IV-18 Arduino Shield 製作


於是,IV-18 時鐘的Arduino 版登場啦~~~
經過快半個月的時間這張板子終於到了我手上,沒辦法,我真的找不到有哪一家比OSHPark便宜的PCB製作廠了

好啦,言歸正傳,這次的版本沿用http://forum.43oh.com/topic/2487-siv-18-vfd-clock-booster-pack/大致上的Layout,但是增加了DS1307 RTC,然後5V可以直接從Arduino拉過來.
首先,先上MC34063,MAX6921,DS1307,By the way,我的DS1307還沒到所以右下角沒焊接

SOIC應該不會很難焊,圖片稍微放大一點就可以發現我的焊工根本___
再來上電阻,二極體,可變電阻
剩下電容,電感,電池座和針母上完後,主體大致上就完成了
然後不想等DS1307只好把手邊的RTC模組拆了(=ﾟωﾟ)ﾉ
右下角就全補齊了

再來先插上Arduino測試MC34063升壓得如何
測量點是二極體的輸出端,電壓大概20~30V就可以了,太高太低就轉可變電阻
之後換重頭戲,IV-18的轉接版~
英文不錯的話就看http://learn.adafruit.com/ice-tube-clock-kit/board-assembly這裡其中的IV-18部分吧

先上90度的雙排針,這點需要非常注意,排針要從右手邊插,如圖,如果插了的話會"非常麻煩"喔
接下來就是上IV-18
上板子之前,最好先把他的腳給剪一剪,繞一圈長度越來越短,這樣的話會比較好上去
注意到了嗎?中間有三個PIN腳是沒有功能的,這三隻PIN要插到標示在PCB上三個"NC"的地方
,插進去後,先不要焊接,把Program upload到Arduino上面,再把這個板子插到Shield上測試
測試完成後再焊接.
Program is here:GITHUB

焊接完就大功告成啦~

後來順便改一下電路板把一些缺點修一修
把有點占空間的電池座換了一個,然後有多的空間讓DS3231放背面,還有蜂鳴器也可以直接放在板子上,電感挪到MC34063旁邊
不過電池彈片還真難買.....光華繞了大半圈都沒有,只好從RS叫貨了

另外就是我發現MAX6921只能叫貨.....非常不方便,尤其是我手邊的6921快沒了
所以只好另尋他法
希望這版能測試成功

==Update==
程式碼加入了調整時間的直接方式
先輸入大寫的S,就可以進到調整時間的程式

      PCB有的賣
      IC去申請Sample吧～
      管子上ebay買一兩支含運也兩三百左右
