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! !

P89V51RD2系列芯片是具有串口下载功能（ISP）和在KEIL中进行调试的功能（SOFTICE）。 新的芯片是ISP功能，通过FlashMagic 软件可以设置其为SOFTICE功能。 但要想回到ISP功能，则没有现成的好办法，只有通过编程器了。 但现在可以通过这个程序来恢复其ISP功能（禁止SOFTICE）。-P89V51RD2 series with the serial port chip is the ability to download (ISP) and the KEIL for debugging feature (SOFTICE). The new chip is the ISP, through FlashMagic software can be set to SOFTICE its function. However, to return to the ISP, there is no ready-made good, and that only through a programmer. But now through this procedure to restore its ISP (Prohibition SOFTICE).
