Remote sensing of GoPro from its blinking LED?

In post 1, the GOTO MAINLOOP is in the wrong place. Move it to before the "recording" label.

It may still not do what you're looking for, but fix that for sure.

I don't understand your logic. Would you mind giving me more information?

Here's what you have now (I removed some of the code for clarity)

Mainloop:
if CYCLE = 0 then goto Mainloop ' just loop
if cycle = 1 then gosub recording ' call the subroutine and then return to the next statement

' after executing the above for cycle= 1 you'll return here
' the next statement is the beginning of the "recording" subroutine
' it'll execute that, hit the 'return' and cause a problem since there was no matching call 

Recording:
' do stuff
return

' you'll never get here
goto mainloop

Without changing any of the code to test 'cycle', here's what it should look like

Mainloop:
if CYCLE = 0 then goto Mainloop ' just loop
if cycle = 1 then gosub recording ' call the subroutine and then return to the next statement

goto mainloop     ' infinite loop back to main 

Recording:
' do stuff
return
