Introduction<\/span><\/strong><\/p>\n

The Raspberry Pi is a series of credit card-sized single-board computers developed in the United Kingdom by the Raspberry Pi Foundation to promote the teaching of basic computer science in schools and in developing countries.The original model became far more popular than anticipated, selling outside of its target market for uses such as robotics.<\/span><\/p>\n

The PTHAT has been designed to fit directly onto the Raspberry Pi expansion connector and complies to the Raspberry Pi HAT specifications.<\/span><\/p>\n

The Raspberry Pi can run a number of different operating systems and the popular one is\u00a0RASPBIAN JESSIE WITH PIXEL .<\/span><\/p>\n

This is Linux with a Windows GUI and has a number of different development options, with Python being the main one used by devlopers.<\/span><\/p>\n

Windows 10 IoT Core is a new edition of Windows targeted towards small embedded devices and maker boards such as Raspberry Pi2 or Pi3. IoT core is designed to work with low-level bus interfaces such as Serial, I2C, SPI, USB. You can write a Universal Windows Application using a variety of programming languages in Visual Studio to rapidly create maker projects.<\/span><\/p>\n

Running a dedicated application in a Windows 10 sandbox is pretty cool and more information can be found on the following link which includes how to setup the development environment for your Raspberry Pi<\/span><\/p>\n

We have created an example application using Visual Studio 2015 that can be used with Windows 10 IOT.<\/span>
\nThe example has been written in C# as a Universal Windows Platform (UWP).<\/span><\/p>\n

This allows you to send commands using the serial port and covers the Instant Commands that are shown on the Command Set Page<\/a>.\u00a0Also it automatically formats the commands to the correct syntax.\u00a0<\/span><\/p>\n

Please use the following link to download the full source code.\u00a0<\/span><\/p>\n

To go through every step of setting up Visual Studio 2015 development environment with Windows 10 IOT is a big task and no point repeating it here as there is already good existing information.<\/span>
\nA good starting place is Microsoft’s own site
\nhttps:\/\/docs.microsoft.com\/en-us\/windows\/iot-core\/tutorials\/rpi<\/a>
\n<\/span><\/p>\n

Once you have your Raspberry Pi computer setup with the Windows 10 IOT image and Visual Studio configured, the you will be able to simply load the example application we have provided and start to send commands back and forth to the PTHAT.<\/span><\/p>\n

When you launch the application it should enumerate the serial ports on your Raspberry Pi and list them in the top box.<\/span><\/p>\n

1.) Highlight the Serial Port.<\/span><\/p>\n

2.) Click the Connect button.<\/span><\/p>\n

[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row admin_label=”row”][et_pb_column type=”1_2″][et_pb_image admin_label=”Image” src=”https:\/\/pthat.com\/wp-content\/uploads\/2016\/12\/SESC-2.jpg” url_new_window=”off” animation=”right” show_in_lightbox=”off” use_overlay=”off” sticky=”off” align=”left” force_fullwidth=”off” always_center_on_mobile=”on” use_border_color=”off” border_color=”#ffffff” border_style=”solid”] [\/et_pb_image][\/et_pb_column][et_pb_column type=”1_2″][et_pb_divider admin_label=”Divider” color=”#ffffff” show_divider=”off” height=”70″] [\/et_pb_divider][et_pb_text admin_label=”Text” background_layout=”light” text_orientation=”left” use_border_color=”off” border_color=”#ffffff” border_style=”solid”]<\/p>\n

Once connected you will find that all the buttons at the bottom of the application will become enabled and the Read Data box will display Waiting for data..<\/span>
\nYou are now ready to send commands.<\/span><\/p>\n

Each Axis has to be set before it can be started and in the example we have listed individual settings for the X,Y,Z and E Axis’s.<\/span><\/p>\n

The following settings can be set:<\/span><\/p>\n

Frequency: Sets the speed of the pulse train<\/span>
\n Pulse Count: Sets the required amount of pulses to be sent out<\/span>
\n Direction: Sets motor direction 0=CW 0=CCW<\/span>
\n Ramp UP: See command Set page for more details.<\/span>
\n Ramp Down: See command Set page for more details.<\/span>
\n Ramp Divide: See command Set page for more details.<\/span>
\n Ramp Pause: See command Set page for more details.<\/span>
\n Link to ADC: See command Set page for more details.<\/span>
\n Enable Polarity: See command Set page for more details.<\/span><\/p>\n

1.) Click Set button<\/span><\/p>\n

2.) Once set you will see that the Start button has been enabled.<\/span><\/p>\n

Also while the pulse train is running, you can send other request commands such as requesting the amount of pulses that have been sent out so far, the value of the ADC’s etc.<\/span><\/p>\n

The Read Data box will be updated with the replies from the PTHAT.<\/span><\/p>\n

You can of course select more than one Axis to set and start at the same time or even start then at different times while the others are running.<\/span><\/p>\n

Just choose Set for each Axis and the click on Start All.<\/span><\/p>\n
