Delphi控件源码 本程序是在网友vagrant的升级程序上增加了SQL数据库的更新升级功能
本程序是在网友vagrant的升级程序上增加了SQL数据库的更新升级功能,系统中采用了ACCES来存储数据更新的指令,从而达到逐步执行SQL代码的功能,因为在SQL中要创建表、存储过程、视图等对象时,需要删除原有老的对象,但是SQL不支持将这些指令存放在一起,从而导致出错。所以用ACCES来存储数据了
例中将在MASTER中创建p_kil ...

VHDL实现SPI功能源代码
-- The SPI bus is a 3 wire bus that in effect links a serial shift
-- register between the "master" and the "slave". Typically both the
-- master and slave have an 8 bit shift register so the combined
