ESP-WROOM-32 set watch

[HummerDK]

Hi

I can't seem to get setWatch() to work on my ESP-Wroom-32 board. I have tried many differents pins, but all of them gives me the following warning:

WARNING: Unable to set watch. You may already have a watch on a pin with the same num, or this pin cannot be used with watch

I have tried both with and without clearWatch(); :
clearWatch(); setWatch(function(e) { console.log(e.time-e.lastTime); }, D18, {repeat:true, edge:'falling' });

Am i doing something wrong here?

Which firmware version are you using? I know a few tutorials out there seem to suggest using firmware that's now several years old and that does have issues.

I installed 2v26 through the online flasher

I have now tried two different esp-wroom-32, used the WEB-IDE and VSCode. Same result on all combinations

Flashed to version 2v25 and it now works

Ok, thanks for letting me know. I just tracked this down to this PR: espruino/Espruino#2608

ESP32 - fix jshCanWatch for ESP32 & ESP32S3 - which seems to have had the opposite effect - basically disabling watches on all the pins where it made sense.

I've just changed it for cutting edge builds (and 2v27 when released), so only pins 6..12 (SPI flash) are now disabled
