Each digital I/O pin has 8 different modes that can be selected, including GPIO.
:::note In GPIO mode, each digital I/O can produce interrupts. :::
:::note Up to 8 digital I/O pins can be configured with pulse-width modulators (PWM) to produce signals to control motors or create pseudo analog voltage levels, without taking up any extra CPU cycles. :::
:::note Make sure you don't input more than 1.8V to the analog input pins. This is a single 12-bit analog-to-digital converter with 8 channels, 7 of which are made available on the headers. :::
:::note There is a dedicated header for getting to the UART0 pins and connecting a debug cable. Five additional serial ports are brought to the expansion headers, but one of them only has a single direction brought to the headers. :::
:::note The first I2C bus is utilized for reading EEPROMS on cape add-on boards and can't be used for other digital I/O operations without interfering with that function, but you can still use it to add other I2C devices at available addresses. The second I2C bus is available for you to configure and use. :::
:::note For shifting out data fast, you might consider using one of the SPI ports. :::
:::note This chapter is writing under Win10. The steps are familiar for the other operate systems. :::
Use the provided micro USB cable to plug your Seeed Studio BeagleBone® Green Wireless into your computer. This will both power the board and provide a development interface. Seeed Studio BeagleBone® Green Wireless will boot Linux from the on-board 2GB or 4GB eMMC.
Seeed Studio BeagleBone® Green Wireless will operate as a flash drive providing you with a local copy of the documentation and drivers. Note that this interface may not be used to re-configure the microSD card with a new image, but may be used to update the boot parameters using the uEnv.txt file.
You’ll see the PWR LED lit steadily. Within 10 seconds, you should see the other LEDs blinking in their default configurations.
- D2 is configured at boot to blink in a heartbeat pattern
- D3 is configured at boot to light during microSD card accesses
- D4 is configured at boot to light during CPU activity
- D5 is configured at boot to light during eMMC accesses
Install the drivers for your operating system to give you network-over-USB access to your Beagle. Additional drivers give you serial access to your board.
| Operating System | USB Drivers | Comments |
|---|---|---|
| Windows (64-bit) | 64-bit installer | |
| Windows (32-bit) | 32-bit installer | |
| Mac OS X | Network Serial | Install both sets of drivers. |
| Linux | mkudevrule.sh | Driver installation isn't required, but you might find a few udev rules helpful. |
:::note For window system, please note that:
- Windows Driver Certification warning may pop up two or three times. Click "Ignore", "Install" or "Run"
- To check if you're running 32 or 64-bit Windows see this.
- On systems without the latest service release, you may get an error (0xc000007b). In that case, please install and retry:
- You may need to reboot Windows.
- These drivers have been tested to work up to Windows 10 :::
Using either Chrome or Firefox (Internet Explorer will NOT work), browse to the web server running on your board. It will load a presentation showing you the capabilities of the board. Use the arrow keys on your keyboard to navigate the presentation.
Click http://192.168.7.2 to launch to your Seeed Studio BeagleBone® Green Wireless. Older software images require you to EJECT the BeagleBone® drive to start the network. With the latest software image, that step is no longer required.
To begin editing programs that live on your board, you can use the Cloud9 IDE by click
Using your smart phone or computer to scan local Wi-Fi network and connect to the AP named "BeagleBone® XXX"
After connection succeeded, it will head to the login page automatically. Select the SSID of your Wi-Fi and enter the passwd, click OK.
Now your Seeed Studio BeagleBone® Green Wireless is connected to Wi-Fi.
Connect to Cloud9 IDE and start a new terminal. Start the bluetooth config with the command:
bb-wl18xx-bluetooth
bluetoothctl
Type scan on to scan local bluetooth devices. My device named "jy" is found.
