With the continuous improvement ofthe function ofthe microprocessor, the application ofembedded operating system es more and more powerful. The research ofsoftware design based onspecific embedded operating system has e ahot spot inrecent years, and ithas important significance for the application ofembedded operating system inpractical engineering. Inthis paper, the use ofdandelion STM32F103 development board, the use ofKeil software tocreate the project. Transplant UCOS system kernel, the application ofClanguage program. Complete the construction offour tasks and scheduling: LED lights, buttons, LCD display screen, MPU6050 acceleration sensor data acquisition, change the LED lamp through the button display, through real-time acquisition ofMUP6050 sensor data, display onthe LCD, and the task of transmission ofinformation between signal and message mailbox.
