中断串口程序-interruption procedures

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! !

日历时钟DS12887控制实验 实验步骤 （1）连CZ1→CZ7，/IRQ(MC3)→P3.2。 （2）运行程序CLOCK.ASM，主机提示"SE――"等待键输入，①如按F0/EX，则读取显示当前已设置的日历钟。②如按数字键、再按SCAL键，则重新设置日历，例如设置日历为2002年02月22日，只需输入02 02 22即可，20为固定设置，不需输入。-Calendar Clock DS12887 control experiment experimental steps (1) even CZ1 → CZ7,/IRQ (MC3) → P3.2. (2) run the program CLOCK.ASM, host prompt

利用FPGA的资源实现任意波形的产生，再若和单片机配合就能做成任意的波形发生器。-Use of FPGA resources for the realization of arbitrary waveform generation, again if and SCM can be made with the arbitrary waveform generator.
