+
+## 概述
+
+本教程是基于STM32 NUCLEO-L496ZG（Cortex-M4, 80Mhz）开发板，在运行TencentOS tiny的基础上，使用Tensorflow Lite Micro框架和CMSIS-NN库（算子加速），在STM32L496ZG上实现了**行人检测模型**的推理。
+
+关于Tensorflow Lite Micro组件的详细介绍可以参考`TencentOS-tiny\components\ai\tflite_micro`目录下的TFlite_Micro_Component_User_Guide.md文档。
+
+本例程中，传入神经网络的RGB图像大小为 18kb（96*96 * 2byte），在STM32L496平台消耗的内存资源（经过优化后）如下：
+
+- SRAM：168 Kbyte
+- Flash：314 Kbyte
+
+理论上满足以上内存要求的STM32 Cortex-M系列MCU可以参考本指南进行移植。
+
+## 一、移植前的准备
+
+####   1. 准备目标硬件（开发板/传感器/模组）
+
+需要准备如下硬件：
+
+- 开发板：NUCLEO-L496ZG，MCU为STM32L496ZG；
+- Camera：获取RGB图像，本例程使用OV2640摄像头；
+- LCD：显示RGB图像，本例程使用2.4寸LCD（SPI通信）；
+
+硬件实物图如下：
+
+<div align=center>
+<img src="image/all.jpg" width=50% />
+</div>
+
+####   2.准备TencentOS tiny基础keil工程代码
+
+- 首先，参考TencentOS tiny基于keil的移植教程进行移植：
+  https://github.com/Tencent/TencentOS-tiny/blob/master/doc/10.Porting_Manual_for_KEIL.md
+- 为了方便初始化MCU的外设，后续要继续使用STM32CubeMX软件，请确保安装了该软件；
+
+- 移植成功后，工程可以进行线程任务切换，通过串口打印"hello world"，基础keil工程代码准备完毕。
+
+####   3. 获取Tensorflow Lite Micro
+
+有三种方式获取tflite_micro：
+
+1. 从TencentOS tiny 代码仓库 `components\ai\tflite_micro`目录获取；
+2. 以lib文件的形式使用tflite_micro组件，lib文件`TencentOS-tiny\components\ai\tflite_micro`的ARM_CortexM4_lib、ARM_CortexM7_lib和ARM_CortexM55_lib文件夹
+3. 从Tensorflow代码仓库获取，TFlite_Micro的源码已经开源，github仓库地址为：https://github.com/tensorflow/tensorflow ，可根据google TFLite Micro官方教程获得Tensorflow Lite Micro的全部源码。
+
+如果没有tflite_micro开发经验，建议以**第一种**或者**第二种**方式获取tflite_micro，希望自行获取最新源码，或者编译lib文件，请参考`TencentOS-tiny\components\tflite_micro`目录的TFlite_Micro_Component_User_Guide.md文档，本指南将直接使用TencentOS tiny 代码仓库内的tflite_micro组件。
+
+## 二、BSP准备
+
+### 1. 工程目录规划
+
+以下是整个例程的目录规划：
+
+| 一级目录  |           二级目录           |   三级目录   |                             说明                             |
+| :-------: | :--------------------------: | :----------: | :----------------------------------------------------------: |
+|   arch    |             arm              |              | TencentOS tiny适配的IP核架构（含M核中断、调度、tick相关代码） |
+|   board   |      NUCLEO_STM32L496ZG      |              |                    移植目标芯片的工程文件                    |
+|           |                              |     BSP      |            板级支持包，外设驱动代码在Hardware目录            |
+| component |              ai              | tflite_micro |                       tflite_micro源码                       |
+| examples  | tflitemicro_person_detection |              |                       行人检测demo示例                       |
+|  kernel   |             core             |              |                    TencentOS tiny内核源码                    |
+|           |              pm              |              |                 TencentOS tiny低功耗模块源码                 |
+|   osal    |           cmsis_os           |              |              TencentOS tiny提供的cmsis os 适配               |
+
+完成TencentOS tiny基础keil工程准备工作后，在这个keil工程的基础上继续添加外设驱动代码。
+
+### 2. LCD驱动
+
+本例程选用一款2.4寸LCD屏幕，分辨率为 240*320， SPI 接口通信，内部控制芯片为IL9341。
+
+开发者也可以使用其他LCD，自行完成LCD的驱动代码移植，方便调试摄像头，以及查看图像是否正常。
+
+#### 2.1 SPI初始化
+
+进入`TencentOS-tiny\board\NUCLEO_STM32L496ZG\BSP`目录，打开TencentOS_tiny.ioc工程，使用STM32CubeMX初始化MCU外设。
+
+<div align=center>
