Pytrack API
This chapter describes the various libraries which are designed for the Pytrack board. This
includes details about the various methods and classes available for each of the Pytrack’s
sensors.
3-Axis Accelerometer (LIS2HH12)
Pytrack has a 3-Axis Accelerometer that provides outputs for acceleration as well as roll,
pitch and yaw.
Constructors
class LIS2HH12(pytrack = None, sda = 'P22', scl = 'P21')
Creates a
LIS2HH12
object, that will return values for acceleration, roll, pitch and yaw.
Constructor must be passed a Pytrack or I2C object to successfully construct.
Methods
LIS2HH12.acceleration()
Read the acceleration from the
LIS2HH12
. Returns a tuple with the 3 values of acceleration
(G).
LIS2HH12.roll()
Read the current roll from the
LIS2HH12
. Returns a float in degrees in the range -180 to
180.
LIS2HH12.pitch()
Read the current pitch from the
LIS2HH12
. Returns a float in degrees in the range -90 to 90.
Once the board tilts beyond this range the values will repeat. This is due to a lack of yaw
measurement, making it not possible to know the exact orientation of the board.
GPS with GLONASS (Quectel L76-L GNSS)
Pytrack has a GPS (with GLONASS) that provides outputs longitude/latitude, speed and
other information about the Pytrack's location.
