瘋狂加班

最近因為 G Sensor正夯
很多東西的應用都加上了 G Sensor
剛好新案子也是用 G Sensor

因為是剛接觸 G Sensor
很多控制設定都還未測試過
HK又趕著要
雖然這個案子不是由我開發
但........盡在不言中 囧

連續14天半夜2到4點下班
到隔天10點的也有
只能說累啊 ~_~

AVR Usb Programming

最近在網路上找到新的AT89S5x Programmer
剛好也看到AVR USB Programmer
就試著把它們做出來
測試的結果是ok的
也能正確燒寫

Easy spi......Print port 簡易電路
SPI progrma...增加74ls244穩定用，有分USB POWER AND PRINT POWER
使用軟體 Spipgm or Ponyprog

AVR USB Program...Usb Program
需要使用燒寫器先將usb程式寫入Atmega8
插上USB後電腦會辨視出Device
安裝Drive
使用Avrdude將程式寫入Mcu

遇到的問題是全新的Atmega8
使用Usb萬用燒錄器將程式寫入後
電腦還是無法辨視
但使用Print port寫入後
卻可正常辨視
之後不管使用usb萬用燒錄器還是Print寫入
都能正常執行

參考網站
Usbasp
Avrdude
Avrdude-gui

以下我修改後的電路圖

Easy stocks system

因為小弟需要
所以用三天寫一個簡易的股票小系統
很久沒用BCB寫程式

所以很多小細節沒有注意到
目前只是個簡易的功能
沒有錯誤提示

輸入股票代碼
按find
之後auto up data才能開啟使用
每40秒自動更新一次
如需改秒數
請修改stock.ini裡的
ats=40000

如使用後有bug或需要改進的地方
請告訴我 謝謝

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
