# 2.1 MCLV2 Development Board Setup for Quadrature Encoder

## Setting Up the Hardware

The following table shows the target hardware for the application projects.

Project Name | Description
--- | ---
mclv2_sam_rh707_pim.X | MCLV2 Development Board ATSAMRH707 Plug-in module Hurst Motor with encoder

### Setting Up MCLV2 Development Board

- Mount the ATSAMRH707 Motor Control Plug In Module on U9 header.
- Place the “External Opamp Configuration” Matrix board at J14
- Motor Connections:
  - Phase U - M1 (White colored wire)
  - Phase V - M2 (Black colored wire)
  - Phase W - M3 (Red colored wire)

- Encoder Connections: Connect encoder wires as shown below

  - 1 : +5V (Red colored wire)
  - 2 : HA (White colored wire)
  - 3 : HB (Blue colored wire)
  - 8 : GND (Black colored wire)
- Jumper Settings:
  - JP1 - Curr, JP2 - Curr, JP3 - Curr
  - In order to use RS232 port for X2CScope Communication JP4 - UART, JP5 - UART
  - In order to use USB port for X2CScope Communication JP4 - USB, JP5 - USB
- Power the board with a 24V DC supply using J2 or BP1-BP2. For additional safety, it is recommended to use a current limited power supply while testing this software demonstration on a non-default hardware and motor.
- Complete Setup

## Running the Application

1. Build and Program the application using its IDE
2. Press switch S3 to start the motor
3. Vary potentiometer to change the speed of the motor
4. Press switch S3 to stop the motor
5. Press switch S2 to change the direction of the motor
6. Press switch S3 again to start the motor
7. Monitor graphs on X2C Scope

Refer to the following tables for switch and LED details:

Switch | Description

Switch S3 | To start or stop the motor.
Switch S2 | To change the direction of rotation. Direction toggle command is accepted only when motor is stationary.

LED D2 Status | Description
--- | ---
OFF | Motor spin direction is “positive”.
ON | Motor spin direction is “negative”.

LED D17 Status | Description
--- | ---
OFF | No fault.
ON | Fault is detected.
