LPC1800 Series microcontrollers At 180 MHz, LPC1800 Series microcontrollers combine the industry's fastest ARM Cortex-M3 core with multiple high-speed connectivity options, advanced timers, analog, and optional security features to secure code and da…

MCU的启动方式有很多种:UART接口,扩展的静态存储单元(NOR Flash), SPI Flash,quad SPI Flash,高速USB0和USB1.另外可以通过对OTP存储单元的编程. 首先看下内存映射: 在MCU复位之后,ARM处理器将会从ROM区域执行代码. LPC43XX包含一个隐藏指针允许内存区域映射到地址0x00000000. 隐藏指针的默认值为0x1040 0000,保证了启动ROM中的代码在复位的时候被执行. 如果启动方式从flash区域开始,那么系统默认会从内部flas…

jtagger Versatile multiprogrammer for FPGAs, MCUs, etc. Well, it's not really just a jtagger, but I've been calling it that. It's also been christened the Bit Quacker... uh, because it quacks? *shrug* The basis for this design is sort of like the Bus…

当你打开网站时,点击该软件下载会发现如下页面: google一下会出现这个界面,大意是这个版本的编译器太老了,已经被某些更加高级的编译器给取代了(qaq心痛) 然后我就开始FQ到处google,SourceForge.github等上面开始找资源--(此处省略三四十个字) 过程比较艰辛,搞了还几天,大多数事件浪费在了看各种英语网站上了 下面挂两个网站资源(第二个国外网站) http://www.infortech.net.cn/index.php?c=msg&id=206& http://…

What is the difference between a Bootrom vs bootloader on ARM systems Bootrom Bootrom (or Boot ROM) is a small piece of mask ROM or write-protected flash embedded inside the processor chip. It contains the very first code which is executed by the pro…
