class
pyupm_mma8x5x.MMA8X5X(bus, params=None, devAddr=29)[source]¶ Bases:
objectAPI for the MMA8X5X Three-Axis Accelerometer.
ID: mma8x5x
Name: MMA8X5X Three-Axis Accelerometer
Other Chips: mma8451 mma8452 mma8453 mma8652 mma8653
Category: accelerometer compass
Manufacturer: freescale
Link:http://www.nxp.com/products/sensors/accelerometers:DRSNSAXLRTN
Connection: i2c Description in web-link above: The NXP MMA8X5X are low-power, three-axis capacitive micromachined accelerometer with 10/12/14 bits of resolution. These accelerometer are packed with embedded functions with flexible user-programmable options configurable to two interrupt pins. The MMA8X5X have user-selectable full scales of +-2g/+-4g/+-8g.
C++ includes: mma8x5x.hpp

getData(data, bSampleData=0)[source]¶ int getData(mma8x5x_data_t *data, int bSampleData=0)
Get sensor values
data: Sensor values
bSampleData: Flag to read sensor
0 on success -1 on error
-
getX(bSampleData=0)[source]¶ int16_t getX(int bSampleData=0)
Get x-axis acceleration
bSampleData: Flag to read sensor
The x-axis acceleration on success -999 on error
-
getY(bSampleData=0)[source]¶ int16_t getY(int bSampleData=0)
Get y-axis acceleration
bSampleData: Flag to read sensor
The y-axis acceleration on success -999 on error
-
getZ(bSampleData=0)[source]¶ int16_t getZ(int bSampleData=0)
Get z-axis acceleration
bSampleData: Flag to read sensor
The z-axis acceleration on success -999 on error
-
isReady()[source]¶ int isReady(void)
Check for new set of measurement data.
MMA8X5X_DATA_READY if new sample is ready MMA8X5X_NODATA if nothing is available
-
sampleData()[source]¶ int sampleData(void)
Read & calculate accelerometer data in mg & saves them to variables
0 on success -1 on error
-
setActive()[source]¶ int setActive(void)
Set active mode, this enables periodic measurements
0 on success -1 on error
-
setDeviceName(type)[source]¶ int setDeviceName(uint8_t type)
Set device name and type matching given type or read out devive_id to set name and type of device
type: Type of device if set or 0 if needed to find out by it
0 on success -1 on error
-
setDeviceParams(params)[source]¶ int setDeviceParams(mma8x5x_params_t *params)
Set device params to given data or set default params and read out devive_id to set type of device
params: Params of device if set by user NULL if it is not set by user
0 on success -1 on error
-
setStandby()[source]¶ int setStandby(void)
Set standby mode, this disables periodic measurements
0 on success -1 on error
-
setUserOffset(x, y, z)[source]¶ int setUserOffset(int8_t x, int8_t y, int8_t z)
Set user offset correction Offset correction register will be erased after accelerometer reset
x: Offset correction value for x-axis
y: Offset correction value for y-axis
z: Offset correction value for z-axis
0 on success -1 on error
