說明
------
國立成功大學資訊工程系/所自 2012 年，開設一系列`嵌入式系統相關課程</embedded/schedule>`_，選定 STM32 硬體作為教材，過程中師生共同撰寫技術文件、範例程式碼、工具程式、作業系統核心，以及具體而微的專案，這些都以開放內容、開放原始碼的形式釋出，一方面希望社會各界能夠給予批評指教，另一方面也希望讓學生們日後有更多的選擇機會。

* 官方訓練教材: `STM32F429 CombinedModules</embedded/STM32F429-CombinedModules.pdf>`_ (必讀!)
* STM32F429ZIT6 microcontroller featuring 2 MB of Flash memory, 256 KB of RAM in an LQFP144 package
* On-board ST-LINK/V2 with selection mode switch to use the kit as a standalone
* ST-LINK/V2 (with SWD connector for programming and debugging)
* Board power supply: through the `USB</embedded/USB>`_ bus or from an external 3 V or 5 V supply voltage
* 2.4" QVGA TFT LCD
* SDRAM 64 Mbits
* L3GD20, ST MEMS motion sensor, 3-axis digital output gyroscope
* Six LEDs:
  - LD1 (red/green) for USB communication
  - LD2 (red) for 3.3 V power-on
  - Two user LEDs:LD3 (green), LD4 (red)
  - Two USB OTG LEDs:LD5 (green) VBUS and LD6 (red) OC (over-current)

* Two pushbuttons (user and reset)
* USB OTG with micro-AB connector
* Extension header for LQFP144 I/Os for a quick connection to the prototyping board and an easy probing
