Description
WL0F0007000A8GAAASA00 is a 7" 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. WL0F0007000A8GAAASA00 is integrated with a standard TFT module WF70A8TYAHLNG0 and 4-layers PCBA with built-in firmware. This 7" Smart Display _CAN series TFT is an easy-to-use product which allows customers to develop projects rapidly in cost-effective way. This 7” Smart Display can use computer with USB2CAN dongle or Raspberry Pi interface (PiCAN2) as HOST platform.
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

Display Usage
Functional description
Smart Display can be used to display the coordinate, status and data information provided by the connected HOST device. Customers can configure the position coordinates they want to display in normal operation mode.The Display is designed to be easily connected to a controller network, and to operate with minimum setup or knowledge of the SDO configuration on the controllers.
Splash Screen
The default splash image is shown below.
Default Selection
Press the preferred application and hold for 3 seconds for the first time power on.
Acquisition of Displayed Data
The Smart Display can acquire the data that it displays either using the CANopen SDO protocol, or using the CANopen PDO protocol.On Pre-operational mode, customers can set the coordinates of objects through SDO; On operational mode, customers can send data of objects through PDO.
Configuring the Display
Winstar Smart Display CAN series offers an out-of-the-box CANopen development experience that will lower customers' development costs and speed time-to-market expectations.The Smart Display can use wide-temperature are designed to support control applications in harsh operating conditions, which designed to be connected to a variety of different situation combinations, such as automotive, marine, power generation and oil-and-gas. The Smart Display comes with standard UI objects to get customers project off the ground quickly. If customers need custom UI objects support, our engineers are here to help. Send over your contents in PNG/JPG format, we will send over a new set of UI objects within 3~5 working days.
The Smart Display is defined as a slave device, which 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.
