assert_example

Assert example code that can be used to print filename and line number where the assert condition was met

bbb_gpio_blinking_led

Example code that uses the Beaglebone Black platform to blink an LED using a GPIO as output

deadlock

Example code demonstrating how two threads depending on shared resources (mutexes) between each other can lead to a deadlock

func_mq_example

Example code for sending messages from one thread to another using a function call interface

imu_cam_strm

Software to interface the Beaglebone Black (BBB) with the MPU-6050 3 axis accelerometer and gyro IMU. Data is collected from the IMU over I2C bus in raw quaternion format, converted to Euler angles and then sent over the network to a remote machine. Also, software is provided to stream .jpg images from the USB webcam to a remote computer. Software is based on InvenSense Motion Driver Firmware examples found on I2CDevLib and ARMmbed

intvtimer

Example for setting up an interval timer on the Linux platform

mq_example

Example code for starting 2 POSIX threads and synchronizing their operation using a POSIX message_queue on the Beaglebone Black platform running Debian Linux

mutex_example

Example code for creating 2 Linux POSIX threads and synchronizing their execution using a mutex on the Beaglebone Black platform running Debian Linux.

pyclientserver-demo

This is an example for implementing server and client services using Python on a Linux platform

raspi-cam-record-stream

This package can be used to split stdin data stream to be written to a file (for storage) and also be output to stdout as well. It's used to get video data input from the Raspberry Pi NOIR camera and redirect the video data to a recorded data file and also STDOUT for online streaming using VLC.

seg_fault

state_machine_example

In this example code two POSIX Linux threads are created. The "CAM" thread implements a state machine that has knowledge of it's current status at any given time. The other thread operates the CAM thread services using its function call based message interface and cycles through the states in its state machine. The CAM state machine checks to see if an incoming command for state transition is received in a valid state. It will only transition its state if the transition event is received in the appropriate state.

threads

Example code for creating 2 Linux POSIX threads and controlling their run-time frequency on the Beaglebone Black platform running Debian Linux.

unity_mq_example

Example code for starting 2 threads and passing messages of different data types between them over a single message queue

usb_cam

Use linuxtv.org video grabber example using libv4l to capture images from a USB camera on the Beaglebone Black (BBB) running Debian Linux. Also, a small python script is provided to convert PPM images to JPG format
