Command Structure¶

The common options of the call and dispatch commands are documented here. The specific command structure is shown below.

tinkerforge call industrial-dual-analog-in-v2-bricklet [<option>..] <uid> <function> [<argument>..]¶

Parameters:	<uid> – Type: String <function> – Type: String

The call command is used to call a function of the Industrial Dual Analog In Bricklet 2.0. It can take several options:

• --help shows help for the specific call command and exits
• --list-functions shows a list of known functions of the Industrial Dual Analog In Bricklet 2.0 and exits

tinkerforge dispatch industrial-dual-analog-in-v2-bricklet [<option>..] <uid> <callback>¶

Parameters:	<uid> – Type: String <callback> – Type: String

The dispatch command is used to dispatch a callback of the Industrial Dual Analog In Bricklet 2.0. It can take several options:

• --help shows help for the specific dispatch command and exits
• --list-callbacks shows a list of known callbacks of the Industrial Dual Analog In Bricklet 2.0 and exits

tinkerforge call industrial-dual-analog-in-v2-bricklet <uid> <function> [<option>..] [<argument>..]¶

Parameters:	<uid> – Type: String <function> – Type: String

The <function> to be called can take different options depending of its kind. All functions can take the following options:

• --help shows help for the specific function and exits

Getter functions can take the following options:

• --execute <command> shell command line to execute for each incoming response (see section about output formatting for details)

Setter functions can take the following options:

• --expect-response requests response and waits for it

The --expect-response option for setter functions allows to detect timeouts and other error conditions calls of setters as well. The device will then send a response for this purpose. If this option is not given for a setter function then no response is sent and errors are silently ignored, because they cannot be detected.

Basic Functions¶

tinkerforge call industrial-dual-analog-in-v2-bricklet <uid> get-voltage <channel>¶

Parameters:	<channel> – Type: Int, Range: [0 to 1]
Output:	voltage – Type: Int, Unit: 1 mV, Range: [-35000 to 35000]

Returns the voltage for the given channel.

If you want to get the value periodically, it is recommended to use the voltage callback. You can set the callback configuration with set-voltage-callback-configuration.

tinkerforge call industrial-dual-analog-in-v2-bricklet <uid> set-channel-led-config <channel> <config>¶

Parameters:	<channel> – Type: Int, Range: [0 to 1] <config> – Type: Int, Range: See symbols, Default: 3
Output:	no output

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 set-channel-led-status-config.

By default all channel LEDs are configured as "Channel Status".

The following symbols are available for this function:

For <config>:

• channel-led-config-off = 0
• channel-led-config-on = 1
• channel-led-config-show-heartbeat = 2
• channel-led-config-show-channel-status = 3

tinkerforge call industrial-dual-analog-in-v2-bricklet <uid> get-channel-led-config <channel>¶

Parameters:	<channel> – Type: Int, Range: [0 to 1]
Output:	config – Type: Int, Range: See symbols, Default: 3

Returns the channel LED configuration as set by set-channel-led-config

The following symbols are available for this function:

For config:

• channel-led-config-off = 0
• channel-led-config-on = 1
• channel-led-config-show-heartbeat = 2
• channel-led-config-show-channel-status = 3

tinkerforge call industrial-dual-analog-in-v2-bricklet <uid> set-channel-led-status-config <channel> <min> <max> <config>¶

Parameters:	<channel> – Type: Int, Range: [0 to 1] <min> – Type: Int, Unit: 1 mV, Range: [-231 to 231 - 1], Default: 0 <max> – Type: Int, Unit: 1 mV, Range: [-231 to 231 - 1], Default: 10000 <config> – Type: Int, Range: See symbols, Default: 1
Output:	no output

Sets the channel LED status config. This config is used if the channel LED is configured as "Channel Status", see 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.

The following symbols are available for this function:

For <config>:

• channel-led-status-config-threshold = 0
• channel-led-status-config-intensity = 1

Callback Configuration Functions¶

tinkerforge call industrial-dual-analog-in-v2-bricklet <uid> set-voltage-callback-configuration <channel> <period> <value-has-to-change> <option> <min> <max>¶

Parameters:	<channel> – Type: Int, Range: [0 to 1] <period> – Type: Int, Unit: 1 ms, Range: [0 to 232 - 1], Default: 0 <value-has-to-change> – Type: Bool, Default: false <option> – Type: Char, Range: See symbols, Default: x <min> – Type: Int, Unit: 1 mV, Range: [-231 to 231 - 1], Default: 0 <max> – Type: Int, Unit: 1 mV, Range: [-231 to 231 - 1], Default: 0
Output:	no output

The period is the period with which the 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 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.

