WL0F00039000QGAAASA00 is a 3.9" Smart Display CAN series TFT 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. WL0F00039000QGAAASA00 is integrated with a standard 3.9 inch Bar TFT module WF39QTIBSDBG0 and 4-layers PCBA with built-in firmware code which is developed by WINSTAR. This 3.9" Smart Display CAN series TFT is an easy-to-use product which allows customers to develop projects rapidly in cost-effective way. This 3.9” 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).

WINSTAR Smart Display CAN Series is really a "smart" choice for customers. There are many important features and functions for the new released 3.9" smart display CAN TFT as below:

• DC 5V working voltage, low power consumption for USB to drive.
• Self testing after booting function.
• CAN bus communication interface.
• Support CANopen negotiation. Default baud rate is 250Kbps.
• Built in flash memory, store the font and Object Dictionary Data.
• Support capacitive touch panel (CTP).
• Smart Display scenario is slave device display and action from Master Device instruction.
• Embedded buzzer controlled by Master Device.
• HOST can be used on multiple platforms, such as Computer (with USB to CAN Dongle), MCU, Raspberry Pi (with PiCAN2).
• Design the UI without writing a line of code by WINSTARGUI builder! (►Link to GUI Builder Introduction)
• Designed with STM32F series MCU and Support STMicroelectronics' (ST) software development tools.
