LPC43xx SGPIO Camera interface design

LPC43xx SGPIO Configuration The LPC43xx SGPIO peripheral is used to move samples between USB and the ADC/DAC chip (MAX5864). The SGPIO is a peripheral that has a bunch of 32-bit shift registers. These shift registers can be configured to act as a par

I²C SGPIO Configuration SGPIO is a hardware feature of LPC4300 series. There are 16 SGPIO pins called from SGPIO 0 to SGPIO 15. SGPIO is one of the functions of LPC 4300 pins which can be chosen. SGPIO could work as standard GPIO pins, or do stream p

The SGPIO output pins SGPIO14 and SGPIO15 can trigger a GPDMA request SGPIO pins SGPIO14 and SGPIO15 can trigger a GPDMA request. < Output = '1' > To generate the request, program a pulse in the bit stream of slice 14 or 15. For example, use a patte

User Stories Android UI Design 附加资源 User Stories: @.通过写故事来设计应用. @.每个故事只关注一件事. @.不同的故事可能使用相同的组件,因此尽早地对故事进行分类. @.把目标用户构想到故事里,描述他们的基本特征,会在什么时候.什么地点使用该应用等信息,因此来确定故事的优先级. Android UI Design: @.构思应用需要展示的界面及内容,不需要详细的界面设计. @.确定各界面的跳转关系. @.用户界面原型设计,可通过工具进行,比如A

模式匹配 所有位串均具有模式匹配功能. 该功能可用于检测启动代码等.要使用该功能,则必须用需匹配的模式来对REG_SS 编程 (请注意, POS 达到零时 REG_SS 不会与 REG  交换!) MATCH_MODE 位必须设为1. 输入数据 REG 现在与已编程的模式 REG_SS 相比较.发现匹配时会提出模式匹配中断. Bit MATCH_MODE selects whether the match filter is active or whether data is captured.

LPC4350 SGPIO Experimentation The NXP LPC43xx microcontrollers have an interesting, programmable serial peripheral called the SGPIO (Serial GPIO). It consists of a slew of counters and shift registers that can be configured to serialize and deseriali

http://ivomynttinen.com/blog/the-ios-7-design-cheat-sheet/ With the release of iOS 7, app designers and developers will need to adjust their visual language to match the new "flat" design of iOS. In addition to the grid system, the dimensions of

oop design 分为以下几个方面: - encapsulation and modularity(封装和模块化) - API/Client interface design(API 接口给调用类者) - Inheritance hierarchy and interfaces(继承和继承的层次关系) 这里先介绍一个modularity模块化: 一个大的系统是很复杂的, 可能包含了很多复杂的部分, 如果编码中的一个部分可以独立出来而被其他部分所使用, 例如之前的cs106中的画火车的例子,
