    Perform RT patch on the RPI -- 2 6 Tage left
    VERIFIZIERT

    RTLINUX research the linux RT patch for the Raspberry PI kernel (kernel version >=5 so not 4.19) and make a setup with a Raspberry PI proving that the Realtime Patch is necessary to achieve a timing goal. Can you guarantee that an RPI with or without load always responds within 1msec after detecting an event, even if it is 100% busy with other tasks at that time? Use public RT measurement tools to demonstrate that with the RT patch the system may or may not slow down (?) but can process a certain input with 100% certainty. Comparing Cyclictest results between RTLinux kernel and regular os kernel is enough. Compile and configure the kernel source code yourself and change the local "uname" to show your name when you do "uname -a". EXTERNAL INTERRUPT Use of external int...

    We have two energy meters supplying Modbus data. We want to capture the data from 6 data points : date, time, flow, temperature in, temperature out and electricity used and then provide a real time dashboard of information and energy calculations from the data. I would like this dashboard to be on a windows application but also allow the information to be supplied to a company wide Scada system. The information should have a feature to allow us to select the data from different time periods. eg daily, monthly annually as well as the real time information. The calculations will be simple formulas to allow the data analysis to be presented on the desktop. Outputs required on desktop: Time period Total flow Weighted average temperature in Maximum temperature out Temperature delta KW of en...

    The 4 Data input panels will have a UI with Keypad for data input. The data should be stored in an excel sheet/google sheets/ any other data representation method. As it is an industrial setup, we need keypads that will ensure rugged usage. None of these panels will be connected to any of the machines in the industry. We just need this for data tracking of our products. So the user will just input the production data and that data needs to be saved some format.

An Ultrasonic receiver is also placed on the front portion of the car operatively receiving a reflective Ultrasonic wave signal. The reflected wave (detected pulse) gives the distance between the obstacle and the vehicle. Then a microcontroller is used to control the speed of the vehicle based on the detection pulse information to push the brake pedal and apply brake to the car stupendously for safety purpose.
