Description: 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! !

Description: 用单片机的I/O口模拟I2C协议
I2C用IO模拟程序网上范例最多的就是51的程序了,这些范例的正确性无需怀疑.但是如果直接以它为蓝本将它"AVR化",一不留神,就会有点问题了.
这要从I2C的硬件规范和AVR及51单片机的IO口说起.I2C要求SCL,SDA二线都有 线与 功能,即I2C驱动口应该是 漏极开路 电路,其高电平的维持是靠上拉电阻来实现的, 而低电平则需要驱动口的强下拉能力.
51单片机IO口正好完全符合这个特性.写起I2C驱动颇为得心应手.但是AVR的IO口强大了,它输出的高电平是实实在在的高电平,而不是靠什么上拉电阻来提供,只有10mA都不到的电流!于是如果直接使用 PORTB_Bit0 = 1这样的操作,就不能满足I2C的线与功能了,如果此时有别的设备要将SCL或者SDA拉低,那么结果就是二个IO口打架,谁赢谁输不得而知,时间长了,多半是两败俱伤,芯片发热吧.
当然AVR的IO口自然有办法满足I2C的电气特性要求,不就是不能输出1么,那么用它的高阻状态即可(DDRB_Bit0=0,PORTB_Bit0=0即可),要输出0么(DDRB_Bit0=1,PORTB_Bit0=0).
