文件格式 2001年春季的IDF上Intel正式公布PCI Express
2001年春季的IDF上Intel正式公布PCI Express，是取代PCI总线的第三代I\O技术，也称为3GIO。该总线的规范由Intel支持的AWG（Arapahoe Working Group）负责制定。2002 年4月17日，AWG正式宣布3GIO 1.0规范草稿制定完毕，并移交PCI-SIG进行审核。开始的时候大家都以为它会被命名为Serial PCI（受到串行ATA的影响），但最后却被 ...
书籍 Autonomous+Robots+Modeling,+Path+Planning
A kinematically redundant manipulator is a serial robotic arm that has more
independently driven joints than are necessary to define the desired pose (position
and orientation) of its end-effector. With this definition, any planar manipulator (a
manipulator whose end-effector motion is restrained in ...
技术资料 STM32F407、STM32F405系列芯片手册
SPI 是英语 Serial Peripheral interface 的缩写，顾名思义就是串行外围设备接口。是 Motorola首先在其 MC68HCXX 系列处理器上定义的。 SPI 接口主要应用在 EEPROM， FLASH，实时时钟， AD 转换器，还有数字信号处理器和数字信号解码器之间。 SPI，是一种高速的，全双工，同步的通信总线，并且在芯片的管脚上只占用四根线， ...
