There is a problum with GPIO19 for micropython #7

Closed CaptainJackey closed 3 years ago

CaptainJackey commented 3 years ago

It can't control high or low with machine.Pin with GIOP19, no higt or low output, but 18, 20 is OK! please cheak!

Test code as follow:

from machine import Pin import time

LED1 = Pin(18, Pin.OUT)

LED1.high() time.sleep_ms(1000) LED1.low() time.sleep_ms(1000)

Duplicate of https://github.com/raspberrypi/pico-sdk/issues/28 which is fixed by https://github.com/raspberrypi/pico-sdk/pull/31 , so this should hopefully be fixed in the next release of MicroPython.

So when will the official website UF2 File will be updated? https://www.raspberrypi.org/documentation/pico/getting-started/

As soon as possible after the fix has propagated through the repos and all the PRs resolve themselves. We're expecting to do a new SDK release shortly which should resolve the issue. I can then build a new MicroPytyhon binary.

Looks like the PR just got merged into MicroPython mainline,https://github.com/micropython/micropython/pull/6791#issuecomment-769832231. Not sure that includes the fix though.

Not sure that includes the fix though.

It doesn't include it. We are using the master branch of pico-sdk which doesn't yet have the GPIO19 fix.

@dpgeorge https://github.com/raspberrypi/pico-sdk/releases/tag/1.0.1 has just been pushed :slightly_smiling_face:

dpgeorge commented 3 years ago

This should now be fixed in MicroPython mainline, see https://github.com/micropython/micropython/pull/6826
