| 摘 要： | 针对SPI总线接口缺乏标准协议的特点，提出了SPI器件之间通信的一般方法。论文阐述了ARM芯片内置SPI硬件控制器的工作原理和时序，并对射频芯片TRF7960x的工作模式与读写要求进行了分析。在此基础上，根据TRF796x的时序特性和访问要求，采用ARM芯片的硬件SPI方式实现对TRF796x的读写访问与控制，并在RFID门禁系统中验证了通信结果。

| Abstract: | Because of SPI-bus interface's lack of standard protocol,a general communication method between SPI-devices is introduced.The paper expounds the working principle and timing of SPI controller built-in ARM,and analyzes the working mode and access requirements of RF chip TRF796x.Base on this and according to the timing characteristic and access requirements of TRF796x,ARM hardware-circuit SPI mode is used to implement the access and control of TRF796x,and the communication effect is verified in RFID entrance ... |
