CALLBACK_INPUT_VALUE =

This callback is triggered periodically according to the configuration set by BrickletIO16V2#set_input_value_callback_configuration.

The parameters are the channel, a value-changed indicator and the actual value for the channel. The ‘changed` parameter is true if the value has changed since the last callback.

15
CALLBACK_ALL_INPUT_VALUE =

This callback is triggered periodically according to the configuration set by BrickletIO16V2#set_all_input_value_callback_configuration.

The parameters are the same as BrickletIO16V2#get_value. Additional the ‘changed` parameter is true if the value has changed since the last callback.

16
CALLBACK_MONOFLOP_DONE =

This callback is triggered whenever a monoflop timer reaches 0. The parameters contain the channel and the current value of the channel (the value after the monoflop).

#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_edge_count(channel, reset_counter) ⇒ Object

Returns the current value of the edge counter for the selected channel. You can configure the edges that are counted with BrickletIO16V2#set_edge_count_configuration.

If you set the reset counter to true, the count is set back to 0 directly after it is read.

#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|

#get_monoflop(channel) ⇒ Object

Returns (for the given channel) the current value and the time as set by BrickletIO16V2#set_monoflop as well as the remaining time until the value flips.

end

#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

#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!

end

#set_all_input_value_callback_configuration(period, value_has_to_change) ⇒ Object

The period is the period with which the CALLBACK_ALL_INPUT_VALUE 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.

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.

end

#set_configuration(channel, direction, value) ⇒ Object

Configures the value and direction of a specific channel. Possible directions are ‘i’ and ‘o’ for input and output.

If the direction is configured as output, the value is either high or low (set as true or false).

If the direction is configured as input, the value is either pull-up or default (set as true or false).

For example:

  • (0, ‘i’, true) will set channel-0 as input pull-up.

  • (1, ‘i’, false) will set channel-1 as input default (floating if nothing is connected).

  • (2, ‘o’, true) will set channel-2 as output high.

  • (3, ‘o’, false) will set channel-3 as output low.

A running monoflop timer for the specific channel will be aborted if this function is called.

end

#set_edge_count_configuration(channel, edge_type, debounce) ⇒ Object

Configures the edge counter for a specific channel.

The edge type parameter configures if rising edges, falling edges or both are counted if the channel is configured for input. Possible edge types are:

  • 0 = rising

  • 1 = falling

  • 2 = both

Configuring an edge counter resets its value to 0.

If you don’t know what any of this means, just leave it at default. The default configuration is very likely OK for you.

end

#set_input_value_callback_configuration(channel, period, value_has_to_change) ⇒ Object

This callback can be configured per channel.

The period is the period with which the CALLBACK_INPUT_VALUE 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.

  send_request FUNCTION_SET_INPUT_VALUE_CALLBACK_CONFIGURATION, [channel, period, value_has_to_change], 'C L ?', 8, ''
end

#set_monoflop(channel, value, time) ⇒ Object

Configures a monoflop of the specified channel.

The second parameter is the desired value of the specified channel. A true means relay closed and a false means relay open.

The third parameter indicates the time that the channels should hold the value.

If this function is called with the parameters (0, 1, 1500) channel 0 will close and in 1.5s channel 0 will open again

A monoflop can be used as a fail-safe mechanism. For example: Lets assume you have a RS485 bus and a IO-16 Bricklet 2.0 connected to one of the slave stacks. You can now call this function every second, with a time parameter of two seconds and channel 0 closed. Channel 0 will be closed all the time. If now the RS485 connection is lost, then channel 0 will be opened in at most two seconds.

end

#set_selected_value(channel, value) ⇒ Object

Sets the output value of a specific channel without affecting the other channels.

A running monoflop timer for the specific channel will be aborted if this function is called.

.. note

This function does nothing for channels that are configured as input. Pull-up resistors can be switched on with BrickletIO16V2#set_configuration.

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_value(value) ⇒ Object

Sets the output value of all sixteen channels. A value of true or false outputs logic 1 or logic 0 respectively on the corresponding channel.

Use BrickletIO16V2#set_selected_value to change only one output channel state.

For example: (True, True, False, False, …, False) will turn the channels 0-1 high and the channels 2-15 low.

All running monoflop timers will be aborted if this function is called.

.. note

This function does nothing for channels that are configured as input. Pull-up resistors can be switched on with BrickletIO16V2#set_configuration.

end

#set_write_firmware_pointer(pointer) ⇒ Object

Sets the firmware pointer for BrickletIO16V2#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

Writes 64 Bytes of firmware at the position as written by BrickletIO16V2#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.

end

#write_uid(uid) ⇒ Object

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