Now, for powering up the ARIES v2 board via the USB port of a Laptop\/Desktop\/PC and burning the code into the ARIES v2 board, we have to use a micro USB type B to USB type A cable. The cable should be connected to UART-0 port of the ARIES v2 board, and the Laptop\/Desktop\/PC should be preinstalled with Arduino IDE and VEGA ARIES boards of latest version.
<\/figcaption><\/figure>\n\n\n\nProcedure:
<\/h2>\n\n\n\nOpen Arduino IDE<\/p>\n\n\n\n
Go to Tools -> Board -> VEGA Processor ARIES Boards -> Select ARIES v2<\/p>\n\n\n\n
Go to Tools -> Programmer -> Select VEGA XMODEM<\/p>\n\n\n\n
Connect the ARIES v2 board to PC<\/p>\n\n\n\n
Go to Tools -> Port -> Select the appropriate port<\/p>\n\n\n\n

Download the Required Library for running this demo from the below given link:<\/p>\n\n\n\n
Required Library: https:\/\/gitlab.com\/riscv-vega\/vega-sensor-libraries\/display\/nhd_display <\/p>\n\n\n\n
For adding this library you can either extract the zip file inside Arduino<\/strong> folder or you can follow the below step:<\/p>\n\n\n\n
Go to Sketch -> Include Libraries -> Add .ZIP Library -> Go to the folder where you have downloaded nhd_display library -> Select your Library zip file -> Click OK.<\/p>\n\n\n\n
![\"\"](\"https:\/\/vegaprocessors.in\/blog\/wp-content\/uploads\/2023\/07\/addlib.png\")
<\/figure>\n\n\n\nAfter adding the library,<\/p>\n\n\n\n
Open File -> Examples -> Examples for ARIES v2 -> SPI -> Open NHD_HelloWorld<\/strong> example<\/p>\n\n\n\n
![\"\"](\"https:\/\/vegaprocessors.in\/blog\/wp-content\/uploads\/2023\/07\/nhdex.png\")
<\/figure>\n\n\n\nCompile and Upload the code <\/p>\n\n\n\n
![\"\"](\"https:\/\/vegaprocessors.in\/blog\/wp-content\/uploads\/2023\/07\/cu-1024x621.png\")
<\/figure>\n\n\n\nOutput<\/h2>\n\n\n\n
Once you\u2019ve completed the code, upload it to your ARIES v2.0 board using the Arduino IDE. Wait until the program is uploaded. After completing the uploading the program will start to execute.The NHD display Screen shows “Hello World” in display as follows:<\/p>\n\n\n\n
![\"\"](\"https:\/\/vegaprocessors.in\/blog\/wp-content\/uploads\/2023\/07\/nhdOp.png\")
<\/figure>\n\n\n\nOnce you have done this program, you can try the other example provided.<\/p>\n\n\n\n
More Examples<\/h2>\n\n\n\n
Open File -> Examples -> Examples for ARIES v2 -> SPI -> Open NHD_Display_Demo<\/strong> example<\/p>\n\n\n\n
![\"\"](\"https:\/\/vegaprocessors.in\/blog\/wp-content\/uploads\/2023\/07\/nhdex1.png\")
<\/figure>\n\n\n\nCompile and Upload the code <\/p>\n\n\n\n
Output:<\/h2>\n\n\n\n
Upload the above NHD_Display_Demo code to your ARIES v2.0 board using the Arduino IDE. Wait until the program is uploaded. Once the uploading is done, program will start to execute. The NHD display Screen will displays as follows:<\/p>\n\n\n\n

<\/figure>\n\n\n\nSince this is a touch display you can use this in your IoT projects for controlling different objects. Once the code is uploaded all the widgets will be in red colour indicating all the associated objects are turned OFF and when you touch any of the widgets provided it will turn into green colour indicating that the corresponding widget is ON. <\/p>\n\n\n\n
