ABSTRACT
Embedded system is developing forward to humanization at present. A friendly, simple, easy graphical user interface has become an important part of many embedded systems. In the past, the design of graphical interfaces cost a lot of time and energy, and that conditioned the product as soon as possible to themarket.To solve this problem, many semiconductor manufacturers now not only sell a new processor, but also launch processor supporting software at the same time. ST launched the MCU for the STM32 series which is based on an ARM Cortex-M3 core. It comes with the peripheral base,motor driver library, standard protocol stack, and STemWin graphics driver. All developers need to do, is to modify the basic hardware driver interface program. Then the STemWin graphics driver library can run on the MCU of the STM32 series.
