AT89S5X easy demo

公司同事功能上的測試
需要另一個mcu做簡單的功能
剛好就用51來做

AT89S5x + SS2A16 LCM

使用 SDEC 的 LMC-SS2A16
和網路上的 LMC-SSC2A16
是同樣的所以可參考同一份PDF


想做這個是以後可用一個簡易的LCD
當做Debug使用
因為沒有ICE ~_~
所以就用變通的方法
最少這樣還能簡易的除錯
還不錯用

AT89S5X + G_SENSOR

G_SENSOR 使用的是BOSH BMA020
通訊介面是用I2C
由於89s5x沒有提供硬體I2C介面
所以就用軟體模擬

程式只是試驗用的
所以沒有寫的很嚴謹
如果G_SENSOR有問題的話
整個程式會當在ACK
有需要的人可自已在改寫
INT腳未拉出

電容換算

有時拿到電容時
還要細看編號
對於我們這種較笨的人
還要拿個紙筆計算一下
還會算錯才囧


因為同事的建議就寫了這個簡易換算程式
只要輸入電容編號就ok
但不能反算
因為是簡易的 XDD

這次提供了 DOS 和 WINDOWS 二種版本
之前的RGB轉換也有小改

我願意

王菲
是我最欣賞的藝人
喜愛她的歌聲
特別是早期的作品
常讓我回味

天空......一張很舊的專輯
但..很好聽

王菲 我願意

思念是一種很玄的東西，如影隨形
無聲又無息出沒在心底，轉眼.....吞沒我在寂寞裡
我無力抗拒，特別是夜裡......哦~~想你到無法呼吸
恨不能立即朝你狂奔去 大聲的告訴你.......
我願意為你....忘記我姓名
就算多一秒，停留在你懷裡，失去世界也不可惜
我願意為你....被放逐天際
只要你真心，拿愛與我回應，我什麼都願意...什麼都願意......為你！

思念

原來對人，對物的思念
能夠這麼的清悉

或許是第一次來到外鄉
一切總是陌生，孤獨

對人，想念那種溫暖的擁抱
對物，想念那種熟悉的環境

我是那麼想妳......
