A very good IMU (attitude measurement unit) learning kit

This is a very good IMU (attitude measurement unit) learning kit I bought from Taobao. It is very easy to understand for beginners. The STM32F103 main controller integrates MPU-6050 (integrated 3-axis gyroscope and 3-axis accelerometer), HMC5883L (3-axis geomagnetic sensor), BPM085 (barometric altimeter, the sensor has a resolution of 0.03hPa and 0.25 meters in high linear mode, which can meet the height detection of robot indoor stair climbing), STM32F103T8 (32-bit ARM CortexM3 processor running at 72M clock) STM32_AHRS_WorkDir\\\\1.MPU6050Test\\\\HardWareDriver\\\\BMP085\\\\BMP085.c ..................\\\\.............\\\\..............\\\\......\\\\BMP085.h ..................\\\\.............\\\\..............\\\\delay.c ..................\\\\.............\\\\..............\\\\delay.h ..................\\\\.............\\\\..............\\\\HMC5883L\\\\HMC5883L.c ..................\\\\.............\\\\..............\\\\..............\\\\HMC5883L.h ..................\\\\.............\\\\..............\\\\IMU\\\\IMU.c ..................\\\\.............\\\\..............\\\\...\\\\IMU.h ..................\\\\.............\\\\..............\\\\IOI2C.c ..................\\\\.............\\\\..............\\\\IOI2C.h ..................\\\\.............\\\\..............\\\\LED\\\\LED.c ..................\\\\.............\\\\..............\\\\...\\\\LED.h ..................\\\\.............\\\\..............\\\\MPU6050\\\\MPU6050.c ..................\\\\.............\\\\..............\\\\.......\\\\MPU6050.h ..................\\\\.............\\\\..............\\\\UART2\\\\UART2.c ..................\\\\.............\\\\..............\\\\.....\\\\UART2.h ..................\\\\.............\\\\..............\\\\....s\\\\UARTs.c ..................\\\\.............\\\\..............\\\\.....\\\\UARTs.h ..................\\\\.............\\\\JLinkLog.txt ..................\\\\.............\\\\JLinkSettings.ini ..................\\\\.............\\\\Lib\\\\inc\\\\misc.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_adc.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_bkp.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_can.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_cec.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_crc.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_dac.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_dbgmcu.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_dma.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_exti.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_flash.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_fsmc.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_gpio.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_i2c.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_iwdg.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_pwr.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_rcc.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_rtc.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_sdio.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_spi.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_tim.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_usart.h ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_wwdg.h ..................\\\\.............\\\\...\\\\Release_Notes.html ..................\\\\.............\\\\...\\\\src\\\\misc.c ..................\\\\.............\\\\...\\\\stm32f10x_adc.c ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_bkp.c ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_can.c ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_cec.c ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_crc.c ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_dac.c ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_dbgmcu.c ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_dma.c ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_exti.c ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_flash.c ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_fsmc.c ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_gpio.c ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_i2c.c ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_iwdg.c ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_pwr.c ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_rcc.c ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_rtc.c ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_sdio.c ..................\\\\.............\\\\...\\\\...\\\\stm32f10x_spi.c ..................\\\\.............
