Abstract
To solve the effect that the multi threading task can be achieved by the TFT of color screen, we adopt MSP430F5438 as the main controller, the main equipment of its hardware system was built by the TFT of touch screen, and the task driving function was completed by using buttons and wireless communication module and other peripherals. And we have developed the application program based on UC/OS operating system utility with the kernel structure and characteristics of UC/OS. It can be realized these function, such as digital tube display, TFT display task, multi-tasking, wireless communication, the task driving system, touch screen and low power verification task. The experimental results show that it completely meets the desired design goals, it works reliable and stable.
