1、开发板的话STM32F429IDISCOVERY
The STM32F429 Discovery helps you to discover the high-performance microcontrollers of the STM32 F4 series and to develop your applications easily.
It offers everything required for beginners and experienced users to get started quickly.
Based on the STM32F429ZIT6, it includes an ST-LINK/V2 embedded debug tool, a 2.4" QVGA TFT LCD, an external SDRAM of 64 Mbits,
a gyroscope ST MEMs, a USB OTG micro-AB connector, LEDs and pushbuttons.
Key Features
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 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 D1 (red/green) for USB communicationLD2 (red) for 3.3 V power-onTwo user LEDsD3 (green), LD4 (red)Two USB OTG LEDsD5 (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
