end

#get_chip_temperature ⇒ Object

Returns the temperature as measured inside the microcontroller. The value returned is not the ambient temperature!

The temperature is only proportional to the real temperature and it has bad accuracy. Practically it is only useful as an indicator for temperature changes.

end

#get_identity ⇒ Object

Returns the UID, the UID where the Bricklet is connected to, the position, the hardware and firmware version as well as the device identifier.

The position can be ‘a’, ‘b’, ‘c’, ‘d’, ‘e’, ‘f’, ‘g’ or ‘h’ (Bricklet Port). A Bricklet connected to an :ref:‘Isolator Bricklet <isolator_bricklet>` is always at position ’z’.

The device identifier numbers can be found :ref:‘here <device_identifier>`. |device_identifier_constant|

end

#get_resistance ⇒ Object

Returns the value as measured by the MAX31865 precision delta-sigma ADC.

The value can be converted with the following formulas:

  • Pt100: resistance = (value * 390) / 32768

  • Pt1000: resistance = (value * 3900) / 32768

If you want to get the value periodically, it is recommended to use the CALLBACK_RESISTANCE callback. You can set the callback configuration with BrickletIndustrialPTC#set_resistance_callback_configuration.

#get_spitfp_error_count ⇒ Object

Returns the error count for the communication between Brick and Bricklet.

The errors are divided into

  • ACK checksum errors,

  • message checksum errors,

  • framing errors and

  • overflow errors.

The errors counts are for errors that occur on the Bricklet side. All Bricks have a similar function that returns the errors on the Brick side.

end

#is_sensor_connected ⇒ Object

Returns true if the sensor is connected correctly.

If this function returns false, there is either no Pt100 or Pt1000 sensor connected, the sensor is connected incorrectly or the sensor itself is faulty.

If you want to get the status automatically, it is recommended to use the CALLBACK_SENSOR_CONNECTED callback. You can set the callback configuration with BrickletIndustrialPTC#set_sensor_connected_callback_configuration.

end

#reset ⇒ Object

Calling this function will reset the Bricklet. All configurations will be lost.

After a reset you have to create new device objects, calling functions on the existing ones will result in undefined behavior!

#set_bootloader_mode(mode) ⇒ Object

Sets the bootloader mode and returns the status after the requested mode change was instigated.

You can change from bootloader mode to firmware mode and vice versa. A change from bootloader mode to firmware mode will only take place if the entry function, device identifier and CRC are present and correct.

This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.

end

#set_moving_average_configuration(moving_average_length_resistance, moving_average_length_temperature) ⇒ Object

Sets the length of a ‘moving averaging <en.wikipedia.org/wiki/Moving_average>`__ for the resistance and temperature.

Setting the length to 1 will turn the averaging off. With less averaging, there is more noise on the data.

New data is gathered every 20ms. With a moving average of length 1000 the resulting averaging window has a length of 20s. If you want to do long term measurements the longest moving average will give the cleanest results.

The default values match the non-changeable averaging settings of the old PTC Bricklet 1.0

end

#set_noise_rejection_filter(filter) ⇒ Object

Sets the noise rejection filter to either 50Hz (0) or 60Hz (1). Noise from 50Hz or 60Hz power sources (including harmonics of the AC power’s fundamental frequency) is attenuated by 82dB.

end

#set_resistance_callback_configuration(period, value_has_to_change, option, min, max) ⇒ Object

The period is the period with which the CALLBACK_RESISTANCE callback is triggered periodically. A value of 0 turns the callback off.

If the ‘value has to change`-parameter is set to true, the callback is only triggered after the value has changed. If the value didn’t change within the period, the callback is triggered immediately on change.

If it is set to false, the callback is continuously triggered with the period, independent of the value.

It is furthermore possible to constrain the callback with thresholds.

The ‘option`-parameter together with min/max sets a threshold for the CALLBACK_RESISTANCE callback.

The following options are possible:

"Option", "Description"

"'x'",    "Threshold is turned off"
"'o'",    "Threshold is triggered when the value is *outside* the min and max values"
"'i'",    "Threshold is triggered when the value is *inside* or equal to the min and max values"
"'<'",    "Threshold is triggered when the value is smaller than the min value (max is ignored)"
"'>'",    "Threshold is triggered when the value is greater than the min value (max is ignored)"

If the option is set to ‘x’ (threshold turned off) the callback is triggered with the fixed period.

end

#set_status_led_config(config) ⇒ Object

Sets the status LED configuration. By default the LED shows communication traffic between Brick and Bricklet, it flickers once for every 10 received data packets.

You can also turn the LED permanently on/off or show a heartbeat.

If the Bricklet is in bootloader mode, the LED is will show heartbeat by default.

#set_temperature_callback_configuration(period, value_has_to_change, option, min, max) ⇒ Object

The period is the period with which the CALLBACK_TEMPERATURE callback is triggered periodically. A value of 0 turns the callback off.

If the ‘value has to change`-parameter is set to true, the callback is only triggered after the value has changed. If the value didn’t change within the period, the callback is triggered immediately on change.

If it is set to false, the callback is continuously triggered with the period, independent of the value.

It is furthermore possible to constrain the callback with thresholds.

The ‘option`-parameter together with min/max sets a threshold for the CALLBACK_TEMPERATURE callback.

#set_wire_mode(mode) ⇒ Object

#set_write_firmware_pointer(pointer) ⇒ Object

Sets the firmware pointer for BrickletIndustrialPTC#write_firmware. The pointer has to be increased by chunks of size 64. The data is written to flash every 4 chunks (which equals to one page of size 256).

This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.

#write_firmware(data) ⇒ Object
