You could do with exploring the Help -> Wiki -> Components search
Then ensure you have set the component properties.
For example, for the TimedInterval component you need to set a callback macro (that runs at the timed interval)

1) Help -> Library Updates
2) Add a Timer component macro to your project


Note: Timer component is not needed for simple Delay icon.

Try this C code
It might need to be placed after a Switch Read macro, which will initialise the pin for input.

Yes, that's correct

Ah, well done.

As there are a number of internal clocks, everything relates to the input clock frequency (internal, or external crystal)
So it's the input clock frequency that is limited to 26Mhz (and is set in the project options clock speed)

Have you set the clock speed in project settings, to the frequency of the external crystal?
Just checking
Otherwise, could you post an example project?

I think the array gets filled with the received in data.
But I can't check the component just now.

As chipfryer27 says, I would suspect the issues are due to weak received signal strength. Time reception does not require sight of multiple satellites, position does. Can you run the setup outside, or near a window?

output of the Tx terminal of the pic within Proteus, activity is seen but what the virtual terminal reads does not correspond to the values ​​that Flowcode is sending.

A baud rate issue?
Is the PIC clock setup ok?

Use the Flowcode Interrupt icon
Add it once at the start of your main program.
It has properties where you set the input pin to be used, and the macro to call when the interrupt occurs.
