class Flags(_ctypes.Union) |
| |
A class using the ctypes Union to combine the 8 bits from the FlagsBits class (field) and one byte (type c_uint8)
into one memory space overlaying each other. This way each single bit within a byte can be accessed directly by
its individual name. Using the asBytes field element allows to set all 8 bits at once.

class Pixtend(__builtin__.object) |
| |
The PiXtend class derived from Python object can be used to control and manipulate states of inputs and outputs
(analog and digital) in the microcontroller on the PiXtend board via the Raspberry Pi's SPI bus.
Import the pixtend file: from pixtendlib import Pixtend
Creating an instance: p = Pixtend()
Activate the SPI bus: p.open()
Read relay 0 state: mystate = p.relay0
Set relay 1 to on: p.relay1 = p.ON
|
| |
Methods defined here:
- __del__(self)
- Destructor of the Pixtend class.
Delete all objects, clean up GPIOs and close the SPI bus when the Pixtend instance is destroyed.
- __init__(self)
- Constructor of the Pixtend class.
Create all objects and variables needed, set defaults for the RPi SPI bus, the GPIOs and activate
the BCM GPIO layout on the Raspberry Pi. The GPIO 24 needs to be an output and set to 'on' to enable
the communication with the microcontroller on the PiXtend board via SPI Master 0 and Chip Select 0.
- auto_mode(self)
- Method for the auto(matic) mode data transfer. The settings and values of all applicable
properties like outputs, GPIO and PWM configuration for the PiXtend board are sent to the microcontroller
in one block and states and values of all digital and analog inputs and outputs are received as response.
This is the most efficient way to work with the microcontroller on the PiXtend board.
In the beginning the auto_mode method should be called until the return value is 0 and the microcontroller's
uc_state is 1, meaning the communication is working and the microcontroller has entered the 'Run' state.
After that the auto_mode method does not need to be called on a regular basis, but when new values are needed
or outputs have to be turned on or off.
Example:
if p.auto_mode() == 0 and p.uc_status == 1:
p.relay0 = p.ON
:return: 0 means communication is ok and running, -1 means crc error and/or a problem with the received data

on the PiXtend board.

with the DAC on the PiXtend board.
:param int spi_channel: Number of the SPI master, default is 0, optional parameter
:param int spi_cs: Chip Select (CS) for the SPI master for the DAC, default is 1, optional parameter
:param int spi_speed: SPI frequency, default 100 kHz, optional parameter

- pwm_ctrl_configure(self)
- Configures the PWM control of the microcontroller on the PiXtend board. The data transferred includes
all PWM settings like the Mode, OD setting and the Clock Select for the PWMs as well as the frequency.
- set_dac_output(self, value)
- Set the analog output value for the chosen DAC. The active DAC can be chosen with the property 'dac_selection'.
The value 0 or constant DAC_A selects DAC A and the value 1 or constant DAC_B selects DAC B.
Example:
Selecting and setting DAC A:
p.dac_selection = p.DAC_A
p.set_dac_output (512)
Selecting and setting DAC B:
p.dac_selection = p.DAC_B
p.set_dac_output (256)
:param int value: Output value for the chosen DAC.
:raises ValueError: If value is smaller then 0 or larger then 1023

- t2_dht22
- Get the converted temperature value from temperature input 2 from a DHT22 sensor.
- t3_dht11
- Get the converted temperature value from temperature input 3 from a DHT11 sensor.
- t3_dht22
- Get the converted temperature value from temperature input 3 from a DHT22 sensor.
- temp_input0_raw
- Get the temperature raw value from temperature input 0.
- temp_input1_raw
- Get the temperature raw value from temperature input 1.
- temp_input2_raw
- Get the temperature raw value from temperature input 2.
- temp_input3_raw
- Get the temperature raw value from temperature input 3.
- uc_board_version
- Get the PiXtend board version.
Example:
A value of 13 means board version 1.3.x
:return: Board version of the PiXtend board
:rtype: c_uint8
- uc_control
- Get or Set the microcontroller's control register. If the automatic mode is off, setting
a new value will have immediate effect.
:return: Current value of the control byte in the microcontroller
:rtype: c_uint8
:raises ValueError: If the passed value is smaller then 0 or larger then 255
- uc_fw_version
- Get the microcontroller firmware version on the PiXtend board.
Example:
A value of 2 means firmware version 2.x is installed on the microcontroller
:return: Firmware version of the microcontroller on the PiXtend board
:rtype: c_uint8
- uc_status
- Get the microcontroller status byte.
:return: Status byte of the microcontroller on the PiXtend board
:rtype: c_uint8
- 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 t0_dht22 to t3_dht22 or from t0_dht11 to t3_dht11
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

class UcVersionBytes(_ctypes.Structure) |
| |
This is a structure for two (2) single bytes to store the firmware version and the board version reported by the
microcontroller on the PiXtend board.
Example:
UC_VERSIONH = 13 means board version is 1.3.x
UC_VERSIONL = 2 means firmware version 2.x is installed on the microcontroller
:type UC_VERSIONL : c_uint8
:type UC_VERSIONH : c_uint8
