STM32硬核DIY機(jī)械鍵盤|藍(lán)牙USB雙模|燈控
項(xiàng)目起因
想
項(xiàng)目簡(jiǎn)介
為什么叫創(chuàng)世一號(hào)（WorldEdit）呢？因?yàn)橄胫院笥眠@把鍵盤，闖蕩天下，制造更多東西，就像一個(gè)創(chuàng)世神一樣，所以就叫創(chuàng)世一號(hào)WorldEdit了
創(chuàng)世一號(hào)采用STM32F103RCT6主控，整合有鋰電池充放電管理，穩(wěn)壓，藍(lán)牙串口HID，USB-HID，LED燈陣列驅(qū)動(dòng)，按鍵檢測(cè)電路?？蓪?shí)現(xiàn)藍(lán)牙連接模式（支持IOS、Android等平臺(tái)），和USB連接模式。藍(lán)牙連接時(shí)響應(yīng)時(shí)間約15ms，USB連接模式主控響應(yīng)時(shí)間約為0.3Ms。
靚照如下：
一、準(zhǔn)備材料階段
1.鍵盤配列
首先做機(jī)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?cè)谶@一步需要把定位板的CAD圖生成，用到以下兩個(gè)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(gè)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(xì)介紹了）
然后將你的配列的Raw data復(fù)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(guān)的，一般來(lái)說(shuō)默認(rèn)就行了。
點(diǎn)擊
生成文件，然后點(diǎn)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(lán)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(gòu)
我的整個(gè)鍵盤需要的物品清單如下：
器件購(gòu)買完畢后，就可以開始畫電路了（不會(huì)的可以用我的PCB去加工，我100元做了5張PCB）由于整個(gè)項(xiàng)目都已開源，這里就不介紹具體電路了。
然后是設(shè)計(jì)外殼。由于沒(méi)有加工條件，只能網(wǎng)上訂制，所以就簡(jiǎn)單的設(shè)計(jì)了一個(gè)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(zhǔn)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(lán)牙模塊。如果是USB模式的話就直接USB發(fā)送給電腦主機(jī)。按鍵物理上如何快速與程序代碼鏈接起來(lái)呢，這里有一個(gè)思路，如果有更好的方法或建議請(qǐng)留言或私信，謝謝啦。這里將按鍵的位置與數(shù)組的順序?qū)?yīng)了起來(lái)，在后面處理按鍵消息的時(shí)候用起來(lái)很方便。
