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.

Trying new version 6 firmware on my old RP2040.

Now I'm confused.

Using the MANUAL example:


SETPIN GP21, DOUT
DO
PIN(GP21) = 1
PAUSE 300
PIN(GP21) = 0
PAUSE 300
LOOP


I get blinking on GPIO pin 16


Using this code:



SETPIN GP16, DOUT

DO
 PIN(16) = 1
 PAUSE 100
 PIN(16) = 0
 PAUSE 100
LOOP


I get fast blinking on pin 12.

???

Pin(16) is GP12. You must use either the pin numbers or the GP numbers--they aren't the same.
