| Abstract: | Based on the needs of balise and the design concepts of embedded system,this paper proposes a new method of portable wireless programming.In this method,hardware design is completed by using FPGA&ARM.Specifically,the modulation and demodulation unit and the central control unit respectively adopt the principle of FPGA and ARM.Meanwhile,software design achieves the requirements of real-time,security and efficiency by useing μC/OS-Ⅱ technology which is a real-time and multi-task design.In addition,it uses RS-232 and Bluetooth communication mode to facilitate program operation and data transmission.Moreover,the adoption of LCD display and keyboard shows a good effect of human-computer interaction.Finally,the output waveforms observed through the oscilloscope meet the design requirements. |
