  • XA-S3的IIC接口的驱动器软件程序(C语言)

    The XA-S3 is a member of Philips Semiconductors’ XA (eXtended Architecture) family of high performance 16-bit single-chip Microcontrollers. The XA-S3 combines many powerful peripherals on one chip. Therefore, it is suited for general multipurpose high performance embedded control functions.One of the on-chip peripherals is the I2C bus interface. This report describes worked-out driver software (written in C) to program / use the I2C interface of the XA-S3. The driver software, together with a demo program and interface software routines offer the user a quick start in writing a complete I2C - XAS3 system application.

  • 实验指导书 (TPC-H实验台C语言版)

    《现代微机原理与接口技术》实验指导书 TPC-H实验台C语言版 1.实验台结构1)I / O 地址译码电路如上图1所示地址空间280H~2BFH共分8条译码输出线:Y0~Y7 其地址分别是280H~287H、288H~28FH、290H~297H、298H~29FH、2A0H~2A7H、2A8H~2AFH、2B0H~2B7H、2B8H~2BFH,8根译码输出线在实验台I/O地址处分别由自锁紧插孔引出供实验选用(见图2)。 2) 总线插孔采用“自锁紧”插座在标有“总线”区引出数据总线D7~D0;地址总线A9~A0,读、写信号IOR、IOW;中断请求信号IRQ ;DMA请求信号DRQ1;DMA响应信号DACK1 及AEN信号,供学生搭试各种接口实验电路使用。3) 时钟电路如图-3所示可以输出1MHZ 2MHZ两种信号供A/D转换器定时器/计数器串行接口实验使用。图34) 逻辑电平开关电路如图-4所示实验台右下方设有8个开关K7~K0,开关拨到“1”位置时开关断开,输出高电平。向下打到“0”位置时开关接通,输出低电平。电路中串接了保护电阻使接口电路不直接同+5V 、GND相连,可有效地防止因误操作误编程损坏集成电路现象。图 4 图 55) L E D 显示电路如图-5所示实验台上设有8个发光二极管及相关驱动电路(输入端L7~L0),当输入信号为“1” 时发光,为“0”时灭6) 七段数码管显示电路如图-6所示实验台上设有两个共阴极七段数码管及驱动电路,段码为同相驱动器,位码为反相驱动器。从段码与位码的驱动器输入端(段码输入端a、b、c、d、e、f、g、dp,位码输入端s1、 s2)输入不同的代码即可显示不同数字或符号。

  • 汇编语言和C语言的外部中断

    CPU在处理某一事件时,发生了另一事件请求CPU迅速去处理。CPU暂时中断当前的工作,转去处理事件B。待CPU将事件B处理完毕后,再回到原来事件A被中断的地方继续处理事件A。这一处理过程称为中断。介绍用汇编和C语言两语言的源程序,愿给大家带来帮助。 前面我已经上传了几个程序,没几天却失踪了。但这次的不会失踪,能保留上几天。
