Dalian Da Youshang Group launched a code table solution based on ST STM32 Cortex-M4 (STM32F4 or L4)

The leading distributor of semiconductor components dedicated to the Asia-Pacific market, Grand United Holdings, announced that its subsidiary Youshang has launched a code table solution based on STMicroelectronics (ST) STM32 Cortex-M4 (STM32F4 or L4).

On April 20, 2021, the leading distributor of semiconductor components dedicated to the Asia-Pacific market-Grand United Holdings announced that its subsidiary Youshang has launched a code table based on STMicroelectronics (ST) STM32 Cortex-M4 (STM32F4 or L4) plan.

The simplest way to implement a graphical interface on a microcontroller system is to use a serial port screen. However, in a limited handheld application, the size and adaptability of the serial port screen Display often cannot meet the needs, which requires the use of a GUI framework to complete the graphical interface . In the field of microcontrollers, TouchGFX is an advanced free graphics software framework optimized for STM32 microcontrollers.

Utilizing the graphics functions and architecture of STM32, TouchGFX accelerates the revolutionary process of man-machine interface by creating stunning smartphone-like graphical user interfaces. The TouchGFX framework includes TouchGFX Designer, an easy-to-use PC tool based on drag-and-drop prototyping, and a powerful graphics core TouchGFX engine. TouchGFX combines a WYSIWYG simulator and automatic code generation to make GUI development easier.

Related tools introduction:

TouchGFX Designer is an independent software tool that allows simple and fast graphical evaluation and proof of concept. It is fully compatible with STM32CubeMX initialization and code generation tools, and can seamlessly develop graphics and main applications in a unified project environment.

STM32CuBeIDE is an advanced C/C++ development platform with the peripheral configuration, code generation, code compilation and debugging functions of STM32 microcontrollers and microprocessors. It is based on Eclipse® /CDT framework and GCC tool chain for development, GDB for debugging. It allows integration of hundreds of existing plug-ins, which complete Eclipse® Function of IDE.

STM32CubeProgrammer is a multi-operating system software tool for programming STM32 products. It provides an easy-to-use and efficient environment for reading, writing, and verifying device memory through the debug interface (JTAG and SWD) bootloader interface (UART, USB DFU, I²C, SPI, and CAN).

STM32CubeMX is a graphical tool that allows very simple configuration of STM32 microcontrollers and microprocessors, and can also be used for Arm through a step-by-step process® Cortex® -M core or Arm® Cortex® -a core generates part of Linux® Device tree.
