|
7 | | -主要内容如下： |
| 7 | +The STM32F411xC/xE devices are based on the high-performance Arm® Cortex® -M4 32-bit RISC core operating at a frequency of up to 100 MHz. The Cortex®-M4 core features a Floating point unit (FPU) single precision which supports all Arm single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) which enhances application security. |

| 9 | +The STM32F411xC/xE belongs to the STM32 Dynamic Efficiency™ product line (with products combining power efficiency, performance and integration) while adding a new innovative feature called Batch Acquisition Mode (BAM) allowing to save even more power consumption during data batching. |
| 10 | +The STM32F411xC/xE incorporate high-speed embedded memories (up to 512 Kbytes of Flash memory, 128 Kbytes of SRAM), and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB bus and a 32-bit multi-AHB bus matrix. |
| 11 | +All devices offer one 12-bit ADC, a low-power RTC, six general-purpose 16-bit timers including one PWM timer for motor control, two general-purpose 32-bit timers. They also feature standard and advanced communication interfaces. |
| 12 | +The STM32F411xC/xE operate in the - 40 to + 125 °C temperature range from a 1.7 (PDR OFF) to 3.6 V power supply. A comprehensive set of power-saving mode allows the design of low-power applications. |
| 13 | +These features make the STM32F411xC/xE microcontrollers suitable for a wide range of applications. |

56 | | -### 快速上手 |
57 | | - |
58 | | -本 BSP 为开发者提供 MDK5 和 IAR 工程，并且支持 GCC 开发环境。下面以 MDK5 开发环境为例，介绍如何将系统运行起来。 |
59 | | - |
60 | | -#### 硬件连接 |
61 | | - |
62 | | -使用 Type-A to Mini-B 线连接开发板和 PC 供电，红色 LED LD3 (PWR) 和 LD1 (COM) 会点亮。 |
63 | | - |
64 | | -#### 编译下载 |
65 | | - |
66 | | -双击 project.uvprojx 文件，打开 MDK5 工程，编译并下载程序到开发板。 |
67 | | - |
68 | | -> 工程默认配置使用 ST-LINK 下载程序，点击下载按钮即可下载程序到开发板。 |
69 | | -
|
70 | | -#### 运行结果 |
71 | | - |
72 | | -下载程序成功之后，系统会自动运行，观察开发板上 LED 的运行效果，红色 LD3 和 LD1 常亮、绿色 LD2 会周期性闪烁。 |
73 | | - |
74 | | -USB 虚拟 COM 端口默认连接串口 2，在终端工具里打开相应的串口（115200-8-1-N），复位设备后，可以看到 RT-Thread 的输出信息: |

83 | | -### 进阶使用 |
84 | | - |
85 | | -此 BSP 默认只开启了 GPIO 和 串口 2 的功能，更多高级功能需要利用 ENV 工具对 BSP 进行配置，步骤如下： |
86 | | - |
87 | | -1. 在 BSP 下打开 env 工具。 |
88 | | - |
89 | | -2. 输入 `menuconfig` 命令配置工程，配置好之后保存退出。 |
90 | | - |
91 | | -3. 输入 `pkgs --update` 命令更新软件包。 |
92 | | - |
93 | | -4. 输入 `scons --target=mdk4/mdk5/iar` 命令重新生成工程。 |
