red-button-trigger-timestamp 🔘 for Raspberry Pi Pico

This device allows using a Raspberry Pi Pico board to capture accurate timing information at the time an external trigger fired. We use it with FLO to log when exactly our high speed cameras were triggered.

Directories:

• firmware - source code for the firmware to be flashed on the Raspberry Pi Pico
• red-button-trigger-timestamp - source code for the command-line program running on a host PC which talks to the Pico and writes a .csv file with the trigger timestamps
• red-button-trigger-timestamp-comms - source code defining messages types passed between the Pico and the host PC
• hardware - schematic and 3d-printed enclosure
