Hello again all,
I've almost got my GPS clock circuit completed and am thinking about adding another LED (in addition to my solid power LED) to indicate the pulse signal.
I am using a Garmin 18x LVC GPS which uses a PPS wire connected to the DCD pin of my serial port. This generates a very accurate pulse at 1Hz (every second) and I am just curious if wiring an LED in parallel to this would cause any additional latency or other problems? Basically I feed the GPS 5V of power and it transmits/receives to/from a serial port connector. The PPS wire is an additional wire coming from the GPS that generates a pulse to the DCD pin.
Any advice would be appreciated!
