ATtiny Düşük Güç Modu

ATtiny uygulamarı genelde diğer mikroişlemciler ve geliştirme kartları ile yapılan uygulamardan epey farklı oluyor. Bu farklara sebep olan başlıca etmen ATtiny mikroişlemcilerinin küçük ve yetenekli olmasını söyleyebiliriz. Peki şu ana kadar yaptığınız ATtiny projelerinizde güç tüketimini neredeyse yarı yarıya azaltabileceğinizi söylesek ATtiny olan ilginiz artar mı? ATtiny düşük güç modu…

I recently bought an OLED display 128×64 from eBay (http://www.ebay.com/sch/i.html?_nkw=OLED+128) – very inexpensive (about 4 euro) but when I finally received it I was surprised to see how small it was – I was expecting something that looked more like the Nokia 3310 LCD. So I thought – this is perfect for the Tinusaur Project. The 128×64 OLED is controlled by a SSD1306circuit and could be…

Tutorial 002: Fading LED using PWM (pulse-width-modulation) technique.

Another beginners tutorial is on the way – this time about a fading in and out LED.

This is simple tutorial that shows how to connect a LED to the ATtiny85 based Tinusaur board and write a program that makes the LED to fade in and out using PWM (pulse-width-modulation) technique.

Note: The code in this tutorial does not use the built-in PWM capabilities of the ATtiny microcontrollers, instead it…

WinAVR is a great tool to do development for Atmel AVR micro-controllers on Microsoft Windows platform. It consists of all the necessary C/C++ compiler, linkers and other GCC tools that you need to write, build and program those micro-controllers. Here we have put together very short guide how to setup and use WinAVR for programming the Attiny85 micro-controller and the Tinusaur Board in particular.

Even though #Tinusaur is very simple it has its advantages as well as disadvantages that need to be discussed, here:

Is there anything special about this board? No! Absolutely nothing.

Even though the Tinusaur is a very simple thing it has its advantages as well as disadvantages that need to be addressed.

It is a platform that is simple and easy to understand for everyone – perfect for a quick start and in learning how to create things.

The board consists of the minimum required componentsfor…

The #Tinusaur Online Store is now OPEN so you can buy those Starter Kits. Make sure you've got your soldering iron hot and ready.

Finally, our online store is up and running.

We received some emails asking if we could offer the boards and the parts for purchasing … so we did it. We have to admit that it took us some time to arrange everything but some of the circumstances were beyond our control.

At the moment we have only one product listed – that’s the Tinusaur Starter.

為了喝牛奶, 需要養牛? 不必, 但是懂得養牛跟跑去養牛是不一定相關連的. 事緣為了記錄電池的充放電特性, 想抄一個現成的工具, 再來修修改改學習,

"The cheapest dual trace scope in the galaxy DIY made by ATtiny45" 這個源碼出自比利時的作者, 應該很就沒有活動, 原文如下 http://yveslebrac.blogspot.com/2008/10/cheapest-dual-trace-scope-in-galaxy.html

可是源碼供下載的地方斷了, 只有PC HOST 的 C# SOURCE CODE 可以下載, 還有就是那個 PNG SCHEMATIC, 其他都缺少....問了好幾個論壇, 終於得到了答案,

卻是同時引發了一個新的問號 ? 到底人家是如何在論壇上顯示一張圖片, 下載回來卻是實在的含有一個 ZIP 檔案呢 ? 如過俺也可以, 就可以直接把源碼包含在 wordpress 的記錄裡面, 方便閱讀與整理. 於是照樣劃葫蘆, 搜尋了GOOGLE, 了解 HOW-TO 以後, 實驗過, 部份論壇會截除這樣檔案, 只能下載圖片而已, 內包的 ZIP 會被自動除去. 部份卻是沒有問題. 那看看俺用的 Wordpress 有沒有這個功能, google 到的資料顯示的 blogpost 確定可以, 因為搜尋到的資料就有.

其是就是直接把 jpg + zip 包含在一起, 用的是 DOS 年代的指令 copy /b 或 linux 的 cat

Microsoft windows 或 DOS 就用以下的指令,

[sourcecode language="css"] copy /b my.jpg + my.zip out.jpg [/sourcecode]

這個指令的解釋如下 - 把 my.jpg 看成一串資料 (舉例, 如 "12345") 把 my.zip 看成第二串資料 (舉例, 如 "67890") 忠實並完整地使用 copy /b 這個指令, 把兩串資料接起來成為 "1234567890", 存在檔案 out.jpg 最後放到網站供下載, 用戶把 out.jpg 下載回來, 並且改名為 out.zip, Winzip 之類的軟件就會直接跳過內含的 my.jpg, 給你顯示需要的 my.zip

題外話, wordpress 內, 想要在文章裡突顯如上面的 source code, 今日找到方法 http://en.support.wordpress.com/code/posting-source-code/

[sourcecode language="css"] [sourcecode language="css"] your source code here1... your source code here2... [ /sourcecode] 註,最後的一句, [ /sourcecode], 因為要在此顯示, 需特意在 "[" 與 "/sourcecode]" 加上空格, 實際上要去除這空格 [/sourcecode]

所以, 俺現在會養這個牛, 也在文中可以清晰看到需要的指令, 看看哪個牧場可放牧, 需要放奶牛還是黃牛而已, 下面先試放俺要的這只奶牛, 共有兩個例子如下, 圖片是同一個, 都包含 rar 壓縮檔的一個 png 圖片檔,

下面這張png, 是用 ScribeFire 上傳的 USBscoperar.png 存檔後得到純粹的 png, source code 被截去, 存檔大小約 10K

而這下面的一張圖, 直接用 wordpress 網上編輯上傳 USBscoperar.png png + source code 完整且可下載恢復 source code 的 rar 存檔大小約299K, 把 USBscoperar.png 改名並去掉 .png, 得到 USB_scope.rar, 解開後就看到源碼, 成功!

[caption id="attachment1808" align="alignnone" width="418" caption="http://xiaolaba.files.wordpress.com/2012/04/usbscope_rar.png"][/caption]

      這是解開得到源碼的畫面, 源碼包括從不同來源收集的全部, 包括原作者網頁下載的 PC 端 C# 源碼, 還有 Clive68000 轉送給的 ATtiny45 的 FIRMWARE 源碼, 但是他們都出自原作者.

        ref :

GOOGLE 搜尋關鍵字以下, 說的都是相同的方法, 如何在一個 jpg png 等圖片內包含一個 zip 或 rar 壓縮檔, include image zip file, include png image zip file, image zip file include

這個仁兄的BLOG, 比較詳細描述原理和問題
