Linux for Cortex M3 & M4 Microcontrollers從前從前有三隻小豬，分別住在三個小屋裡。有一天，來了一隻大野狼，似乎有什麼不良的企圖。於是……大野狼首先來到了老大的家。大野狼說：哈哈，你以為鎖上了門就有用嗎？呼~~呼~~呼~~~~~老大的草屋根本就經不起大野狼的毒氣吹息而倒了。老大怕極了，跑丫~~跑丫~~，跑到了老二的@cnxsoft Hello, Clearly, the idea that you mention in your post is really interesting. However, to my knowledge, there is no Cortex-M3/M4 processor with more than 256kb of RAM and I don’t think that the situation will evolve. That’s why this chip from Fre...

Practical Advice on Running uClinux on Cortex-M3/M4 | Embedded content from Electronic Design一個全副武裝的老牛仔坐在酒吧裏喝酒，這時一位美女走入坐在他旁邊。稍刻，她轉過頭來問：「你真是牛仔嗎？」「我一生中一直忙於帶領牛群，馴服馬，修圍牆，我想你可以稱呼我為牛仔。」過了一陣子牛仔轉問：「妳呢？ 小姐。」「我從未去過牧場，我當然不是牛仔女，我是女同姓戀者。」她繼續：「我一生中一直忙於想女人，由What we at Emcraft Systems see happening in actuality defeats this argument, however.
