A miniature device that's keeping track of power outages.
- Raspberry Pi Pico
- Precision RTC Module (DS3231)
- Waveshare eink 3.7
The software is written in MicroPython 1.19.1
- Download the MicroPython UF2.
- Push and hold the BOOTSEL button and plug your Pico into the USB port of your computer. Release the BOOTSEL button after your Pico is connected.
- It will mount as a Mass Storage Device called RPI-RP2.
- Drag and drop the MicroPython UF2 file onto the RPI-RP2 volume.
To upload and configure your Pico Solar System you will need to install rshell. Make sure you have pip installed.
pip3 install rshell
- Download Pico Solar System
git clone https://github.com/dr-mod/blackout-logger.git
- Open the directory with the source code
cd blackout-logger
- Copy required python files to your pico
rshell
cp *.py /pyboard/
- Set time & configure the RTC module
repl
import time
import ds3231
rtc = ds3231.ds3231()
rtc.set_time(time.time())
To account for a timezone you might want to apply an offset to the UTC timestamp in seconds:
rtc.set_time(time.time() + 60 * 60 * (+ OFFSET_IN_HOURS) )
