单片机开发 This code implements the basic functions for an I2C slave device using the SSP module. All I2C funct

This code implements the basic functions for an I2C slave device using the SSP module. All I2C functions are handled in an ISR. Bytes written to the slave are stored in a buffer. After a number of bytes have been written, the master device can then read the bytes back from the buffer.

SQL Server 一般我们要根据数据库的纪录变化时

一般我们要根据数据库的纪录变化时，进行某种操作。我们习惯的操作方式是在程序中不停的查询表，判断是否有新纪录。这样耗费的资源就很高，如何提高这种效率，我想在表中创建触发器，在触发器中调用外部动态连接库通过消息或事件通知应用程序就可实现。而master的存储过程中最好能调用外部的动态连接库，我们在触发器中调用 ...

微处理器开发 12Mhz标准51的100KHz IIC总线主器件模拟方式驱动程序。 本驱动程序即可以在没有Small RTOS的情况下使用。此时

12Mhz标准51的100KHz IIC总线主器件模拟方式驱动程序。 本驱动程序即可以在没有Small RTOS的情况下使用。此时，要使用本驱动程序只需要配置IIC总线使用的IO口。在驱动程序的主文件iic_master.c仅包含一个文件config.h。用户需要的是在这个文件中设置IIC总线使用的IO口SDA和SCL。如果用户单独使用iic_master.c，还要在confi ...

单片机编程 PCA954X家庭的I C SMBus多路复用器与开关

The Philips family of Multiplexers and Switches consists of bi-directional translating switches controlled via the I2C or SMBus to fan out an upstream SCL/SDA pair to 2, 4 or 8 downstream channels of SCx/SDx pairs. The Multiplexers allow only one downstream channel to be selected at a time, while th ...
