Microcontroller to CSV using both WebSerial (desktop) and Polyfill (Android-Chrome) to CSV
As of Feb 20th, 2023 Pol,yfill has a bug. I will try to fix it.
Note: For multiple values a timestamp needs to be the first value. If single multiple readings in each .csv file then a timestamp is not needed.
Headers are always needed.
This code collects data at a frequency of 50 Hz for 10 seconds collecting 500 samples, so things happen really fast
Save as time-series data
Save individual data in numbered CSV files for example try z-webSerial-single.html
