Return value
SimReset1G
No additional information
Parameters
- This macro has no parameters
Return value
- This call does not return a value
UpdateCompassData
Reads from the compass and updates the local XYZ variables.
Returns 1 for new data and 0 for no new data
Parameters
- This macro has no parameters
Return value
Write_Register
Writes a data value to a specific register on the accelerometer
Parameters
- BYTE Reg
- BYTE Data
Return value
SimSetAccelerometer
Allows the XYZ slider values to be set via the simulation
Parameters
- INT X
- INT Y
- INT Z
Return value
- This call does not return a value
CollectXYZData
Collect the data from the local accelerometer buffers.
The Axis parameter specifies the Axis to be read.
0 / 'x' / 'X' - X axis
1 / 'y' / 'Y' - Y axis
2 / 'z' / 'Z' - Z axis
Parameters
- BYTE Axis
Return value
UpdateAccelerometerData
Reads from the accelerometer and updates the local XYZ variables.
Returns 1 for new data and 0 for no new data
Parameters
- This macro has no parameters
Return value
SimSetCompass
Allows the XYZ slider values to be set via the simulation
Parameters
- INT X
- INT Y
- INT Z
Return value
- This call does not return a value
Read_Bearing
Reads the current sensor compass bearing based on degrees CW from magnetic north.
Returns 0-359 where 0 = North, 90 = East, 180 = South, 270 = West
Requires the ArcTan floating point function to be available to work correctly.
Supported on AVR, 16-bit
Parameters
- BYTE NumSamples
- The number of readings to base the bearing on
Return value
Initialise
Sets up up the communication bus and initialises the accelerometer module.
Returns 0 for success and > 0 for fail.
Parameters
- This macro has no parameters
Return value

Property reference
Bit Depth
This property is of type Signed integer and can be referenced with the variable name bit_depth.
No additional information
Accel Data Rate
This property is of type Fixed list of ints and can be referenced with the variable name accel_data_rate.
No additional information
Accel Scale
This property is of type Fixed list of ints and can be referenced with the variable name accel_scale.
No additional information
Compass Data Rate
This property is of type Fixed list of ints and can be referenced with the variable name compass_data_rate.
No additional information
Compass Scale
This property is of type Fixed list of ints and can be referenced with the variable name compass_scale.
No additional information
Channel
This property is of type Fixed list of ints and can be referenced with the variable name cal_i2c::CHANNEL.
Channel selection
Baud Select
This property is of type Fixed list of ints and can be referenced with the variable name cal_i2c::BAUD_LIST.
Baud rate option selector
Baud Rate
This property is of type Signed integer and can be referenced with the variable name cal_i2c::BAUD.
Baud rate to be used
Stop Delay
This property is of type True or false and can be referenced with the variable name cal_i2c::StopDel.
On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not
a 10ms delay between an I2C stop event and the next I2C start event.
Most modern microcontrollers will not have a problem so this property can be disabled to speed up the
I2C communications.
SDA
This property is of type Single digital pin and can be referenced with the variable name cal_i2c::SDA.
Pin used for SDA (data signal)
SCL
This property is of type Single digital pin and can be referenced with the variable name cal_i2c::SCL.
Pin used for SCL (clock signal)
Simulation GUI
This property is of type True or false and can be referenced with the variable name SimulationGUI.
Yes: Accelerometer data will come from the simulation component sliders.
No: Accelerometer data will come from the I2C CAL component - Injector etc
Scope Traces
This property is of type True or false and can be referenced with the variable name cal_i2c::ScopeTraces.
Selects if the scope traces are automatically generated or not
Console Data
This property is of type True or false and can be referenced with the variable name cal_i2c::ConsoleData.
Selects if the console data is automatically generated or not
Injector
This property is of type Fixed list of ints and can be referenced with the variable name cal_i2c::Injector.