+<img src="./image/spi init.png" width=100% />
+</div>
+#### 2.2 打开keil的Manage Project Items
+
+<div align=center>
+<img src="./image/bsp_keil_manage_project.png" width=60% />
+</div>
+
+#### 2.3 在project中加入新的文件夹hal
+
+<div align=center>
+<img src="./image/bsp_添加hal.png" width=80% />
+</div>
+
+
+#### 2.3 添加驱动代码
+
+添加`lcd_2inch4.c`和`lcd_config.c`,
+
+<div align=center>
+<img src="./image/bsp_add lcd driver file.png" width=80% />
+</div>
+
+
+
+添加头文件`lcd_2inch4.h`和`lcd_config.h`路径
+
+<div align=center>
+<img src="./image/bsp_include_path.png" width=80% />
+</div>
+
+
+
+<div align=center>
+<img src="./image/bsp_include_lcd_path.png" width=80% />
+</div>
+外设驱动的头文件.h文件都在`TencentOS-tiny\board\NUCLEO_STM32L496ZG\BSP\Hardware\Inc`路径下。
+
+### 3. 摄像头驱动
+
+#### 3.1 外设初始化
+
+进入`TencentOS-tiny\board\NUCLEO_STM32L496ZG\BSP`目录，打开TencentOS_tiny.ioc工程，初始化DCMI外设，打开DCMI全局中断，并打开DMA通道，DMA的Direction设置为Peripheral To Memory。
+
+<div align=center>
+<img src="./image/bsp_cubemx_dcmi.png" width=100% />
+</div>
+
+<div align=center>
+<img src="./image/bsp_cubemx_dcmi_2.png" width=100% />
+</div>
+
+
+
+#### 3.2 添加驱动代码
+
+<div align=center>
+<img src="./image/bsp_add camera driver file.png" width=80% />
+</div>
+
+**在mcu_init函数重写DCMI帧中断回调函数：**
+
+值得注意的是，代码需要写在CubeMx生成的注释语句内，当使用CubeMX重新配置外设并生成代码时，所添加的代码才不会被覆盖掉，如下所示，代码添加在/* USER CODE BEGIN 4 */ 和 /* USER CODE END 4 */注释语句之间：
+
+```C
+/* USER CODE BEGIN 4 */
+void HAL_DCMI_FrameEventCallback(DCMI_HandleTypeDef *hdcmi)
+{
+	if(hdcmi->State == 2 && frame_flag != 1){
+		frame_flag = 1; 
+	}
+}
+/* USER CODE END 4 */
+```
+
+### 4. LCD显示摄像头图像
+
+本例程的任务函数在
+
+`TencentOS-tiny\examples\tflitemicro_person_detection\tflitemicro_person_detection.c`
+
+```c
+void task1(void *arg)
+{
+    while (1) {
+      if(frame_flag == 1){
+				
+				if(HAL_DCMI_Stop(&hdcmi))Error_Handler(); //stop DCMI
+				LCD_2IN4_Display(camera_buffer,OV2640_PIXEL_WIDTH,OV2640_PIXEL_HEIGHT);
+                //display
+				frame_flag = 0;
+				if(HAL_DCMI_Start_DMA(&hdcmi,DCMI_MODE_CONTINUOUS,\   //restart DCMI
+                                     (uint32_t)camera_buffer ,\
+					                 (OV2640_PIXEL_WIDTH*OV2640_PIXEL_HEIGHT)/2))
+                    Error_Handler(); 
+				osDelay(50);
+    }
+}
+```
+
+经过以上步骤，如果能顺利地驱动摄像头，并在LCD实时显示图像，BSP就准备完毕了，如果使用的是不同的LCD或者Camera，请根据实际情况进行外设初始化和驱动的移植。
+
+## 三、Tensorflow Lite Micro移植
+
+### 1. tflite_micro组件加入到keil工程
+
+由于NUCLEO-L496ZG芯片中的内核为ARM Cortex M4，所以本次我们可以直接使用ARM Cortex M4版本的tensorflow_lite_micro.lib库来简化tflite_micro搭建流程。
+
+#### 1.1 在project中加入新的文件夹tensorflow
+
+<div align=center>
+<img src="./image/tflu_tensorflow文件夹增加的内容.png" width=80% />
+</div>
+
+#### 1.2 添加本次与行人检测demo有关的源文件
+
+<div align=center>
+<img src="./image/tflu_需要添加的文件.png" width=80% />
+</div>
+
+
+
+其中，retarget.c的路径为：`TencentOS-tiny\components\ai\tflite_micro\KEIL\retarget.c`
+
+tensorflow_lite_micro.lib的路径为：`TencentOS-tiny\components\ai\tflite_micro\ARM_CortexM4_lib\tensorflow_lite_micro.lib`
+
+其余.cc文件均在当前目录下的`tflu_person_detection`文件夹中。
+
+#### 1.3 关闭Keil的MicroLib库
+
+<div align=center>
+<img src="./image/tflu_取消Microlib.png" width=80% />
