[Embeded-SCM Develop] SMBUS

Description: C8051F020 / 040 等等单片机内部SMBUS总线驱动程序源代码(原创) 使用Keil C51编译环境 程序中没有使用SMBUS中断方式,使用查询中断方式运行,这样程序结构简单,便于扩展其他SMBUS设备. 本程序中带IIC器件驱动,可支持24C01 - 24C512(128字节 - 64K字节)非易失性存储器.只需要先初始化SMBUS,再初始化24Cxx器件的时候给出24Cxx的器件地址/内部地址宽度和器件写分页大小即可. 其中还带IIC总线的RFID射频卡HY502的基本驱动程序. 上述2种器件的驱动可由.H头文件配置启用或禁止. 如需要HY502或有使用中的问题请联系我(Ynking):ynpsps@sina.com-C8051F020/040 and so on Singlechip SMbus internal bus driver source code (original) The use of environmental procedures Keil C51 compiler does not use SMbus interrupt, use the query interrupted run, this program structure is simple, easy to expand to other SMbus equipment. This proceedings with IIC device driver that supports the 24C01- 24C512 (128 byte- 64K bytes) non-volatile memory. just have to initialize the SMBUS, re-initialize the device when 24Cxx given 24Cxx device address/internal address width and the device can write page size. which IIC bus with RFID basic HY502 RF card driver. the above-mentioned two kinds of device drivers may be.

[SCM] C51

Description: 由8051组成的单片机系统通常情况下，P0口分时复用作为地址、数据总线，P2口提供A15-A8即高8位地址，P3口用作第二功能，只有P1口通常用作I/0口。P1口是8位准双向口，它的每一位都可独立地定义为输入或输出，因此既可作为8位的并行I/O口，也可作为8位的输入输出端。当工作在输入方式时，对应位的锁存器必须先置1,才能正确地读到引脚上的信号,否则,执行读引脚指令时,若对应位的锁存器的值为0，读的结果永远为0。-By 8051, composed of single-chip microcomputer system under normal circumstances, P0 timeshare I reuse as address, data bus, P2 I provide A15-A8 high eight address, P3 mouth for the second function, I usually only P1 for I/0 I. P1 I was eight quasi-two-way port, it can be independent of each and every defined as input or output, it can be used as 8-bit parallel I/O port, can also be used as 8-bit input and output side. When the work in the input, the corresponding bit latch must first buy one in order to correctly read the signal pin, or pin the implementation of reading instruction, if the corresponding bit latch the value of 0, Reading the results of Forever to 0.
