Raspberry Pi Pico MicroPython Chapter 9
Chapter 9 is about building a Data Logger. I will be showing you the Pico's file system were we will be writing data to the pico's 2mb ram. To make the Data Logger a headless operation I will show you how to use main.py to automatically run the Data Logger program whenever the pico is powered up. To use the recorded data it must be downloaded to your computer to do this you must use Thonny's file transfer functions.
Note:
There was a problem following the chapter because every time the pico is powered, it overwrites the file, deleting all recorded values, so I demonstrate how to open files for appending.
