stm8

在进行STM8 软件编写时,请着重注意以下要点: 1. 时钟分配 主时钟是否正常起振并稳定,各个外设时钟是否开启 2. 选项字节配置(option bytes) A. I/O重映射功能状态是否与实际项目相符合 B. 如果看门狗使用硬件方法使能,则看门狗在复位后立即有效,主程序必须喂狗。 C. 若果MCU主频高于16MHz,则需要配置选项字节的MCU等待周期为1

μC_OS-Ⅱ操作系统在DSP5402上的FAR模式移植

·摘要:  μC/OS-Ⅱ操作系统作为一种简单高效的RTOS,它的应用范围很广,并有移植到各种处理器上的范例,如DSP在NEAR模式下的移植.文中介绍了该操作系统在5402DSP的FAR模式下的移植,首先描述FAR模式与NEAR模式的区别,然后结合源代码对μC/OS-Ⅱ操作系统在该模式下的移植的具体步骤进行了详细分析.

CDMA通信系统中盲多用户检测算法

多用户检测是第三代移动通信的关键技术之一。传统的检测方式是把多址干扰(MAI)当作噪声来处理,不能充分的利用多用户的信息,从而降低了通信质量和系统容量;而多用户检测是把多址干扰作为有效信息来处理,并能有效地克服远近效应(Near-Far Effect),提高系统容量。然而频繁的发送训练序列严重制约了多用户检测技术的实时性和实用性;由于盲多用户检测只需利用期望用户的信息就可以进行检测,它有着更加广阔
