#set_all_voltages_callback_configuration(period, value_has_to_change) ⇒ Object

The period is the period with which the CALLBACK_ALL_VOLTAGES 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 at least one of the values has changed. If the values 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.

end

#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.

#set_calibration(offset, gain) ⇒ Object

Sets offset and gain of MCP3911 internal calibration registers.

See MCP3911 datasheet 7.7 and 7.8. The Industrial Dual Analog In Bricklet 2.0 is already factory calibrated by Tinkerforge. It should not be necessary for you to use this function

end

#set_channel_led_config(channel, config) ⇒ Object

Each channel has a corresponding LED. You can turn the LED off, on or show a heartbeat. You can also set the LED to “Channel Status”. In this mode the LED can either be turned on with a pre-defined threshold or the intensity of the LED can change with the measured value.

You can configure the channel status behavior with BrickletIndustrialDualAnalogInV2#set_channel_led_status_config.

By default all channel LEDs are configured as “Channel Status”.

end

#set_channel_led_status_config(channel, min, max, config) ⇒ Object

Sets the channel LED status config. This config is used if the channel LED is configured as “Channel Status”, see BrickletIndustrialDualAnalogInV2#set_channel_led_config.

For each channel you can choose between threshold and intensity mode.

In threshold mode you can define a positive or a negative threshold. For a positive threshold set the “min” parameter to the threshold value in mV above which the LED should turn on and set the “max” parameter to 0. Example: If you set a positive threshold of 10V, the LED will turn on as soon as the voltage exceeds 10V and turn off again if it goes below 10V. For a negative threshold set the “max” parameter to the threshold value in mV below which the LED should turn on and set the “min” parameter to 0. Example: If you set a negative threshold of 10V, the LED will turn on as soon as the voltage goes below 10V and the LED will turn off when the voltage exceeds 10V.

In intensity mode you can define a range in mV that is used to scale the brightness of the LED. Example with min=4V, max=20V: The LED is off at 4V, on at 20V and the brightness is linearly scaled between the values 4V and 20V. If the min value is greater than the max value, the LED brightness is scaled the other way around.

#set_sample_rate(rate) ⇒ Object

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.

end

#set_voltage_callback_configuration(channel, period, value_has_to_change, option, min, max) ⇒ Object

The period is the period with which the CALLBACK_VOLTAGE 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_VOLTAGE 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.

#set_write_firmware_pointer(pointer) ⇒ Object

Sets the firmware pointer for BrickletIndustrialDualAnalogInV2#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.

You can only write firmware in bootloader mode.

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