| Abstract: | Based on a wireless computer remote control, designed a wireless remote control system with voice transmission and table data transmission using NRF24E1. According to the different characteristics of press data、speech data and the table data,the data were multiplexed,developed a data transfer protocol. To ensure that the data real-time transmission,ISM band used to transmit data. Frequency division multiplexing used in different systems, Which can achieve interference free transmission in many systems. The system design, the hardware schematic diagram and the software flow were given out, and the function of the system was tested. Studies show that the system can realize intelligent wireless keyboard, wireless tablet and wireless voice function. |
