Implementations

Creates an object with the unique device ID uid. This object can then be used after the IP Connection ip_connection is connected.

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 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 send and errors are silently ignored, because they cannot be detected.

See set_response_expected for the list of function ID constants available for this function.

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 send and errors are silently ignored, because they cannot be detected.

Changes the response expected flag for all setter and callback configuration functions of this device at once.

Possible extension types:

TypeDescription
1Chibi
2RS485
3WIFI
4Ethernet
5WIFI 2.0

The extension type is already set when bought and it can be set with the Brick Viewer, it is unlikely that you need this function.

Associated constants:

  • MASTERBRICK_EXTENSION_TYPE_CHIBI
  • MASTERBRICK_EXTENSION_TYPE_RS485
  • MASTERBRICK_EXTENSION_TYPE_WIFI

Sets up to 254 slave addresses. Valid addresses are in range 1-255. 0 has a special meaning, it is used as list terminator and not allowed as normal slave address. The address numeration (via \c num parameter) has to be used ascending from 0. For example: If you use the Chibi Extension in Master mode (i.e. the stack has an USB connection) and you want to talk to three other Chibi stacks with the slave addresses 17, 23, and 42, you should call with (0, 17), (1, 23), (2, 42) and (3, 0). The last call with (3, 0) is a list terminator and indicates that the Chibi slave address list contains 3 addresses in this case.

Returns the slave address for a given num as set by Set RS485 Slave Address.

Returns CRC error counts of the RS485 communication. If this counter starts rising, it is likely that the distance between the RS485 nodes is too big or there is some kind of interference.

Sets the configuration of the RS485 Extension. Speed is given in baud. The Master Brick will try to match the given baud rate as exactly as possible. The maximum recommended baud rate is 2000000 (2Mbit/s). Possible values for parity are ‘n’ (none), ‘e’ (even) and ‘o’ (odd). Possible values for stop bits are 1 and 2.

If your RS485 is unstable (lost messages etc.), the first thing you should try is to decrease the speed. On very large bus (e.g. 1km), you probably should use a value in the range of 100000 (100kbit/s).

The values are stored in the EEPROM and only applied on startup. That means you have to restart the Master Brick after configuration.

Associated constants:

2WEP
3No Encryption

The key has a max length of 50 characters and is used if encryption is set to 0 or 2 (WPA/WPA2 or WEP). Otherwise the value is ignored.

For WPA/WPA2 the key has to be at least 8 characters long. If you want to set a key with more than 50 characters, see Set Long Wifi Key.

For WEP the key has to be either 10 or 26 hexadecimal digits long. It is possible to set the WEP key_index (1-4). If you don’t know your key_index, it is likely 1.

If you choose WPA Enterprise as encryption, you have to set eap_options and the length of the certificates (for other encryption types these parameters are ignored). The certificate length are given in byte and the certificates themselves can be set with Set Wifi Certificate. eap_options consist of the outer authentication (bits 1-2), inner authentication (bit 3) and certificate type (bits 4-5):

OptionBitsDescription
outer authentication1-20=EAP-FAST
inner authentication30=EAP-MSCHAP
certificate type4-50=CA Certificate

Example for EAP-TTLS + EAP-GTC + Private Key: option = 2 | (1 << 2) | (2 << 3).

The values are stored in the EEPROM and only applied on startup. That means you have to restart the Master Brick after configuration.

StateDescription
0Disassociated
1Associated
2Associating
3Error
255Not initialized yet

  • MASTERBRICK_WIFI_STATE_ASSOCIATING
  • MASTERBRICK_WIFI_STATE_ERROR
  • MASTERBRICK_WIFI_STATE_NOT_INITIALIZED_YET

Refreshes the Wi-Fi status (see Get Wifi Status). To read the status of the Wi-Fi module, the Master Brick has to change from data mode to command mode and back. This transaction and the readout itself is unfortunately time consuming. This means, that it might take some ms until the stack with attached WIFI Extension reacts again after this function is called.

This function is used to set the certificate as well as password and username for WPA Enterprise. To set the username use index 0xFFFF, to set the password use index 0xFFFE. The max length of username and password is 32.

