+### 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 Codes
+
+| Descriptive Name            | Value    | Meaning                                                  |
+|:----------------------------|---------:|:---------------------------------------------------------|
+| `ERROR_NONE`                | 0b00000000 | No error. The device is functioning properly, there are no errors present. |
+| `ERROR_MAX_CURRENT_EXCEEDED`| 0b00000001 | The maximum current consumption has been exceeded. There might be an overload condition on the device. |
+| `ERROR_CURRENT_BELOW_MIN`   | 0b00000010 | The current consumption is below the permissible minimum. There may be an issue with the power supply. |
+| `ERROR_MAX_TEMP_EXCEEDED`   | 0b00000100 | The maximum temperature has been exceeded. The device could overheat. |
+| `ERROR_TEMP_BELOW_MIN`      | 0b00001000 | The temperature is below the permissible minimum. There is a risk of hypothermia or other temperature-related issues. |
+| `ERROR_MAX_HUMI_EXCEEDED`   | 0b00010000 | The maximum humidity has been exceeded. This could lead to moisture-related problems. |
+| `ERROR_HUMI_BELOW_MIN`      | 0b00100000 | 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.
