How to use it
We provide demo codes for easy testing, you can download the demo codes from #Resources
Unzip the archive downloaded to get the codes.
Raspberry Pi
- Insert the Micro SD card of Raspberry Pi to host PC.
- Copy the RapberryPi folder to boot directory of the micro SD card.
- Start your Raspberry Pi with the Micro SD card
- You can find that the RaspberryPi codes are saved in the BOOT directory.
- Copy the folder to home directory
sudo cp -r /boot/RaspberryPi/ ./ sudo chmod 777 -R RaspberryPi/ cd RaspberryPi
- BCM2835:
wget http://www.airspayce.com/mikem/bcm2835/bcm2835-1.64.tar.gz sudo tar zxvf bcm2835-1.64.tar.gz cd bcm2835-1.64 sudo ./configure sudo make sudo make check sudo make install
- Install wiringPi
sudo apt-get install git sudo git clone git://git.drogon.net/wiringPi cd wiringPi sudo ./build
- Install python
sudo apt-get install python-pip sudo pip install RPi.GPIO sudo pip install spidev sudo apt-get install python-imaging sudo apt-get install python-smbus sudo apt-get install python-serial
- Enable I2C
sudo raspi-config
- Choose Interfaceing Options -> I2C -> Yes
- Hardware connection
The colors of wires may be different, please connect it according to the silk screen printing.

=STM32 examples
The STM32 examples is based on Waveshare XNUCLEO-F103RB whose chip is STM32F103RB, HAL libraries.
- Hardware connection
Connect the sensor to STM32 board according the table, then connect USB to UART interface of XNUCLEO board to host PC.
