A small Python script that runs on a Raspberry Pico W. This project utilises a MAX7219 8 digit, 7 segment display to display a NTP stream output of the current time, collected from an NTP time server.
This relies on the CPU to maintain accurate time-keeping, which does not have a RTC. To account for this, the device will repoll the NTP server every 15 minutes.
Configuration is done via a JSON file. An example file is found in the repository with configuration needs specified.
Copy the .py files to the root of the Raspberry Pi Pico, when in MicroPython mode and connected using Thonny, or another way to access the ttyACM0.
This depends on:
