bitmasks can be combined. For example, `ERROR_MAX_TEMP_EXCEEDED | ERROR_MAX_HUMI_EXCEEDED` could indicate that both the maximum temperature and humidity have been exceeded.
|
||||
|
||||
## Functions
|
||||
|
||||
### configureIna226()
|
||||
|
||||
The `configureIna226()` function configures the INA226 sensor with specific settings.
|
||||
|
||||
#### Steps:
|
||||
1. **Set Minimal Shunt:**
|
||||
- Description: Overwrites the INA226_ERR_SHUNT_LOW parameter with a minimal shunt value.
|
||||
The ina226 library default values is 0.001.
|
||||
- Code: `ina226.setMinimalShunt(0.0001);`
|
||||
|
||||
2. **Set Maximum Current Shunt:**
|
||||
- Description: Sets the maximum current shunt value with normalization (3rd parameter set to true) to 3 floating-point accuracy.
|
||||
- Code:
|
||||
```cpp
|
||||
ina226Status = ina226.setMaxCurrentShunt(current ampere,
|
||||
shunt ohm, true);
|
||||
```
|
||||
|
||||
- **Demo Mode 1 Path ("/demo1")**
|
||||
- HTTP-Methode: GET
|
||||
- Startet den Demo-Modus 1: Demonstriert einen lade-/entladezyklus ab der Hälfte der maximalen Kapazität mit variablem Strom bei 25,6A.
|
||||
3. **Set Averaging:**
|
||||
- Description: Sets the averaging mode to use 16 samples for building an average value.
|
||||
- Code: `ina226.setAverage(2);`
|
||||
|
||||
- **Demo Mode 2 Path ("/demo2")**
|
||||
- HTTP-Methode: GET
|
||||
- Startet den Demo-Modus 2: Demonstriert einen ladezyklus ab 97% der maximalen Kapazität auf 100% mit 200A bei 25.6V.
|
||||
|
||||
- **Demo Mode 3 Path ("/demo3")**
|
||||
- HTTP-Methode: GET
|
||||
- Startet den Demo-Modus 3: Demonstriert einen entladezyklus ab 3% der maximalen Kapazität auf 0% mit -200A bei 25.6V.

Die HTML-Seiten werden dynamisch generiert und enthalten JavaScript für die Aktualisierung von Daten über AJAX-Anfragen. Die Konfigurationsseite ermöglicht es Benutzern, bestimmte Parameter über Schieberegler einzustellen und Änderungen zu speichern.
|
||||
|
||||
# Fehlermeldungen für den wert `errorCode`
|
||||
|
||||
Die Variable `globalError` wird als Bitmask verwendet, wobei jedes Bit eine bestimmte Fehlerbedingung repräsentiert. Hier sind die möglichen Fehlermeldungen und ihre Bedeutungen:
|
||||
|
||||
## `ERROR_NONE` (0b0000000000000000)
|
||||
|
||||
Kein Fehler. Das Gerät funktioniert ordnungsgemäß, es liegen keine Fehler vor.
|
||||
|
||||
## `ERROR_MAX_CURRENT_EXCEEDED` (0b0000000000000001)
|
||||
|
||||
Der maximale Stromverbrauch wurde überschritten. Möglicherweise liegt eine Überlastung des Geräts vor.
|
||||
|
||||
## `ERROR_CURRENT_BELOW_MIN` (0b0000000000000010)
|
||||
|
||||
Der aktuelle Stromverbrauch liegt unter dem zulässigen Minimum. Möglicherweise gibt es ein Problem mit der Stromzufuhr.
|
||||
|
||||
## `ERROR_MAX_TEMP_EXCEEDED` (0b0000000000000100)
|
||||
|
||||
Die maximale Temperatur wurde überschritten. Das Gerät könnte überhitzen.
|
||||
|
||||
## `ERROR_TEMP_BELOW_MIN` (0b0000000000001000)
|
||||
|
||||
Die Temperatur liegt unterhalb des zulässigen Minimums. Es besteht die Gefahr von Unterkühlung oder anderen temperaturbedingten Problemen.
|
||||
|
||||
## `ERROR_MAX_HUMI_EXCEEDED` (0b0000000000010000)
|
||||
|
||||
Die maximale Luftfeuchtigkeit wurde überschritten. Dies könnte zu feuchtigkeitsbedingten Problemen führen.
|
||||
|
||||
## `ERROR_HUMI_BELOW_MIN` (0b0000000000100000)
|
||||
|
||||
Die Luftfeuchtigkeit liegt unter dem zulässigen Minimum. Es besteht die Gefahr von zu geringer Luftfeuchtigkeit.
|
||||
|
||||
Bitte beachten Sie, dass mehrere Fehler gleichzeitig auftreten können, da die Bitmasken kombiniert werden können. Zum Beispiel könnte `ERROR_MAX_TEMP_EXCEEDED | ERROR_MAX_HUMI_EXCEEDED` darauf hinweisen, dass sowohl die maximale Temperatur als auch die maximale Luftfeuchtigkeit überschritten wurden.
