Description
The Maple board consists of the essentials: a fast processor with lots of peripherals. At the center of Maple is a 72MHz ARM Cortex M3 chip, providing the increased computational power desired by more advanced users. In the past, ARM processors were notoriously unfriendly in non-professional environments due to proprietary tool chains and unfamiliar instruction sets. Because of this, they were conspicuously absent from classrooms and hobbyists’ workbenches. Leaf aims to change this by providing an ARM tool-chain built from open source components and a programming environment that is intuitively easy to use. For those of us who love and are familiar with Arduino, Maple is offered in an Arduino-compatible format, complete with Arduino pin layouts and programming environment. In the future, a Cortex native version is available in order to take full advantage of this fantastic micro-controller.
Board Overview
The Leaf Maple is a microcontroller board based on the STM32F103RB microprocessor. The Maple runs at a maximum of 72 MHz, has 39 digital input/output pins, 16 analog inputs, native full speed USB, 3 USARTs (hardware serial ports), integrated SPI/I2C support, a power jack, and a reset button. Maple is programmable over USB via our provided DFU bootloader, no extra hardware required! Users can also program the onboard program flash via external JTAG interface. Maple offers security support for read/write protected addresses, as well as User and Handler processor modes. It has a real-time sysTick, useful for a real time OS or any timing sensitive applications. 6 advanced interrupt timers will help you here as well. Maple can be powered via USB, a wall adapter, or it can run off of a rechargeable lipo battery (see below for more info). The Maple is compatible with shields designed for the Arduino Duemilanove or Diecimila.

Maple is a great way to get started with an advanced 32 bit-processor that, until now, has principally lived in the commercial domain. Take your projects to the next level with Maple’s fast clock, sophisticated interrupt architecture, and loads of built-in peripherals.
Programming
Maple can be programmed using an Arduino-style, sketch-based programming environment, which is open-source and can be downloaded online at our website. The Cortex-M3 on Maple comes pre-programmed with a boot-loader – allowing users to upload new code onto it using the USB interface (supported directly by the Cortex-M3), without the need for an external hardware programmer. You can also program the microcontroller directly with an external JTAG interface.
描述
楓董事會由要領：有很多外設的高速處理器。在楓的中心是一個72MHz的的ARM Cortex M3芯片，提供更先進的用戶希望增加的計算能力。在過去，ARM處理器都是非專業環境不友好臭名昭著由於專有工具鏈和不熟悉的指令集。正因為如此，他們分別來自教室和業餘愛好者“工作台顯眼。葉旨在通過提供開源組件和編程環境是直觀方便地使用內置的ARM工具鏈改變這一點。對於我們這些誰愛和熟悉的Arduino的，楓是一個Arduino兼容的格式提供，完全與Arduino的引腳佈局和編程環境。在未來，皮質原生版本，以便採取這個夢幻般的微控制器充分利用可用。
主板全貌
葉楓是一個基於微控制器板STM32F103RB微處理器。楓運行在最大72兆赫，擁有39數字輸入/輸出引腳，16個模擬輸入，本地全速USB，3個USART（硬件串口），集成的SPI / I2C支持，電源插孔，和一個復位按鈕。楓樹是可編程的過通過我們提供的DFU引導程序的USB，無需額外的硬件！用戶還可以通過編程外部JTAG接口板載程序閃存。華普提供的讀安全支持/寫保護地址，以及用戶和處理程序處理器模式。它具有實時SYSTICK，對於實時操作系統或任何定時敏感的應用是有用的。 6高級中斷定時器將幫助你在這裡。楓可通過USB供電，牆上適配器，也可以關閉一個可充電鋰聚合物電池的運行（見下文的詳細信息）。楓葉是專為Arduino的Duemilanove或Diecimila罩。
