- .. currentmodule:: pyb
- .. _pyb.Accel:
- class Accel -- accelerometer control
- ====================================
- Accel is an object that controls the accelerometer. Example usage::
- accel = pyb.Accel()
- for i in range(10):
- print(accel.x(), accel.y(), accel.z())
- Raw values are between -32 and 31.
- Constructors
- ------------
- .. class:: pyb.Accel()
- Create and return an accelerometer object.
-
- Methods
- -------
- .. method:: Accel.filtered_xyz()
- Get a 3-tuple of filtered x, y and z values.
- Implementation note: this method is currently implemented as taking the
- sum of 4 samples, sampled from the 3 previous calls to this function along
- with the sample from the current call. Returned values are therefore 4
- times the size of what they would be from the raw x(), y() and z() calls.
- .. method:: Accel.tilt()
- Get the tilt register.
- .. method:: Accel.x()
- Get the x-axis value.
- .. method:: Accel.y()
- Get the y-axis value.
- .. method:: Accel.z()
- Get the z-axis value.
- Hardware Note
- -------------
- The accelerometer uses I2C bus 1 to communicate with the processor. Consequently
- when readings are being taken pins X9 and X10 should be unused (other than for
- I2C). Other devices using those pins, and which therefore cannot be used
- concurrently, are UART 1 and Timer 4 channels 1 and 2.
