Note
This Bricklet is currently in the prototype stage and the software/hardware as well as the documentation is in an incomplete state.
This is the description of the TCP/IP protocol for the Accelerometer Bricklet. General information and technical specifications for the Accelerometer Bricklet are summarized in its hardware description.
A general description of the TCP/IP protocol structure can be found here.
Function ID: | 1 |
---|---|
Request: | empty payload |
Response: |
|
Returns the acceleration in x, y and z direction. The values are given in mG (1/1000 G).
If you want to get the acceleration periodically, it is recommended to use the callback CALLBACK_ACCELERATION and set the period with set_acceleration_callback_period.
Function ID: | 8 |
---|---|
Request: | empty payload |
Response: |
|
Returns the temperature of the accelerometer in °C.
Function ID: | 11 |

Request: | empty payload |
Response: | no response |
Enables the LED on the Bricklet.
Function ID: | 12 |
---|---|
Request: | empty payload |
Response: | no response |
Disables the LED on the Bricklet.
Function ID: | 13 |
---|---|
Request: | empty payload |
Response: |
|
Returns true if the LED is enabled, false otherwise.
Function ID: | 9 |

Request: |
|
Response: | no response |
Configures the data rate, full scale range and filter bandwidth. Possible values are:
Decreasing data rate or full scale range will also decrease the noise on the data.
The default values are 100Hz data rate, -4G to +4G range and 200Hz filter bandwidth.
Function ID: | 10 |
---|---|
Request: | empty payload |
Response: |
|
Returns the configuration as set by set_configuration.
Function ID: | 255 |
---|---|
Request: | empty payload |
Response: |
|
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' or 'd'.
The device identifier numbers can be found here.
Function ID: | 2 |
---|---|
Request: |
|
Response: | no response |
Sets the period in ms with which the CALLBACK_ACCELERATION callback is triggered periodically. A value of 0 turns the callback off.
CALLBACK_ACCELERATION is only triggered if the acceleration has changed since the last triggering.
The default value is 0.
Function ID: | 3 |
---|---|
Request: | empty payload |
Response: |
|
Returns the period as set by set_acceleration_callback_period.
Function ID: | 4 |
---|---|
Request: |
|
Response: | no response |
Sets the thresholds for the CALLBACK_ACCELERATION_REACHED callback.
The following options are possible:
Option | Description |
---|---|
'x' | Callback is turned off |
'o' | Callback is triggered when the temperature is outside the min and max values |
'i' | Callback is triggered when the temperature is inside the min and max values |
'<' | Callback is triggered when the temperature is smaller than the min value (max is ignored) |
'>' | Callback is triggered when the temperature is greater than the min value (max is ignored) |
The default value is ('x', 0, 0, 0, 0, 0, 0).
Function ID: | 5 |
---|---|
Request: | empty payload |
Response: |
|
Returns the threshold as set by set_acceleration_callback_threshold.
Function ID: | 6 |
---|---|
Request: |
|
Response: | no response |
Sets the period in ms with which the threshold callback
is triggered, if the threshold
keeps being reached.
The default value is 100.
Function ID: | 7 |
---|---|
Request: | empty payload |
Response: |
|
Returns the debounce period as set by set_debounce_period.
Function ID: | 14 |
---|---|
Response: |
|
This callback is triggered periodically with the period that is set by set_acceleration_callback_period. The response values are the X, Y and Z acceleration.
CALLBACK_ACCELERATION is only triggered if the acceleration has changed since the last triggering.
Function ID: | 15 |
---|---|
Response: |
|
This callback is triggered when the threshold as set by set_acceleration_callback_threshold is reached. The response values are the X, Y and Z acceleration.
If the threshold keeps being reached, the callback is triggered periodically with the period as set by set_debounce_period.
