Most functions of the C/C++ bindings for microcontrollers return an error code
(e_code
).
Possible error codes are:
(as defined in errors.h
) as well as the errors returned from
the hardware abstraction layer (HAL) that is used.
Use :cpp:func`tf_hal_strerror` (defined in the HAL's header file) to get an error string for an error code.
Data returned from the device, when a getter is called,
is handled via output parameters. These parameters are labeled with the
ret_
prefix. The bindings will not write to an output parameter if NULL or nullptr
is passed. This can be used to ignore outputs that you are not interested in.
None of the functions listed below are thread-safe. See the API bindings description for details.

|
---|---|
Output Parameters: |

tf_industrial_analog_out_v2_set_out_led_config
(TF_IndustrialAnalogOutV2 *industrial_analog_out_v2, uint8_t config)¶Parameters: |
|
---|---|
Returns: |
|
You can turn the Out LED off, on or show a heartbeat. You can also set the LED to "Out 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 output value (voltage or current).
You can configure the channel status behavior with tf_industrial_analog_out_v2_set_out_led_status_config()
.
The following constants are available for this function:
For config:
tf_industrial_analog_out_v2_get_out_led_config
(TF_IndustrialAnalogOutV2 *industrial_analog_out_v2, uint8_t *ret_config)¶Parameters: |
|
---|---|
Output Parameters: |
|
Returns: |
|
Returns the Out LED configuration as set by tf_industrial_analog_out_v2_set_out_led_config()
The following constants are available for this function:
For ret_config:
tf_industrial_analog_out_v2_set_out_led_status_config
(TF_IndustrialAnalogOutV2 *industrial_analog_out_v2, uint16_t min, uint16_t max, uint8_t config)¶Parameters: |
|
---|---|
Returns: |
|
Sets the Out LED status config. This config is used if the Out LED is
configured as "Out Status", see tf_industrial_analog_out_v2_set_out_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 or µA above which the LED should turn on and set the "max" parameter to 0. Example: If you set a positive threshold of 5V, the LED will turn on as soon as the output value exceeds 5V and turn off again if it goes below 5V. For a negative threshold set the "max" parameter to the threshold value in mV or µA below which the LED should turn on and set the "min" parameter to 0. Example: If you set a negative threshold of 5V, the LED will turn on as soon as the output value goes below 5V and the LED will turn off when the output value exceeds 5V.
In intensity mode you can define a range mV or µA that is used to scale the brightness of the LED. Example with min=2V, max=8V: The LED is off at 2V and below, on at 8V and above and the brightness is linearly scaled between the values 2V and 8V. If the min value is greater than the max value, the LED brightness is scaled the other way around.

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.
The following constants are available for this function:

Output Parameters: |
|
Returns: |
|
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 Isolator Bricklet is always at position 'z'.
The device identifier numbers can be found here. There is also a constant for the device identifier of this Bricklet.
Virtual functions don't communicate with the device itself, but operate only on the API bindings device object.
tf_industrial_analog_out_v2_get_response_expected
(TF_IndustrialAnalogOutV2 *industrial_analog_out_v2, uint8_t function_id, bool *ret_response_expected)¶Parameters: |
|
---|---|
Output Parameters: |
|
Returns: |
|
Returns the response expected flag for the function specified by the function ID parameter. It is true if the function is expected to send a response, false otherwise.
For getter functions this is enabled by default and cannot be disabled,
because those functions will always send a response. For callback configuration
functions it is enabled by default too, but can be disabled by
tf_industrial_analog_out_v2_set_response_expected()
. For setter functions it is disabled by default
and can be enabled.
Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is sent and errors are silently ignored, because they cannot be detected.
The following constants are available for this function:
For function_id:
tf_industrial_analog_out_v2_set_response_expected
(TF_IndustrialAnalogOutV2 *industrial_analog_out_v2, uint8_t function_id, bool response_expected)¶Parameters: |
|
---|---|
Returns: |
|
Changes the response expected flag of the function specified by the function ID parameter. This flag can only be changed for setter (default value: false) and callback configuration functions (default value: true). For getter functions it is always enabled.
Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is sent and errors are silently ignored, because they cannot be detected.
The following constants are available for this function:
For function_id:
tf_industrial_analog_out_v2_set_response_expected_all
(TF_IndustrialAnalogOutV2 *industrial_analog_out_v2, bool response_expected)¶Parameters: |
|
---|---|
Returns: |
|
Changes the response expected flag for all setter and callback configuration functions of this device at once.
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.
tf_industrial_analog_out_v2_set_bootloader_mode
(TF_IndustrialAnalogOutV2 *industrial_analog_out_v2, uint8_t mode, uint8_t *ret_status)¶Parameters: |
|
---|---|
Output Parameters: |
|
Returns: |
|
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 constants are available for this function:
For mode:
For ret_status:
tf_industrial_analog_out_v2_get_bootloader_mode
(TF_IndustrialAnalogOutV2 *industrial_analog_out_v2, uint8_t *ret_mode)¶Parameters: |
|
---|---|
Output Parameters: |
|
Returns: |
|
Returns the current bootloader mode, see tf_industrial_analog_out_v2_set_bootloader_mode()
.

tf_industrial_analog_out_v2_set_write_firmware_pointer
(TF_IndustrialAnalogOutV2 *industrial_analog_out_v2, uint32_t pointer)¶Parameters: |
|
---|---|
Returns: |
|
Sets the firmware pointer for tf_industrial_analog_out_v2_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.
tf_industrial_analog_out_v2_write_firmware
(TF_IndustrialAnalogOutV2 *industrial_analog_out_v2, const uint8_t data[64], uint8_t *ret_status)¶Parameters: |
|
---|---|
Output Parameters: |
|
Returns: |
|
Writes 64 Bytes of firmware at the position as written by
tf_industrial_analog_out_v2_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.
tf_industrial_analog_out_v2_write_uid
(TF_IndustrialAnalogOutV2 *industrial_analog_out_v2, uint32_t uid)¶Parameters: |
|
---|---|
Returns: |
|

We recommend that you use Brick Viewer to change the UID.
tf_industrial_analog_out_v2_read_uid
(TF_IndustrialAnalogOutV2 *industrial_analog_out_v2, uint32_t *ret_uid)¶Parameters: |
|
---|---|
