3 RPi - Explorer700 13. Libraries Installation for RPi In order to use the API examples we provide, related libraries are required, which should be installed manually. bcm2835 libraries wiringPi libraries 13.1 Install WiringPi Library Click to download the wiringPi libraries, or you can also obtain the latest version from the WiringPi website: https://projects.drogon.
3 RPi - Explorer700 13.3 Install Python Library Python Libraries for Raspbian (contain RPi.GPIO and spidev installation packages. See: https:// pypi.python.org/pypi/RPi.GPIO https://pypi.python.org/pypi/spidev ) get it by apt-get commands. Please take a note, your Raspberry Pi should be connected to the network when using the command apt-get to install the library. Before the installation, you can run the following command to update your software list. sudo apt-get update 1.
3 RPi - Explorer700 13.4 Configuring the interfaces (Before running the API codes we provided, you should start up the corresponding core drivers of the interfaces. In the ready-to-use system image file, both I2C and SPI are set to Enable by default, but the serial port is still in the terminal debugging function mode.) 1. Enable the I2C function. Run the following command to configure your Raspberry Pi board: sudo raspi-config Select Advanced Options -> I2C -> yes, to start up the I2C core driver.
