是关于集成运算放大器应用电路集,我找了很久的东西,里面非常的全面,特地拿出来共享,我想对硬件工程师来说没有人会不喜欢这个东东吧~用超星打开-on Integrated Operational Amplifiers circuit sets, I find things for a long time, there is very comprehensive, specifically up sharing, I would like to hardware engineers who would not like it to the Eastern opened with Superstar

该工具为嵌入式交叉编译工具，适用于Linux平台，具备Debug功能及反汇编等，是一款嵌入式Linux开发必不可少的工具。

1， SPI_877A,是针对PROBE877A所写。 SPI_877,是针对PROBE877所写。 SPI_77，是针对PROBE77所写。 初次使用使用PICMATE2004或者其简化版精灵版，如果为以上提到的3款型号，并有TPDEM1， 请根据PROBE型号在相应文件夹下打开项目，编译，并运行，具体连线请看各文件夹说明。 2， 其它文件夹项目均针对PROBE877A所建立，如果要使用PROBE877，请修改头文件，并选择PROBE877支持的芯片。 3， 严格禁止将PROBE877与877A混用，否则将造成仿真芯片工作异常。-1, SPI_877A, is written by PROBE877A. SPI_877, is written by PROBE877. SPI_77, is written by PROBE77. First-time use or its PICMATE2004 Wizard version of Starter Edition, if for the above-mentioned models 3 and TPDEM1, please PROBE models in the corresponding folder to open the project, compile, and run, the specific connection see the folder Note. 2, other projects are folders created for PROBE877A, if you want to use PROBE877, please amend the header file, and select PROBE877 support chips. 3, is strictly prohibited PROBE877 and 877A will be a mix, or else the work will result in simulation chips abnormal.

基于ARM7TDMI的uClinux移植,44b0x-uClinux transplantation, 44b0x

本工程是基于飞思卡尔（freescale）的k20单片机，通过将uc_osIII移植到K20单片机上，本程序实现了创建一个串口通信任务，使用UART实现单片机和PC的通信，需要的童鞋可以很容易进行修改，移植到自己的单片机上。
