QEIV2 ABZ Encoder Oneshot Mode
============================================================

Overview
--------

**Qeiv2 ABZ Encoder Oneshot Mode**  project demonstrates configuring the ABZ encoder and obtaining its data using oneshot mode, then printing the data through a serial console.

Configurations
--------------

- Install the serial terminal, view  :ref:`board information <board_resource>` , and configure the serial terminal parameters

- This program uses the **BLM57050-1000**  brushless motor of "Leisai Intelligence", refer to the `Leisai Intelligence <https://leisai.com/>`_ website for the specific parameters of the motor.

- Click   :ref:`DRV-LV50A-MP1907 Motor Driver Board <drv_lv50a_mp1907>`   section and configure

Running the Demo
----------------

- Power on, open the serial terminal, log as following:

- Rotating the motor will trigger an interrupt in the encoder's calculation of speed, then printing the following information.
