The new boards available from December (?) with Revision 0.6 + will have the OutputExpander Connector to communicate with the Shruthi Programmer. The pins goe 1:1 to the Programmers Connector, additionally you will have to connect CV1 to Pin 10.
Edsger Wybe Dijkstra 对，就是E.W. Dijkstra. 一提到EWD，很多人就会想起找最短路径的Dijkstra Algorithm，就好像一提到Sir. Tony Hoare，就想起Quick Sort一样。其实这些个算法不过是两个牛人在他们职业生涯中最琐碎的贡献。比如Dijkstra算法，无非是戴爷爷在1956年为了展示新计算机 ARMAC的计算能力，初试身手的成果，属于他的算法处女作。据戴爷爷自述，他搞出最短路径算法的时候连纸笔都没用。当时他和他老婆在阿姆斯特丹一家咖啡厅的阳台上晒太阳喝咖啡，突然就把这个算法想出来乐。而且当时的算法研究还比较原始，牛人们忙着用计算机搞数值计算，对离散算法不屑一顾。那时连一个象样的专注于离散算法的专业期刊都没有。戴爷爷于是推迟发表这个算法。直到1959年，他才把这个算法发表在Numerische Mathematik的创刊号上，权为捧场。:-) EWD在多个领域牛气冲天，端的是理论和编程两手硬的高手。只不过他的很多工作比较深刻，学校的老先生们觉得本科生接受不了，不给本科生讲而已。戴爷爷大概因为最短路径算法一战成名，于是有人请他参加另一台计算机X1的设计工作，并且把设计实时中断系统的任务派给了他。现在看来实时中断也许不算什么，但要知到，X1前根本就没有实时中断的概念。实现它简直就是一场豪赌。戴爷爷起初还不情愿，但经不住项目负责人Bram和Carel的轮番“吹捧”：我们知道实时中断让您工作变得非常困难，但象您这样的牛人肯定能做出来的说。结果戴爷爷被糖衣炮弹彻底击穿，接下了这个烫手山芋。两三年后，他不仅搞出了实时中断，还围绕这个写出了自己的博士论文，顺利戴上博士帽。让戴爷爷真正成名立万的还是在X1上开发的Algo60，最早的高级语言之一。戴爷爷没日没夜地工作了8个月，就搞出了Algo60，也因此获得了1972年的图灵奖。因为Algo60，戴爷爷发表了一篇石破天惊的文章：Recursive Programming，于是人们才知道，原来高级语言也可以高效地实现递归，原来从此以后，所有程序员都不可避免地和戴爷爷发明的一个词(应该说是概念)打交道：堆栈。而且Algo60还让戴爷爷深入地思考多道程序设计的问题，最终发明了每个系统程序员都绕不开的概念：semaphore。当然，戴爷爷总是把他发明的概念严格形式化，极具科学家本色的说。和这些成就想比，他提出的吃饭的哲学家问题，也就没什么好说的了。说来好笑，当时的大学(忘了哪所了)还是觉得戴爷爷没有受过正统的数学训练，也不是专门搞数值分析的，所以最后不太情愿地给了他一个教职。这种小挫折并不能妨碍象戴爷爷这样的牛人创造历史。他一边教数值分析(:-D)，一边开始开发一个新的操作系统，并培养计算机科学家。几年后，THE Multiprogramming System横空出世。THE是第一个支持松散耦合，显式同步的进程并由此使得严格证明系统没有死锁变得容易的操作系统。可惜戴爷爷任职的系不识货，还强行解散了他的研究小组(1972年戴爷爷给他的系主任说他得了图灵奖，系主任的第一反应是你们搞计算机就喜欢乱发奖)。这让戴爷爷相当郁闷，得了抑郁症。在极度郁闷之中，戴爷爷决定用写作来治疗自己的抑郁症。于是经典就诞生乐：Notes on Structured Programming。戴爷爷从此被尊为结构化编程的奠基人，而且他的抑郁症也被治好乐。EWD太牛，结果他的故事也太多。先到这里吧。1973起，他的故事就在美国发生了。

I've been programming a lot of ATtinys for my TinyTX sensors so made up this ZIF programming shield using a scrap of stripboard to make things easier.
