Sample code for PB motor test rig
dashboard2.php is main display web page.
motor*.csv are data files. They are updated via the following python script
motor_stream2.py generates 100 new entries, one every 0.1 second.
The psuedo random data needs to be formated to more refect the actual value ranges. ( To Do!) Table 3 allows you to modify the first three parameter and simulates sending that out to the controller (file motor4.csv).
There is a test of phpchartlite (https://phpchart.com) to draw a graph of the incoming data stream. It would need more work plus upgrading to the full version to make a descent dashboard of the incoming stream.
Project is moving to node.js so no further upates to this php demo or POC.
Added Javascript version dashboard5.php, motor_stream3.py and scripted2.html for demo. it should create motor2.csv, but if not an updated one has been added. The screen will show an animated RPM dial for 100 cycles.
This code uses canvas_guages (https://canvas-gauges.com) and papaparse (https://www.papaparse.com) Javascript libraries.
Set up on a Raspberry Pi in the following directory structure:
