+# Smart Belt Based On Neural Network
+This application is a specific example of using the smart belt to monitor human health.
+This application uses the smart belt to detect the user's heart rate, get exercise status by neural network and use voice to control the belt function to obtain information such as ambient temperature and our physical condition. What's more, these information can be sent to the mobile phone through Bluetooth.

+## Introduction
+### Function
+The smart belt based on neural network mainly realizes the following functions:
+Main functions: motion state recognition, heart rate detection, voice control and voice reminder.
+Other functions: ambient temperature and humidity detection, Bluetooth transmission.
+In this project, we use 9D sensor (mpu-9250) built in arc iotdk development board to realize motion state recognition based on neural network; Use pulse sensor heart rate sensor to detect heart rate; Ld3320a voice recognition module and syn6288 voice synthesis module are used to realize voice control and voice reminder; DHT11 temperature and humidity sensor is used to detect ambient temperature and humidity; Use hc-5 Bluetooth module to realize Bluetooth transmission.
+The detailed control commands are as followed:
+
+| Command                  | Voice(Chinese Pinyin)      |
+| ------------------------ | -------------------------- |
+| Temperature and Humidity | "wen du"                   |
+| Heart Rate               | "xin tiao"                 |
+| Motion State             | "zhuang tai"               |
+| Stop Alarm               | "jie su"                   |

+## User Manual
+### Before Running This Application
+1. If you want to transfer the data to the mobile phone,please download [BlueSPP](https://pan.baidu.com/s/1lNGEwsjWSztfxqkhomAPlg) on the phone.
+
+### Run This Application
+Before programming IoTDK, PMOD mux must be configured in order to use bus drivers of IoTDK.
+This operation is to make the ADC port work normally.
+```c
+// In file "embarc_osp-embarc_mli\embarc_osp-embarc_mli\board\iotdk\drivers\mux\mux.c"
+void io_mux_init(void)
+{
+	sysconf_reg_ptr->PMOD_MUX = 0;
+	sysconf_reg_ptr->ARDUINO_MUX = 1;
+}
+```
+
+Makefile target options about IoTDK and toolchain:
+```makefile
+APPL ?= smartbelt
+BOARD ?= iotdk
+EXT_DEV_LIST += sensor/imu/mpu9250
+CUR_CORE = arcem9d
+APPL_DEFINES = -DUSE_APPL_MEM_CONFIG -DV2DSP_XY -DMODEL_BIT_DEPTH=16 -g
+TOOLCHAIN ?= gnu
+OLEVEL = O0
+```
+
+Directories of source files and header files:
+
+```makefile
+EMBARC_ROOT = ../../..
+
+# use -Hpurge option to optimize the code size
+ifeq ($(TOOLCHAIN), gnu)
+ADT_COPT += -ffunction-sections -fdata-sections
+ADT_LOPT += -Wl,--gc-sections
+else
+ADT_COPT += -Hpurge
+ADT_LOPT += -Hpurge
+endif
+
+LIB_SEL = embarc_mli
+MID_SEL = common
+
+# application source dirs
+APPL_CSRC_DIR = . model
+APPL_ASMSRC_DIR = .
+
+# application include dirs
+APPL_INC_DIR = . model
+
+# include current project makefile
+COMMON_COMPILE_PREREQUISITES += makefile
+
+### Options above must be added before include options.mk ###
+# include key embARC build system makefile
+include $(EMBARC_ROOT)/options/options.mk
+```
+
+Then `make run`
