I understood that the esp8266 gpio boot modes truth table was as follows:
.............which seems to imply that holding gpio2 low during boot is not an issue. This however is not my experience and I read herein that posters to this site share my experience and warn against the practice.
I only have a few esp01 modules to play with just now so don't have access to other gpio ports (unless I get into some microscopic soldering fun which frankly my eyes are just no longer up to). I am trying to monitor a door switch which could be in either position at esp startup so I can't assume or rely on a particular startup state.
I read an instructables article that advises one to use the two gpio's 0 and 2 in tag team with one an input and the other an active low output to get around the problem.
Does EPS Easy support this trick and if so, how do I implement it?The trick is to not connect the external switch directly from the GPIO0 or GPIO2 to GND but to connect it instead to another GPIO pin which is driven to ground (as an output) only after the ESP8266 starts up.
Thanks,
