項目簡介

為什么叫創(chuàng)世一號（WorldEdit）呢？因為想著以后用這把鍵盤，闖蕩天下，制造更多東西，就像一個創(chuàng)世神一樣，所以就叫創(chuàng)世一號WorldEdit了

創(chuàng)世一號采用STM32F103RCT6主控，整合有鋰電池充放電管理，穩(wěn)壓，藍牙串口HID，USB-HID，LED燈陣列驅動，按鍵檢測電路。可實現(xiàn)藍牙連接模式（支持IOS、Android等平臺），和USB連接模式。藍牙連接時響應時間約15ms，USB連接模式主控響應時間約為0.3Ms。

靚照如下：

一、準備材料階段

1.鍵盤配列

首先做機械鍵盤，需要了解鍵盤的配列。制作配列有很多工具可以用，我們在這一步需要把定位板的CAD圖生成，用到以下兩個網(wǎng)站：

配列編輯網(wǎng)站： http://www.keyboard-layout-editor.com/

定位板CAD生成網(wǎng)站：

http://builder.swillkb.com/

如果要做的配列和我的一樣，可以直接使用我的配列CAD文件,我要做的配列如下：（這個網(wǎng)站可以很方便的修改配列，網(wǎng)上教程已經(jīng)很多了，我就不詳細介紹了）

然后將你的配列的Raw data復制到CAD生成網(wǎng)站。生成CAD定位板文件（該文件在畫PCB和鍵盤外殼都需要用到）

然后底下的這些是和軸體有關的，一般來說默認就行了。

點擊

生成文件，然后點擊右上DXF并將文件下載保存。

到這里，鍵盤配列就完成了。然后去網(wǎng)上沖浪淘一淘，買鍵帽、藍牙HID模塊、主控啊、一些電容電阻啊、鋰電池啊、等等需要用到的東西。

2. 元器件、模塊、電池、軸體、鍵帽等采購

我的整個鍵盤需要的物品清單如下：

器件購買完畢后，就可以開始畫電路了（不會的可以用我的PCB去加工，我100元做了5張PCB）由于整個項目都已開源，這里就不介紹具體電路了。

然后是設計外殼。由于沒有加工條件，只能網(wǎng)上訂制，所以就簡單的設計了一個不包底的鋼板做框架。最后成品也還可以。

二、組裝調(diào)試

以上都準備完成后，就是焊電路，裝軸，上鍵帽了。具體步驟，可以看我的制作視頻。

三、優(yōu)化程序代碼

代碼部分的思路就是檢查鍵盤消息是否更新，更新了就生成按鍵數(shù)據(jù)包，然后串口傳輸給藍牙模塊。如果是USB模式的話就直接USB發(fā)送給電腦主機。按鍵物理上如何快速與程序代碼鏈接起來呢，這里有一個思路，如果有更好的方法或建議請留言或私信，謝謝啦。這里將按鍵的位置與數(shù)組的順序對應了起來，在后面處理按鍵消息的時候用起來很方便。