+</div>
+
+#### 1.4 添加tflite_micro需要的头文件
+
+<div align=center>
+<img src="./image/tflu_添加include.png" width=80% />
+</div>
+
+注：最下方的路径为：
+
+```
+TencentOS-tiny\components\ai\tflite_micro\ARM_CortexM4_lib\tensorflow\lite\micro\tools\make\downloads
+```
+
+#### 1.5 调整优化等级和tflite_micro的交互信息输出串口：
+
+<div align=center>
+<img src="./image/tflu_STM32496宏.png" width=80% />
+</div>
+
+其中宏`NUCLEO_STM32L496ZG`是指定Nucleo STM32L496的hlpuart1为系统printf函数的输出串口，具体定义在Nucleo STM32L496的BSP文件夹中的`mcu_init.c`中。
+
+### 2. 编写Person_Detection 任务函数
+
+本例程的任务函数在
+
+`TencentOS-tiny\examples\tflitemicro_person_detection\tflitemicro_person_detection.c`目录下
+
+#### 2.1 图像预处理
+
+<div align=center>
+<img src="./image/RGB565.jpg" width=50% />
+</div>
+
+在本例程中，模型要求输入神经网络的图像为灰度图，为完成摄像头获取的RGB彩图到模型输入需要的灰度图转换，需从输入的RGB565像素格式中解析出R、G、B三通道的值，再根据心理学公式计算出单个像素点的灰度，具体代码如下：
+
+```c
+uint8_t rgb565_to_gray(uint16_t bg_color)
+{
+    uint8_t bg_r = 0;
+    uint8_t bg_g = 0;
+    uint8_t bg_b = 0;
+    bg_r = ((bg_color>>11)&0xff)<<3;
+    bg_g = ((bg_color>>5)&0x3f)<<2;
+    bg_b = (bg_color&0x1f)<<2;
+    uint8_t gray = (bg_r*299 + bg_g*587 + bg_b*114 + 500) / 1000;
+    return gray;
+}
+
+void input_convert(uint16_t* camera_buffer , uint8_t* model_buffer)
+{
+	for(int i=0 ; i<OV2640_PIXEL_WIDTH*OV2640_PIXEL_HEIGHT ; i++)
+	{
+		model_buffer[i] = rgb565_to_gray(camera_buffer[i]);
+	}
+}
+```
+
+#### 2.2 行人检测线程任务函数
+
+```c
+void task1(void *arg)
+{
+    while (1) {
+      if(frame_flag == 1){
+				printf("***person detection task\r\n");
+				if(HAL_DCMI_Stop(&hdcmi))Error_Handler(); //stop DCMI
+				input_convert(camera_buffer,model_buffer);//convert input
+				person_detect(model_buffer);              //inference
+				LCD_2IN4_Display(camera_buffer,OV2640_PIXEL_WIDTH,OV2640_PIXEL_HEIGHT);
+                //display
+        
+				frame_flag = 0;
+				
+				if(HAL_DCMI_Start_DMA(&hdcmi,DCMI_MODE_CONTINUOUS,\   //restart DCMI
+                                     (uint32_t)camera_buffer ,\
+					                 (OV2640_PIXEL_WIDTH*OV2640_PIXEL_HEIGHT)/2))
+                    Error_Handler(); 
+			}
+			osDelay(50);
+    }
+}
+
+void task2(void *arg)
+{
+    while (1) {
+        printf("***task2\r\n");
+        osDelay(50);
+    }
+}
+```
+
+#### 2.3 运行效果
+
+通过串行输出实时打印信息，移动摄像头，镜头没有对准行人时，输出如下：
+
+<div align=center>
+<img src="./image/reasult_no_person.png" width=70% />
+</div>
+
+当镜头对准行人时，输出如下：
+
+<div align=center>
+<img src="./image/reasult_person.png" width=70% />
+</div>
+
+执行一帧图像推理，耗时约633 ms。

+;* Description        : STM32L496xx Ultra Low Power devices vector table for MDK-ARM toolchain.
+;*                      This module performs:
+;*                      - Set the initial SP
+;*                      - Set the initial PC == Reset_Handler
+;*                      - Set the vector table entries with the exceptions ISR address
+;*                      - Branches to __main in the C library (which eventually
+;*                        calls main()).
+;*                      After Reset the Cortex-M4 processor is in Thread mode,
+;*                      priority is Privileged, and the Stack is set to Main.
