WL0F00043000WGAAASA00 model is a 4.3" Smart Display CAN series TFT display which is defined as a slave device, that is controlled by master device via CAN bus command to render display content on the display screen and return touch event data with protocol objects. WL0F00043000WGAAASA00 model is integrated with a standard 4.3 inch IPS TFT module WF43WTWAEDNGA and a 4-layers PCBA with built-in firmware code which is developed by WINSTAR RD team. This 4.3" Smart Display CAN series TFT is an easy-to-use product which allows customers to develop projects rapidly in cost-effective way. This 4.3” Smart Display can use computer with USB2CAN dongle or Raspberry Pi interface (PiCAN2) as HOST platform. WINSTAR already developed a Windows IDE for Smart Display GUI design. WINSTAR GUI builder software is designed for customers to simulate their GUI design in advance by using the drag-and-drop Widget preview function; furthermore, customers can create their ideal GUI by themselves by using this software. WINSTAR GUI builder software is supporting Windows system only; it can fulfill What You See Is What You Get (WYSIWYG).

Smart Display products are designed with STMicroelectronics' (ST) controller which supports ST development tools like TouchGFX and STM32CubeIDE. You can also use ST tools to design WINSTAR Smart Display modules besides GUI builder.

  • TouchGFX: An advanced free-of-charge graphic software framework optimized for STM32 microcontrollers.
  • STM32CubeIDE: An advanced C/C++ development platform with peripheral configuration, code generation, code compilation, and debug features for STM32 microcontrollers and microprocessors.
  • STM32CubeMX: A graphical tool that allows a very easy configuration of STM32 microcontrollers, as well as the generation of the corresponding initialization C code for the Arm® Cortex®-M core or a partial Linux® Device Tree for Arm® Cortex®-A core, through a step-by-step process.
  • STM32CubeProg: An all-in-one multi-OS software tool for programming STM32 products. It provides an easy-to-use and efficient environment for reading, writing and verifying device memory through both the debug interface (JTAG and SWD) and the bootloader interface (UART, USB DFU, I2C, SPI, and CAN).

We’ve also pushed the sample code on Github for your ST platform design reference: ► Link to Github
