MDK开发环境从V4升级到V5后,支持包不再是集成到开发环境当中,而是封装在PACK中,需要自行安装,比较麻烦. 搭建MDK开发环境以及破解的方法,在前面的文章中有详细说明,这里不再赘述,有兴趣的可以参考:http://www.cnblogs.com/huanzxj/p/6200928.html 搭建好开发环境,在编译完代码需要下载的时候,需要选择下载算法:add flash programming algorithm,这时候可能会遇到本文锁讲述的问题,找不到与你使用的MCU 对应资源的软件算法…
注明来自 http://www.ssdfans.com/?p=5589 以MLC为例: 对FGF(Floating Gate Flash)技术的,MLC programming一般分两步走:先program Lower page,然后program Upper Page. 对某个Cell来说,当写入1时,无需Programming,阈值电压保持不变,还是处于E状态:当写入0时,必须进行Programming,使它的阈值电压落到D范围 ,即E->D. Programming某个page时,往其所在…
With our Redux implementation lousy with State ADT based reducers, it is time to hook it all up to a React Shell. Having already built out some UI/UX in React that is connected to our store, we’ll spend the first part of this lesson with a quick tour…
The typical Redux Reducer is function that takes in the previous state and an action and uses a switch case to determine how to transition the provided State. We can take advantage of the Action Names being Strings and replace the typical switch case…
Being able to display values for counters, sensors and other debugging information is an important part of software development for microcontrollers.  Writing software for PCs is much easier in this regard as there is already a monitor to which you c…

1 Debug Interface Overview 1.1 Serial Wire Debug Serial Wire Debug (SWD) is a two-wire protocol for accessing the ARM debug interface. It is part of the ARM Debug Interface Specification v5 and is an alternative to JTAG. The physical layer of SWD con…
JTAG Finder Figuring out the JTAG Pinouts on a Device is usually the most time-consuming and frustrating process and Finding the pinouts for these ports allows you to access with correct JTAG Devices likeGPG ORT,  and JTAG Finder helps you to get sta…
Serial Wire Debug (SWD) provides a debug port for severely pin limited packages, often the case for small package microcontrollers but also complex ASICs where limiting pin-count is critical and can be the controlling factor in device costs. SWD repl…
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…
AVR Programming Methods  There are many ways to program AVR microcontrollers. Since many people ask about different ones at one time or another, I thought I'd outline them here so that their questions can be answered quickly and efficiently. Please f…
Error:Flash Download Failed-"Cortex-M3"出现一般有两种情况: 1.SWD模式下,Debug菜单中,Reset菜单选项(Autodetect/HWreset/sysresetReq/Vectreset)默认是AutoDetect,改成SysResetReq即可. 2.Jtag模式下,主要是芯片大小选错.Flash->Configure Falsh Tools配置窗口,切换到“Utilities"页,按“Setting"按钮进…

用户在调试内嵌可综合内核的 CPU 如 ARM7TDMI-S 时,需要通过打开仿真器的自适应时钟功能. 此时,ARM仿真器根据 RTCK 时钟信号的频率,产生可用于 CPU 内核当前时钟主频的最快的 TCK 时钟. 即 ARM 内核的时钟主频变化,引起 RTCK 变化, 仿真器根据 RTCK 的变化,产生合适的最快的 TCK 时钟. 如果没有有效的 RTCK 信号,用户不能使用自适应时钟功能.这种情况下,用户可以设置 TCK 为比较低的频率. 当用户确认 CPU 运行在比较高的频率的情况下,可以…
JTAG Simplified So the other day, I explored the JTAG bus interface which is frequently found in CPLDs/FPGAs and is most of the times the sole method of programming and debugging them. It is a powerful interface and very easy to use. I intend to writ…

NOR Flash擦写和原理分析 1. NOR FLASH 的简单介绍 NOR FLASH 是很常见的一种存储芯片,数据掉电不会丢失.NOR FLASH支持Execute On Chip,即程序可以直接在FLASH片内执行(这意味着存储在NOR FLASH上的程序不需要复制到RAM就可以直接运行).这点和NAND FLASH不一样.因此,在嵌入式系统中,NOR FLASH很适合作为启动程序的存储介质.NOR FLASH的读取和RAM很类似(只要能够提供数据的地址,数据总线就能够正确的给出数据),…
