Graphics Getting Started Application on SAM9X60 Curiosity Development Board

Launch MPLAB® X IDE- From the main menu, click on File, then New Project. Under “Projects” choose 32-bit MCC Harmony Project, click Next- For Framework Path choose the location on your PC where you want to download the Harmony 3 framework- Click Next.

Enter Location , Folder and Name of the project. Click Next.

In the Configuration Settings window, for Name enter lcdc_rgba8888_mxt_9x60_wvga, for Device Family select SAM, for Target Device select SAM9X60D1G. Click Finish.

This creates an empty project and set this project as main project if there are other projects open in the project explorer window.

From main menu, click on Tools -> Embedded -> MPLAB® Code Configurator or click MCC button in the MPLAB® X IDE tool bar. It will launch Content manger Wizard. Then select MPLAB® Harmony.

In addition to the required packages, download the optional packages gfx_sam9x60, bsp, csp, core, gfx, dev_packs and then click Finish. Content download will take some time. Please wait till all the contents are downloaded.

Now project graph will be displayed. From device resource add Board Support Packages for SAM9X60 Curiosity Kit BSP to Project Graph.

From device resource add Graphics -> Templates -> Legato Graphics w/PDA TM5000 Display to Project Graph. You will be prompted to allow auto-connection and auto-activation of several components- Click on Yes for all of them except “FreeRTOS”.

Choosing the Legato Graphics w/PDA TM5000 Display template automatically populates rest of the project components. This can be seen in the way the project graph is setup and connected.

In the project graph, click on Flexcom6. In the Configuration Options window, select clock speed as 100,000 (100KHz).

In the project graph, click on LE LCDC Driver. In the Configuration Options window, select output color mode as 18BPP.

From the project graph window, plugins menu select Pin Configuration.

You can see that PA30 and PA31 are set to FLEXCOM6. Enable pullups for those pins. Ensure all the pins are configured as below:

Now Save all. Then click generate code. This will generate code for all the peripherals that have been added in the project graph.

Now let us use Microchip Graphics Composer(MGC) to design the graphics to be displayed on the LCD screen and generate the legato library. From the Project graph -> plugin, launch Legato Graphics Composer. (From next software update, this plugin will be renamed to Microchip Graphics Composer)

From the window that pops-up, click on Create a new project using the new project wizard.

In the Display Configuration window, choose WVGA (800x480) for Presets and click on Apply. You will see that the Width and Height are updated. Click Next.

For Color Mode -> select RGBA_8888. Click Next. For Memory Profile -> select MPU. Click Next. In the Project Template window, select the Start with a basic quickstart project template checkbox. Click Next. Click Finish

You will see the following screen generated by the composer.

After the graphics display is composed, you can generate the design files by clicking the Generate Code from the File option in the main menu .

You can save the design files by clicking on File from the main menu and selecting Save As. Provide a filename with _design and save it in the ( That way the next time MGC is launched, the design file is automatically opened) and click Save.

You can now exit Microchip Graphics Composer by clicking on Exit from File option in the main menu.

From MCC, click on Generate Code. This will generate code for the quickstart template designed using Microchip Graphics Composer.

Lastly change the following code. In Legato -> renderer -> legato_renderer.c, add proper section for no cache attribute as shown below:
The .region_nocache memory location is defined in the linker file and lets the linker know which memory region is to be used for scratch buffers.

Now right click on the project and click Properties. For Connected Hardware Tool -> select connected hardware debugger used, for Compiler Toolchain -> select XC32 and click Apply.

From J-32 , Option categories choose Communication and for JTAG Method, select 4-wire JTAG.

Select Bootstrap for Categories and select the Use Bootstrap checkbox. For bootstrap file -> select the at91bootstrap elf file from here- Click on Apply and OK.

Clean and build the project. You should see a message on the output console that the project was successfully built. This completes the development of the basic graphics quickstart getting started application.
