This document records the instruction of the BSP (board support package) that provided by the RT-Thread development team for the STM32F469-ST-DISCO development board.
By reading the ***Quickly Get Started*** section developers can quickly get their hands on this BSP and run RT-Thread on the board. More advanced features will be introduced in the Advanced Features section to help developers take advantage of RT-Thread to drive more on-board resources.
## 开发板介绍
## Resources Introduction
STM32F469-ST-DISCO 是 ST 推出的一款基于 ARM Cortex-M4 内核的开发板，最高主频为 180Mhz，该开发板具有丰富的板载资源，可以充分发挥 STM32F469 的芯片性能。
The STM32F469 Discovery kit allows users to easily develop applications with the STM32F469 high-performance MCUs with ARM®Cortex®-M4 core and Chrom-ART Accelerator™. The discovery kit enables a wide range of use cases taking advantage of premium graphics, audio, multi-sensor support, WVGA color display, security, memory extension and connectivity features.
- 常用接口：Arduino UNO V3 接口、MicroSD 卡接口、音频接口、LCD 接口、I2C 接口等
- 调试接口，板载的 ST-LINK/V2-1 SWD 下载

## Peripherals Condition
## 外设支持
Each peripheral supporting condition for this BSP is as follows:
This BSP provides MDK4, MDK5, and IAR projects for developers and it supports the GCC development environment. Here's an example of the MDK5 development environment, to introduce how to run the system.
使用说明分为如下两个章节：
#### Hardware Connection
- 快速上手
Use a cable to connect the development board to the PC and turn on the power switch.
> The project defaults to use the st-link emulator to download the program, and as we're connecting the development board via st-link, click the Download button can directly download the program to the development board.
#### Running Results
### 快速上手
After the program is successfully downloaded, the system runs automatically. The LED(LD1, Green) will flash.
Connect the corresponding serial port of the development board to the PC, and when the corresponding serial port ( 115200-8-1-N) is opened in the terminal tool, the output information of RT-Thread can be seen when the device is reset:
This BSP only enables GPIO and UART3 by default. If you need more advanced features such as SD Card, Flash, or you need to configure the BSP with RT-Thread homegrown [ENV tool](https://www.rt-thread.io/download.html?download=Env), as follows:
1. Open the ENV tool under the specific BSP folder;
2. Enter `menuconfig` command to configure the project, then save and exit;
3. Enter `pkgs --update` command to update the package;
4. Enter `scons --target=mdk4/mdk5/iar` command to regenerate the project.
