Nrf24e1 Chip Universal Remote Prototype Design

The birth of wireless SoC MCU provides short-range wireless communication with simple solution scheme. It is ideal scheme of developing low-cost and low-power wireless communication systems. And nRF24E1 is just the one of excellent wireless SoC MCUs.In this paper, nRF24E1 is first introduced briefly. Based on this presentation, the system scheme of universal remote transmitter and receiver is put forward, the design of every part of hardware circiut and the software program flows are detailedly described. Fanally the debugging methods and the results of the hardware, software and system are presented.On this remote controller, MCU controls LCD to display related information and transfers data according to the commands inputted through the keyboard. It can overcome drawbacks of remote controllers on the market and control many kinds of electrical appliances. So the idea of applying the universal remote controller is proved feasible.
