飞利浦RC522芯片源代码。该芯片主要针对三表市场和手持设备，支持I2C/SPI/UART接口。 先发布基于普通51单片机的驱动源代码，采用串口接口，无需中断。只要接一个串口，后续会发布基于飞利浦LPC9401的读写源代码！LPC9401也是基于51核，只需连接SPI接口！有公司拿这个源代码卖钱哟-Philips RC522 chip source. The chip targeted at three tables and handheld devices market, support I2C/SPI/UART interface. Based on the first general release 51 MCU-driven source code, using serial interface, without interruption. As long as a serial port access, the follow-up will be issued based on the Philips LPC9401 write source code! LPC9401 is based on the 51 nuclear, only connecting SPI interface! A company with the source code acquisition yo! !