The certificate is written in chunks of size 32 and the index is used as the index of the chunk. data_length should nearly always be 32. Only the last chunk can have a length that is not equal to 32.

The starting index of the CA Certificate is 0, of the Client Certificate 10000 and for the Private Key 20000. Maximum sizes are 1312, 1312 and 4320 byte respectively.

The values are stored in the EEPROM and only applied on startup. That means you have to restart the Master Brick after uploading the certificate.

It is recommended to use the Brick Viewer to set the certificate, username and password.

Returns the certificate for a given index as set by Set Wifi Certificate.

Sets the power mode of the WIFI Extension. Possible modes are:

ModeDescription

  • MASTERBRICK_WIFI_POWER_MODE_LOW_POWER

Returns the power mode as set by Set Wifi Power Mode.

Associated constants:

  • MASTERBRICK_WIFI_POWER_MODE_FULL_SPEED
  • MASTERBRICK_WIFI_POWER_MODE_LOW_POWER

Returns informations about the Wi-Fi receive buffer. The Wi-Fi receive buffer has a max size of 1500 byte and if data is transfered too fast, it might overflow.

The return values are the number of overflows, the low watermark (i.e. the smallest number of bytes that were free in the buffer) and the bytes that are currently used.

You should always try to keep the buffer empty, otherwise you will have a permanent latency. A good rule of thumb is, that you can transfer 1000 messages per second without problems.

Try to not send more then 50 messages at a time without any kind of break between them.

Sets the regulatory domain of the WIFI Extension. Possible domains are:

Returns the USB voltage in mV. Does not work with hardware version 2.1.

Sets a long Wi-Fi key (up to 63 chars, at least 8 chars) for WPA encryption. This key will be used if the key in Set Wifi Encryption is set to -. In the old protocol, a payload of size 63 was not possible, so the maximum key length was 50 chars.

With the new protocol this is possible, since we didn’t want to break API, this function was added additionally.

The SPITF protocol can be used with a dynamic baudrate. If the dynamic baudrate is enabled, the Brick will try to adapt the baudrate for the communication between Bricks and Bricklets according to the amount of data that is transferred.

The baudrate will be increased exponentially if lots of data is send/received and decreased linearly if little data is send/received.

This lowers the baudrate in applications where little data is transferred (e.g. a weather station) and increases the robustness. If there is lots of data to transfer (e.g. Thermal Imaging Bricklet) it automatically increases the baudrate as needed.

In cases where some data has to transferred as fast as possible every few seconds (e.g. RS485 Bricklet with a high baudrate but small payload) you may want to turn the dynamic baudrate off to get the highest possible performance.

The maximum value of the baudrate can be set per port with the function Set SPITFP Baudrate. If the dynamic baudrate is disabled, the baudrate as set by Set SPITFP Baudrate will be used statically.

The minimum dynamic baudrate has a value range of 400000 to 2000000 baud.

By default dynamic baudrate is enabled and the minimum dynamic baudrate is 400000.

.. versionadded:: 2.4.6$nbsp;(Firmware)

Sets the baudrate for a specific Bricklet port (‘a’ - ‘d’). The baudrate can be in the range 400000 to 2000000.

If you want to increase the throughput of Bricklets you can increase the baudrate. If you get a high error count because of high interference (see Get SPITFP Error Count) you can decrease the baudrate.

If the dynamic baudrate feature is enabled, the baudrate set by this function corresponds to the maximum baudrate (see Set SPITFP Baudrate Config).

Regulatory testing is done with the default baudrate. If CE compatibility or similar is necessary in you applications we recommend to not change the baudrate.

The default baudrate for all ports is 1400000.

.. versionadded:: 2.4.3$nbsp;(Firmware)

Returns the baudrate for a given Bricklet port, see Set SPITFP Baudrate.

.. versionadded:: 2.4.3$nbsp;(Firmware)

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 Brick side. All Bricklets have a similar function that returns the errors on the Bricklet side.

Returns the temperature in °C/10 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 an accuracy of +-15%. Practically it is only useful as an indicator for temperature changes.

Calling this function will reset the Brick. Calling this function on a Brick inside of a stack will reset the whole stack.

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

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

The position can be ‘0’-‘8’ (stack position).
