Pico Software Problem with digitalPulse

Thank you for the prompt reply.

It was confusing to me, having just received the Pico, about what procedure worked and what didn't work, about unplugging, "cannot communicate," using reset(), starting over, and so on. Maybe a sentence or so somewhere early in the process would be helpful. I did forum and Google searches on the Web IDE error "cannot communicate" (or whatever the exact message was), but never found anything. I just stumbled around until figuring it out.

I am using Windows, and the Pico shows up as (only) COM24, which surprised me, as I am up into COM90+ with all the toys I have (many versions of Arduino, Raspberry Pi, MBED, PIC and so on).

The tutorial with the flash function that didn't work was the Chrome app Web IDE one. The IDE tutorial is a pain sometimes, since it is interactive only, so when anything goes wrong, like a typo, it seemed like I had to start over from step one. I'll try it again once I clean things up.

I did reset() and stopping the web IDE and stopping PuTTY several times and then trying things again, and digitalPulse was the only function that didn't work, no matter what. The IDE tutorial is a pain sometimes as when anything goes wrong, like a typo, it seemed like I had to start over from step one.

I'll try again to make everything as clean as possible and try the Pico Buttons tutorial once more.

Thanks also for deleting the github post, since that was the "contact us" link which I found at the bottom of the Pico Buttons tutorial, and then later thought the forum might be more appropriate.

I assumed there were some differences among the original Esprunio board and the Pico, as well as the Pico v1.3 and v1.4 versions, and perhaps the latest firmware, that might account for the problems I was having.

Thank you again for your help.