Copy the device mac address, then contect to the device with the command:
pair 0C:xx:xx:xx:xx:0B
trust 0C:xx:xx:xx:xx:0B
connect 0C:xx:xx:xx:xx:0B
Now your Seeed Studio BeagleBone® Green Wireless is connected to your bluetooth device. Type quit back to the terminal.
Play music on Seeed Studio BeagleBone® Green Wireless, then you will hear music on your bluetooth speaker device.
You need to update the board to latest software to keep a better performance, here we will show you how to make it step by step.
First of all, you have to download the suitable image here.
:::note Due to sizing necessities, this download may take about 30 minutes or more. :::
The file you download will have an .img.xz extension. This is a compressed sector-by-sector image of the SD card.
Download and install 7-zip.
:::note Choose a version that suitable for your system. :::
Use 7-zip to decompress the SD card .img file
Download and install Image Writer for Windows. Be sure to download the binary distribution.
You need a SD adapter to connect your microSD card to your computer at the first. Then use the software Image Write for Windows to write the decompressed image to your SD card.
Click on Write button, then the process is started.
:::note
- You may see a warning about damaging your device. This is fine to accept as long as you are pointing to your SD card for writing.
- You should not have your BeagleBone® connected to your computer at this time.
- This process may need up to 10 minutes. :::
Insert SD card into your (powered-down first) board. Then the board will boot from the SD card.
:::note If you don't need to write the image to your on-board eMMC, you don't need to read the last of this chapter. Otherwise pleas go ahead. :::
If you desire to write the image to your on-board eMMC, you need to launch to the board, and modify a file.
In /boot/uEnv.txt:
##enable Generic eMMC Flasher:
##make sure, these tools are installed: dosfstools rsync
#cmdline=init=/opt/scripts/tools/eMMC/init-eMMC-flasher-v3.sh
Change to:
##enable Generic eMMC Flasher:
##make sure, these tools are installed: dosfstools rsync
cmdline=init=/opt/scripts/tools/eMMC/init-eMMC-flasher-v3.sh
Then you will find the 4 user led light as below:
:::note If you don't find the upper tracing light, please power down and power up the board. :::
When the flashing is complete, all 4 USRx LEDs will be off. The latest Debian flasher images automatically power down the board upon completion. This can take up to 10 minutes. Power-down your board, remove the SD card and apply power again to be complete.
We have provided Mraa library and UPM library to make it easy for developers and sensor manufacturers to map their sensors & actuators on top of supported hardware and to allow control of low level communication protocol by high level languages & constructs.
Mraa is a C/C++ library with bindings to Python, Javascript and Java to interface with the I/O on Seeed Studio BeagleBone® Green, Seeed Studio BeagleBone® Green Wireless and other platforms, with a structured and sane API where port names/numbering matches the board that you are on. Use of Mraa does not tie you to specific hardware with board detection done at runtime you can create portable code that will work across the supported platforms. UPM is a high level repository for sensors that use MRAA. Each sensor links to MRAA and are not meant to be interlinked although some groups of sensors may be. Each sensor contains a header which allows to interface with it. Typically a sensor is represented as a class and instantiated.The constructor is expected to initialise the sensor and parameters may be used to provide identification/pin location on the board.
Mraa and UPM are already installed in the system image of Seeed Studio BeagleBone® Green Wireless, so you don't need to install it. However if you want to update the library, or want to upgrade the library, use apt-get update and apt-get upgrade please. Refer to https://github.com/intel-iot-devkit/mraa and https://github.com/intel-iot-devkit/upm for more information.

Grove is a modular, standardized connecter prototyping system. Grove takes a building block approach to assembling electronics. Compared to the jumper or solder based system, it is easier to connect, experiment and build and simplifies the learning system, but not to the point where it becomes dumbed down. Some of the other prototype systems out there takes the level down to building blocks. Good stuff to be learned that way, but the Grove system allows you to build real systems. It requires some learning and expertise to hook things up.
Below listed the Grove modules that work well with Seeed Studio BeagleBone® Green.
