OpenIMU330BI 1PPS usage

OpenIMU330BI. When Sync signal from external device with 1PPS from GNSS module, How long does it take to initalize the sync?

Hi PineTreeWild,
It will take less than 10s to finish the sync with 1PPS in the begining.
The sync process is that:

  • CPU detects sync pulse and measures it’s period with sub-microsecond precision

  • If period is within 0.01% of target value for few consecutive periods signal considered to be valid and system will sync to it.
