class PiXtendV2L(pixtendv2core.PiXtendV2Core) |
| |
The PiXtendV2L class is based off of the PiXtendV2Core class, which provides basic and most common functions for
PiXtend V2. This class must implement the abstract methods _unpack_spi_data and _pack_spi_data otherwise there
can be no functioning data communication and no usable object at runtime.
Notice:
Only ONE single instance of this class is allowed per Raspberry Pi. Do not create multiple objects in the
same or a different program. This will lead to inconsistent states of the PiXtend board used. The PPLv2 and the
SPI Bus of the Raspberry Pi cannot handle multiple instances or objects.

- Method resolution order:
- PiXtendV2L
- pixtendv2core.PiXtendV2Core
- __builtin__.object
Methods defined here:
- __init__(self, spi_speed=700000, com_interval=0.03, model=76, disable_dac=False)
- Constructor of the PixtendV2L class. Create needed variables to store the settings and values for the PiXtend V2
board which are transferred via SPI to the on-board microcontroller. The the core class (PiXtendV2Core) does
not provide all needed variables and functions, only the basic and most common functions of the PiXtend V2
system. This class has to build and supply the rest.
:param int spi_speed: SPI communication speed, default is 700000
:param float com_interval: Cycle time of the communication, how often is data exchanged between the
Raspberry Pi and the microcontroller on the PiXtend board, default is 30 ms
:param int model: The model number of the PiXtend board which is used. S = 83 and L = 76
:param bool disable_dac: The DAC (analog output) can be disabled to allow the use of the CAN-Bus on the
PiXtend V2 -L- board
- close(self)
- The 'close' function needs to be called to terminate the asynchronous SPI communication in the background and to
close the SPI driver. This function must be called before the PiXtendV2L object is destroyed in the program
it is used in.

:rtype: float
- temp3
- Get the converted temperature value from temperature input 3 from a DHT11 or DHT22 sensor.
:return: Current value
:rtype: float
- temp_input0_raw
- Get the temperature raw value from temperature input 0.
:return: Current value
:rtype: int
- temp_input1_raw
- Get the temperature raw value from temperature input 1.
:return: Current value
:rtype: int
- temp_input2_raw
- Get the temperature raw value from temperature input 2.
:return: Current value
:rtype: int
- temp_input3_raw
- Get the temperature raw value from temperature input 3.
:return: Current value
:rtype: int
- uc_state
- The UCState byte from the microcontroller contains information of the following internal states:
Bit 0: Run - The microcontroller is up and running, this is just a helper bit
Bit 4: Error0 - Bit 0 of the 4 bit error number from the microcontroller. Together with the next 3
Bit 5: Error1 - bits a 4 bit number can be formed which results in an error number which is
Bit 6: Error2 - listed in the SPI protocol specification or the software manual.
Bit 7: Error3
:return: Current value
:rtype: int
- uc_warnings
- The UCWarnings byte from the microcontroller contains information of the following internal errors:
Bit 1: RetainCRCError - Signals a CRC error in the retain data in the microcontroller
Bit 2: RetainVoltageError - The supply voltage is below 19 volts, the Retain memory option cannot be used.
:return: Current value
:rtype: int
- use_fahrenheit
- Get or Set if the conversion of the temperature raw value should be done in Fahrenheit.
Default is 'False', meaning by getting the temperature from temp0 to temp3
the value will be in degrees Celsius, if set to 'True' the values will be in Fahrenheit.
:returns: Bool value, 'False' for Celsius and 'True' for Fahrenheit
:rtype: bool
- watchdog
- Get or Set the PiXtend V2 watchdog option. WDT_OFF or 0 ms means the watchdog is disabled. One of the
following time values 16 ms, 32 ms, 64 ms, 125 ms, 250 ms, 500 ms, 1000 ms (1s), 2000 ms (2s), 4000 ms (4s)
and 8000 ms (8s) turns the watchdog function in the microcontroller on. If no SPI communication occurs within
this time frame, the microcontroller will stop working and goes into save state. Only a reset or power cycle
will bring it back to life once it has entered this stage.
:return: Current value
:rtype: int
:raises ValueError: If the passed value is not one of the following: 16, 32, 64, 125, 250, 500, 1000,
2000, 4000 or 8000

- __metaclass__ = <class 'abc.ABCMeta'>
- Metaclass for defining Abstract Base Classes (ABCs).
Use this metaclass to create an ABC. An ABC can be subclassed
directly, and then acts as a mix-in class. You can also register
unrelated concrete classes (even built-in classes) and unrelated
ABCs as 'virtual subclasses' -- these and their descendants will
be considered subclasses of the registering ABC by the built-in
issubclass() function, but the registering ABC won't show up in
their MRO (Method Resolution Order) nor will method
implementations defined by the registering ABC be callable (not
even via super()).
