综述
STM32F4DISCOVERY
XiUOS最新分支支持stm32f407-st-discovery开发板，该开发板作为一种标准的板子，支持各种上层组件和应用程序。硬件特点
- STM32F407VGT6 microcontroller featuring 32-bit ARM®Cortex®-M4 with FPU core, 1-Mbyte Flash memory, 192-Kbyte RAM in an LQFP100 package
- On-board ST-LINK/V2 on STM32F4DISCOVERY (old reference) or ST-LINK/V2-A on STM32F407G-DISC1 (new order code)
- USB ST-LINK with re-enumeration capability and three different interfaces:
1. Debug port
2. Virtual Com port (with new order code only)
3. Mass storage (with new order code only)
+ Board power supply: through USB bus or from an external 5 V supply voltage + External application power supply: 3 V and 5 V + LIS302DL or LIS3DSH ST MEMS 3-axis accelerometer + MP45DT02 ST-MEMS audio sensor omni-directional digital microcontroller + CS43L22 audio DAC with integrated class D speaker driver + Eight LEDs:1. LD1 (red/green) for USB communication
2. LD2 (red) for 3.3 V power on
3. Four user LEDs, LD3 (orange), LD4 (green), LD5 (red) and LD6 (blue)
4. USB OTG LEDs LD7 (green) VBUS and LD8 (red) over-current
+ Two push-buttons (user and reset) + USB OTG FS with micro-AB connector + Extension header for all LQFP100 I/Os for quick connection to prototyping board and easy probing + Comprehensive free software including a variety of examples, part of STM32CubeF4 package or STSW-STM32068 to use legacy standard libraries.更多信息
