GPS Bricklet 2.0 PPS signal

[Jonni]

Hi!

 

I'm wondering if the GPS Bricklet 2.0 only receives PPS signal, or is it possible to make it output PPS signal as well? When reading the firefly x1 documentation it seems like it should be possible to output PPS signal. 

 

Thank you

You can get the PPS signal as a callback in the API. From your question i assume you want it as a digital output?

 

What is can do is: Use a GPS Bricklet 2.0 and a Industrial Digital Out Bricklet and every time you get the callback you set a digital output on the Bricklet. This will of course have a jitter that depends on the USB stack of your PC. I would expect something around +-1ms.

Thank you so much, borg! 

 

Correct, I want it as a digital output. In addition, I would like to transmit an RS-232 NMEA $GPRMC sentence/message following the PPS signal. How would you proceed to do this?

 

Again, thanks!

You would need to add a RS232 Bricklet and construct this sentence from the data you get from the GPS Bricklet.

 

The GPS Bricklet does not have API that transfers the NMEA sentences to the PC.
