+## TencentOS-tiny_Person_Detection_Demo
+
+### 1. 目录结构：
+
+- TencentOS-tiny\board\NUCLEO_STM32L496ZG\BSP\Hardware : **外设驱动代码**
+- TencentOS-tiny\examples\tflitemicro_person_detection : **Demo任务函数**
+- TencentOS-tiny\board\NUCLEO_STM32L496ZG\KEIL\tflitemicro_person_detection : **keil工程**
+- TencentOS-tiny\components\tflite_micro\tensorflow : **tflite_micro代码**
+
+### 2. 完成的工作：
+
+- 使用STM32CubeMX，选择与TOS同版本的固件库重新生成外设初始化代码；
+- TOS、摄像头和LCD工作都正常工作；
+
+### 3. 未完成的工作：
+
+- tflite_micro 以component的形式加到工程
+- 串口重定向用了TOS的方法，retarget.c还没有引入工程
+- 变量名、函数名还没有按照TOS的风格完全统一

+;* 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.
