Assuming the RTC of the Artemis Open log has been synchronized to GPS when the board is first powered up, then GPS board is disabled, then using pin 11 as a trigger input to the open log board applying a 2 Volt rising edge, what is maximum permitted trigger rate that the Artemis Open log can trigger and time stamp date and time.
Hopping the trigger input can cope with a trigger rate of several hundred Hz ?
Assuming all onboard sensors are disabled, serial logging is disable, analog logging is disabled and I only wish to record the absolute date and time when pin 11 is triggered by a rising edge.
Not sure what the timing drift is on the RTC but if the board is powered by an external battery figured the RTC should remain precise for a long time as long as the battery is topped up from a USB charger.
Thanks.
