CollectXYZData
|
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 | |
 - BYTE
|
Axis |
 - INT
|
Return |
Initialise
|
|
Initialise |
| Sets up up the communication bus and initialises the accelerometer module. Returns 0 for success and > 0 for fail. | |
| - BYTE
|
Return |
SimReset1G
|
|
SimReset1G |
| Resets the simulation to 0.0 on X and Y and 1.0 on Z as if the accelerometer was sitting completely horizontal. | |
 - VOID
|
Return |
SimSetXYZ
|
|
SimSetXYZ |
| Allows the XYZ slider values to be set via the simulation | |
| - INT
|
X |
| - INT
|
Y |
| - INT
|
Z |
| - VOID
|
Return |
UpdateXYZData
|
|
UpdateXYZData |
| Reads from the accelerometer and updates the local XYZ variables. Returns 1 for new data and 0 for no new data | |
| - BYTE
|
Return |
Property reference
|
Properties |
|
Bit Depth |
| The number of binary bits used to store the sensor's X,Y,Z readings. | |
|
Bus Type |
| The interface used to talk to the accelerometer. I2C - Two Wire Interface SDA / SCL SPI - Four Wire Interface MISO / MOSI / SCK / CS | |
|
|
Data Rate |
| Configures how often the sensor collects a new reading. More often = better instant reaction to new events Less often = more stable results | |
|
|
Scale |
| The accelerometer readings are scaled based on the maximum amount of G force the sensor can represent. 6G = Bigger gravitational force 2G = Higher resolution | |
|
|
Int Option |
| Sets if we use the interrupt pin to check if new data is available | |
|
|
Power Option |
| Sets if the sensor is always powered or powered via a microcontroller output pin. | |
|
Connections |
|
|
SPI Connections |
|
|
Channel |
| SPI Channel selector | |
|
|
Prescale |
| Prescale option selector | |
|
MOSI |
| SPI Data Out Pin SDO - Also Known as Master Out Slave In (MOSI) when used in Master mode. | |
|
|
MISO |
| SPI Data In Pin SDI - Also Known as Master In Slave Out (MISO) when used in Master mode. | |
|
|
CLK |
| SPI Clock Pin CLK - The Clock signal is driven by the SPI master. | |
|
|
CS / SS |
| Chip Select / Slave Select Pin Master Mode: General purpose output pin used to select the remote SPI device. Slave Mode: Hardware chip select pin input used to select the SPI device. | |
|
|
Simulation |
|
Simulation Coms |
| Yes: Accelerometer data will come from the simulation component sliders. No: Accelerometer data will come from the CAL component - I2C or SPI - API etc | |
