Preparation - installing the libraries required

Installing the libraries required

Before using the PIONEER600, you shall install the bcm2835, wiringPi and python libraries to the RPi to add the additional APIs, and configure the settings to start up the core drivers of I2C, SPI and UART after the libraries installed.

For simplicity reason, it is recommended to download the ready-to-use Image (Libraries pre-installed). Download password: t8aj. This image allows you to start Pioneer600 without installing the libraries.

For more detailed information about the installation and configuration of the RPI library functions, please refer to Libraries Installation for RPi.

When finished the configurations above, you need to download the sample programs from File:Pioneer600-Code.tar.gz, and unzip them to the directory of /home/pi (you can also copy them into the RPi board with your U-disk). Some of the sample programs can be implemented via different ways, such as the libraries of bcm2835, wiringPi, sysfs, python and so on. That means you can implement a same function by using different libraries. Therefore, the libraries of bcm2835, wiringPi and python should be installed to the RPi before used. In the next section, we will present the expansion functions provided by PIONEER600.

For more detailed information, please refer to the relative Raspberry Pi documents.

If the sample programs (download from File:Pioneer600-Code.tar.gz) presented in the next section are unable to be performed after installing the libraries, you can try to apply the command
chmod +x filename
to grant the program the executable permission.

Connecting the expansion board and the RPI

The Pioneer600 expansion board supports the Raspberry Pi A+ / B+ / 2 / 3 Model B. Before running the sample programs, please make sure the Pioneer600 is connected to the RPi and the RPi is powered up by the USB power supply. Without the RPi main board, the sample programs cannot be used on the expansion board.

Connected to Raspberry Pi Model A+: Connected to Raspberry Pi B+ / 2 / 3 Model B

How to use Pioneer600 with external sensor kits (purchased separately)

Using Pioneer600 with external sensor kits

Pioneer600 has four interfaces for external sensors, so that you can not only use the on-board sensors, but also other external sensors.

Before using the external sensors, you should:

  1. Connect the sensor kits to the expansion board, and install the expansion board to the RPi.
  2. Make sure that the libraries are installed and the I2C core driver is start up, since the on-board chip PCF8591 need to use the I2C interface to provide AD/DA function.
  3. Download the sample programs, and unzip them to the directory of /home/pi (you can also copy them into the RPi board with your U-disk).

  4. Run the following command to install the library serial, which contains UART interface functions
    sudo apt-get install python-serial
  5. Installing the library spidev (SPI functions). Copy the installation package spidev to your RPi board, and unzip it. Enter the unzip file under the terminal, and run the following command to install the library:
    sudo python setup.py install

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. Then you also need to modify the configuration file. Run the following command to open the configuration file:
    sudo nano /etc/modules
    Add the following two lines to the configuration file
    i2c-bcm2708
    i2c-dev
    Press the keys Ctrl+X to exit, and input Y to save the settings. Then, reboot the module to make the settings take effect.
  2. Enable the serial function. The serial port of RPi is set to serial terminal debugging function mode by default. If you want the serial port services as a common IO, you should modify the settings on the RPi. When the terminal debugging function is disabled, you cannot access RPi board via the serial port any more. If you want to control the RPi, you may need to enable the debugging function of the serial port again.
    sudo raspi-config
    Select Advanced Options -> Serial. Select the option no can disable the serial debugging function. And then, the serial port can be used for serial communication. And select the option yes can enable the serial debugging function. You should reboot the module to make the settings take effect.
Note: the serial port on Raspberry Pi 3 Model B is unusable, because Pin 14 and Pin 15 is connected to the on-board Bluetooth model.
  1. Start up the spi function, run the following command:
    sudo raspi-config
    Select Advanced Options -> I2C -> yes, to start up I2C core driver.

FAQ

Question:
It didn't come with a battery, why?
Answer:
Due to shipping reasons, this product doesn't come with any batteries. You shall place a CR1220 button battery into the socket for clocking usage.
