About The Project

This project is a simple StopWatch for measuring times on different processes or activities. The project was chosen to test some 4-layers PCBs and experiment with both the XLP (Extreme Low-Power Technology) and the pic18LF14k50 itself. You can measure from milliseconds to more than 99h.

The PCB does not have any power button, since the project's approach is to use the XLP technology of the PIC. It only has two buttons: start/mode button and pause/stop button.

Build one

1. Get the gerber files for the latest version: V1
2. Send them to a PCB manufacturer (Our Sponsor is PCBWAY)
3. Buy all the components from the Bill Of Materials
4. Solder everything with the help of the schematic
5. Burn the latest firmware
6. Give us a Star to the respository ;)

Here it is an assembly video:

Usage

Instructions of use:

• Pressing "Start" will start the StopWatch.
• Pressing "Pause" will stop the StopWatch.
• Long press "Start" : it will change the display mode.
• Long press "Stop" : It will reset the time to 0.
• 60s without pressing any button: Save Energy Mode -> Display off. It will still count the time.
• 10s without pressing any button in pause mode: Deep Sleep Mode -> Display off. Not counting

Roadmap

• Stopwatch and show it on screen
• enable/disable sound when pressing buttons
• Low Power Consumption
  • Lower the frequency of the microcontroller at minimum
  • Enter deep sleep mode automatically
  • Save energy mode while still working: Display off
• Measure power consumption

See the open issues for a full list of proposed features (and known issues).

State: Project FINISHED - 18/08/2022
