+
+Magnetic hall angle sensor support for reading stepper motor angle
+shaft measurements using a1333, as5047d, or tle5012b SPI chips.  The
+measurements are available via the [API Server](API_Server.md) and
+[motion analysis tool](Debugging.md#motion-analysis-and-data-logging).
+
+```
+[angle my_angle_sensor]
+sensor_type:
+#   The type of the magnetic hall sensor chip. Available choices are
+#   "a1333", "as5047d", and "tle5012b". This parameter must be
+#   specified.
+#sample_period: 0.000400
+#   The query period (in seconds) to use during measurements. The
+#   default is 0.000400 (which is 2500 samples per second).
+cs_pin:
+#   The SPI enable pin for the sensor. This parameter must be provided.