The following symbols are available for this function:

For <option>:

• threshold-option-off = x
• threshold-option-outside = o
• threshold-option-inside = i
• threshold-option-smaller = <
• threshold-option-greater = >

tinkerforge call industrial-dual-analog-in-v2-bricklet <uid> get-voltage-callback-configuration <channel>¶

Parameters:	<channel> – Type: Int, Range: [0 to 1]
Output:	period – Type: Int, Unit: 1 ms, Range: [0 to 232 - 1], Default: 0 value-has-to-change – Type: Bool, Default: false option – Type: Char, Range: See symbols, Default: x min – Type: Int, Unit: 1 mV, Range: [-231 to 231 - 1], Default: 0 max – Type: Int, Unit: 1 mV, Range: [-231 to 231 - 1], Default: 0

Returns the callback configuration as set by set-voltage-callback-configuration.

The following symbols are available for this function:

For option:

• threshold-option-off = x
• threshold-option-outside = o
• threshold-option-inside = i
• threshold-option-smaller = <
• threshold-option-greater = >

tinkerforge call industrial-dual-analog-in-v2-bricklet <uid> set-all-voltages-callback-configuration <period> <value-has-to-change>¶

Parameters:	<period> – Type: Int, Unit: 1 ms, Range: [0 to 232 - 1], Default: 0 <value-has-to-change> – Type: Bool, Default: false
Output:	no output

The period is the period with which the 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.

New in version 2.0.6 (Plugin).

tinkerforge call industrial-dual-analog-in-v2-bricklet <uid> get-all-voltages-callback-configuration¶

This callback is triggered periodically according to the configuration set by set-all-voltages-callback-configuration.

The parameters are the same as get-all-voltages.

New in version 2.0.6 (Plugin).

Internal Functions¶

Internal functions are used for maintenance tasks such as flashing a new firmware of changing the UID of a Bricklet. These task should be performed using Brick Viewer instead of using the internal functions directly.

tinkerforge call industrial-dual-analog-in-v2-bricklet <uid> set-bootloader-mode <mode>¶

Parameters:	<mode> – Type: Int, Range: See symbols
Output:	status – Type: Int, Range: See symbols

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.

The following symbols are available for this function:

For <mode>:

• bootloader-mode-bootloader = 0
• bootloader-mode-firmware = 1
• bootloader-mode-bootloader-wait-for-reboot = 2
• bootloader-mode-firmware-wait-for-reboot = 3
• bootloader-mode-firmware-wait-for-erase-and-reboot = 4

For status:

• bootloader-status-ok = 0
• bootloader-status-invalid-mode = 1
• bootloader-status-no-change = 2
• bootloader-status-entry-function-not-present = 3
• bootloader-status-device-identifier-incorrect = 4
• bootloader-status-crc-mismatch = 5

tinkerforge call industrial-dual-analog-in-v2-bricklet <uid> get-bootloader-mode¶

Output:	mode – Type: Int, Range: See symbols

Returns the current bootloader mode, see set-bootloader-mode.

The following symbols are available for this function:

For mode:

• bootloader-mode-bootloader = 0
• bootloader-mode-firmware = 1
• bootloader-mode-bootloader-wait-for-reboot = 2
• bootloader-mode-firmware-wait-for-reboot = 3
• bootloader-mode-firmware-wait-for-erase-and-reboot = 4

Parameters:	<pointer> – Type: Int, Unit: 1 B, Range: [0 to 232 - 1]
Output:	no output

Sets the firmware pointer for 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.

tinkerforge call industrial-dual-analog-in-v2-bricklet <uid> write-firmware <data>¶

Parameters:	<data> – Type: Int Array, Length: 64, Range: [0 to 255]
Output:	status – Type: Int, Range: [0 to 255]

Writes 64 Bytes of firmware at the position as written by set-write-firmware-pointer before. The firmware is written to flash every 4 chunks.

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.

tinkerforge call industrial-dual-analog-in-v2-bricklet <uid> write-uid <uid>¶

Parameters:	<uid> – Type: Int, Range: [0 to 232 - 1]
Output:	no output

Writes a new UID into flash. If you want to set a new UID you have to decode the Base58 encoded UID string into an integer first.

We recommend that you use Brick Viewer to change the UID.

tinkerforge call industrial-dual-analog-in-v2-bricklet <uid> read-uid¶

Output:	uid – Type: Int, Range: [0 to 232 - 1]

Returns the current UID as an integer. Encode as Base58 to get the usual string version.
