攪左差唔多 2 星期既 KS0108 LCD
#yeah# 幾時可以將塊 Bread Board 轉成 PCB ? #photo# 已經轉左了！#ham_sub#第一張一排黃線果塊已經係…有埋 IC，今朝影的…
面包板係 2-13 係 lab 影… 廢機影廢相… o甘係時候簡化 o的線 & 寫個 user friendly 的 program 出來了 #yeah# #eh#我而家玩緊bs2 [quote]原帖由 [i]觀星是答案[/i] 於 2007-2-24 10:52 發表
o甘係時候簡化 o的線 & 寫個 user friendly 的 program 出來了 #yeah# [/quote]應該唔會了…
就係 program 佢出個溫度同時間已經寫左 1 星期…#bye#
佢係 graphical lcd，入面冇文字的！
因此要好似 php 咁 load ttf 檔用 gd 將文字變成 wbmp 圖，然後再寫多個 program load 個 wbmp 黎 show 圖！ 仲咩唔用你部 dslr 影 ??? 塊LCD係邊度買架? 幾$? 華輝 $300 [quote]原帖由 [i]閒魂[/i] 於 25/2/2007 01:14 發表

CLCD also buy in 華輝? How much? CLCD 係 W Core 問呀蛇拎的！
上面全部 source 都係 complied from linux gcc and for linux
CLCD 果個可以試下改改佢…應該可以用 VS Compile！
另外 WinXP 唔比用 Program 直接 access hardware… [quote]原帖由 [i]閒魂[/i] 於 2007-2-27 14:24 發表
