openHAB - Master Brick

Warning

The openHAB bindings are still in beta, but the development was stopped.

This is the description of the openHAB API bindings for the Master Brick. General information and technical specifications for the Master Brick are summarized in its hardware description.

An installation guide for the openHAB API bindings is part of their general description.

Thing

UID:
  • tinkerforge:brickmaster:[UID]
Required firmware version:
  • 2.4.2
Firmware update supported:
  • no
Channels:
Actions:
Parameters:
  • Status LED Configuration – Type: boolean, Default: true
  • The status LED is the blue LED next to the USB connector. If enabled is is on and it flickers if data is transfered. If disabled it is always off.

  • SPITFP Enable Dynamic Baudrate – Type: boolean, Default: true
  • 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 sent/received and decreased linearly if little data is sent/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. If the dynamic baudrate is disabled, the maximum baudrate will be used statically.

  • SPITFP Minimum Dynamic Baudrate – Type: integer, Default: 400000, Min: 400000, Max: 2000000
  • See SPITFP Enable Dynamic Baudrate

  • (Maximum) SPITFP Baudrate Port A – Type: integer, Default: 1400000, Min: 400000, Max: 2000000
  • The baudrate for Bricklet port A. 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 you can decrease the baudrate. If the dynamic baudrate feature is enabled, this is the maximum baudrate. Regulatory testing is done with the default baudrate. If CE compatibility or similar is necessary in your applications we recommend to not change the baudrate.

  • (Maximum) SPITFP Baudrate Port B – Type: integer, Default: 1400000, Min: 400000, Max: 2000000
  • The baudrate for Bricklet port B. 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 you can decrease the baudrate. If the dynamic baudrate feature is enabled, this is the maximum baudrate. Regulatory testing is done with the default baudrate. If CE compatibility or similar is necessary in your applications we recommend to not change the baudrate.

  • (Maximum) SPITFP Baudrate Port C – Type: integer, Default: 1400000, Min: 400000, Max: 2000000
  • The baudrate for Bricklet port C. 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 you can decrease the baudrate. If the dynamic baudrate feature is enabled, this is the maximum baudrate. Regulatory testing is done with the default baudrate. If CE compatibility or similar is necessary in your applications we recommend to not change the baudrate.

  • (Maximum) SPITFP Baudrate Port D – Type: integer, Default: 1400000, Min: 400000, Max: 2000000
  • The baudrate for Bricklet port D. 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 you can decrease the baudrate. If the dynamic baudrate feature is enabled, this is the maximum baudrate. Regulatory testing is done with the default baudrate. If CE compatibility or similar is necessary in your applications we recommend to not change the baudrate.

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.

brickMasterGetWifiCertificate(int index)
Parameters:

  • used – Type: int, Unit: 1 B, Range: [0 to 1500]

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.
