Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Forum Index : Microcontroller and PC projects : SetPin interrupt - won’t let me set it...

It must be too late.

SETPIN D8,7,RESET 'RESET interrupt input pin(pull low to trip)

MMBasic rejects it saying invalid configuration.

Manual page 34 says that syntax is SETPIN pin, cfg, target.

  Quote  7 Interrupt on high to low input (pins 1 to 20, D0 to D8)

‘target' is the interrupt routine which can be a line number,label or user
defined subroutine.


At first I thought that 'RESET' might have been a reserved word, so tried something like REE, but that was rejected also for the same reason.

What am I doing wrong?

Time for bed anyway, and my brain can't work it out when I am tired... Edited by Grogster 2014-02-28

Is this on the Colour Maximite?

D8 is only valid on the Arduino connector of the CMM.

Does it work if you the pin number.
D8 = 29

"You can use the labels D0, D1, etc in the SETPIN and PIN statements or you can use their corresponding
numbers (D0 = 21, D1 = 22, etc and A0 = 35, A1 = 36, etc)."

Ah, found it. It is a bug in the documentation - interrupts can only be set on the first eight digital pins on the Arduino connector and they are D0 to D7 (not D8).

Can you move your move your input to D7?

Yes, I can move the reset switch to D7 no problems at all - thanks.
