DHT22 driver has stopped working in master

Post by larsks » Fri Oct 12, 2018 2:35 am

I noticed that with recent esp8266 micropython builds I was no longer able to interact with my DHT22 temperature sensors. I spent some quality time with git bisect this evening and logged https://github.com/micropython/micropython/issues/4233. I have a workaround (revert the commit that introduced the problem), but I'm hoping that someone more familiar with the esp8266 port can take a look at this and help figure out what's going on and what might be the correct solution.
