PSoC 62S2 Wi-Fi BT Pioneer Kit (CY8CKIT-062S2-43012) with TFT Display Shield Board (CY8CKIT-028-TFT).

The following article explains all necessary steps to create an Embedded Wizard UI application suitable for the PSoC 62S2 Wi-Fi BT Pioneer Kit (CY8CKIT-062S2-43012) from Infineon/Cypress.

Please follow these instructions carefully and step by step in order to ensure that you will get everything up and running on your target. In case you are not familiar with Embedded Wizard, please read first the chapter basic concepts and the Quick Tour tutorial to understand the principles of Embedded Wizard and the GUI development workflow.

Since the PSoC 62S2 Wi-Fi BT Pioneer Kit (CY8CKIT-062S2-43012) does not contain a display onboard, it can be combined easily with an external display controller, like the ST7789V or others. These types of display controllers can be accessed very easy by using the SPI or parallel data interfaces and they contain their own display memory. As a result, the entire framebuffer can be located inside the display controller and only a small scratch-pad buffer is needed inside the micro-controller (MCU). For this purpose, Embedded Wizard supports a partial display update, that makes it possible to update the display in sequential small areas. This makes it possible to operate with a scratch-pad buffer of a few kilobytes instead of a full-screen framebuffer within the memory space of the MCU.

Please note: The partial display update is intended to be used for extremely memory-constrained systems. Due to the fact that the display update is done in subsequent updates of small areas, moving graphical objects can cause some tearing effects. The UI design should consider this aspect.

Although you can combine the PSoC 62S2 Wi-Fi BT Pioneer Kit (CY8CKIT-062S2-43012) with many different display controllers or your own hardware, we highly recommend to start first with the following hardware components in order to ensure that you get the entire software up and running.

First, make sure you have all of the following items:

The provided Embedded Wizard Build Environment for PSoC 62S2 Wi-Fi BT Pioneer Kit contains everything you need to create, compile, link and flash an Embedded Wizard UI application for the PSoC 62S2 Wi-Fi BT Pioneer Kit in combination with the TFT Display Shield Board (CY8CKIT-028-TFT). After unpacking, you will find the following subdirectories and files:

For the first bring up of your system, we recommend to use the example 'HelloWorld':

Example 'HelloWorld' within Embedded Wizard Studio.

The following steps are necessary to generate the source code of this sample application:

The following steps are necessary to build and flash the Embedded Wizard UI sample application using the ModusToolbox toolchain:

The subdirectory \Application\Project\ModusToolbox contains a template project that is commonly used for all provided Embedded Wizard examples. All Embedded Wizard examples will store the generated code within the common /Application/GeneratedCode folder.

The given ModusToolbox example under \Application\ ModusToolbox contains a workspace which has all adaptions for an Embedded Wizard project. For using this within Infineon/Cypress ModusToolbox IDE do following steps:

If everything works as expected, the application should be built and flashed to the PSoC6 target.

Example 'HelloWorld' running on PSoC 62S2 Wi-Fi BT Pioneer Kit (CY8CKIT-062S2-43012).

All other examples can be created in the same way: Just open the desired example with Embedded Wizard Studio, generate code and rebuild the whole application using the above steps.

In order to create your own UI project suitable for the PSoC6 target, you can create a new project and select the PSoC 62S2 Wi-Fi BT Pioneer Kit project template:

As a result you get a new Embedded Wizard project, that contains the necessary Profile attributes suitable for the PSoC 62S2 Wi-Fi BT Pioneer Kit (CY8CKIT-062S2-43012):

The following profile settings are important for your target:

Now you can use the template project in the same manner as it was used for the provided examples to compile, link and flash the binary.

After generating code, build and download the application using ModusToolbox IDE as described above.

Most of the project settings are taken directly out of the generated code, like the color format or the screen orientation. All other settings can be made directly within the file ewconfig.h, which contains general configuration settings for the target system.

In order to receive error messages or to display simple debug or trace messages from your Embedded Wizard UI application, a serial terminal like 'Putty' or 'TeraTerm' should be used.

This terminal connection can be used for all trace statements from your Embedded Wizard UI applications or for all debug messages from your C code.

The layout of the interface between the PSoC 62S2 Wi-Fi BT Pioneer Kit (CY8CKIT-062S2-43012) and the TFT Display Shield Board (CY8CKIT-028-TFT) can be optimized so that the data lines are not scattered over several GPIO registers. By doing this modification, the performance of the display update can be increased significantly. Instead of setting each GPIO pin individually, the entire GPIO register is set at once.

The following table shows the list of changed connections between the PSoC 62S2 Wi-Fi BT Pioneer Kit (CY8CKIT-062S2-43012) and the TFT Display Shield Board (CY8CKIT-028-TFT):

Display Pin	Original	Optimized
DB11	J2, A12	J2, A11
DB12	J2, A13	J2, A12
DB13	J2, D7	J2, A13
DB14	J2, D8	J2, A14
DB15	J2, D9	J2, A15

After doing the hardware modifications, please set the define EW_USE_OPTIMIZED_LCD_PINNING within the file ewconfig.h to 1 and rebuild the application.
