The design of wireless air mouse based on LPC54100
With the development of the times, the traditional flat-type mouse can not meet the mobile office and entertainment on the three-dimensional space control requirements. In this context, wireless squirrels do not need any plane. In the air, gently swing the mouse can achieve large-screen control, so it has a good market prospects. In this paper, after knowing the wireless flying mouse needs to achieve the requirements of air control, wireless transmission and low power consumption, we have carried out the design of wireless flying mouse. First, according to the characteristics of low power consumption, the main part of the wireless flying mouse is chosen as below. LPC54100 Series MCU is chosen as the main controller. The motion sensor module called MPU6050 is used to receive the hand control information. Two Bluetooth supporting low-power are used as communication module. The reduced click jitter capacitance touch key module is added. Then the Altium Designer is used to design the hardware circuit and the PCB circuit board divided into two parts of the mouse and the receiving end. The program is wrote to achieve the function of controlling the computer cursor, clicking the left and right key of the mouse, low power sleep mode and Bluetooth communication. Finally the actual use effect is tested and some adjustments is made on the basis of the test.
