3 RPi - Explorer700 12. Installing the additional libraries In order to use the API examples we provide, related libraries are required, which should be installed manually. bcm2835 Libaries wiringPi Libraries 12.1 wiringPi Library Click here to download the wiringPi libraries. You can also download them from the wiringPi website: https://projects.drogon.net/raspberry-pi/wiringpi/download-and-install/ Copy the installation-package with a usb-stick to your system.
3 RPi - Explorer700 12.3 Python Library You can receive the python libraries for Raspbian (contains RPi, GPIO and spidev) by using the apt-get command. Please note that your Raspberry Pi needs to be connected to the internet to install the libaries. Use the following command the make sure that you are going to receive the latest packages. sudo apt-get update Enter the following command to install the python-dev package: sudo apt-get install python-dev Now you can install the package: sudo python setup.
3 RPi - Explorer700 12.4 Configurating the interfaces (Before executing the API codes, you need to activate the core-drivers of the specific interfaces. The I2C and SPI core-drivers are already activated by default. Also the I2C and SPI drivers are active. But the serial port is still in its debug-mode. To enable the I2C functions, enter the following command: sudo raspi-config Choose Advanced Options -> I2C -> Yes You also need to modify the configuration-file.
3 RPi - Explorer700 Chosoe Advanced Options -> Serial. Choose NO. Reboot your system aferwards. Note: The serial port auf the Raspberry Pi 3 Model B is not useable because Pin 14 and 15 is connected with the build in Bluetooth-Module. To activate the SPI functions, enter the following command: sudo raspi-config Choose Advanced Options -> I2C -> yes. Ausgabe 22.09.
