Re: Unreliable GPIO

It may benefit to recap your problem & results. It is then easier to review/support. I think that you state; (1) that you are running a tight loop collecting GPIO readings, (2) you sample on a single core running in IRAM but yet you see close to 1uS 'wobble' in the readings (depending on which other...

Re: Django/ESP32

Would you clarify.... You need a django api running on the ESP? Would not any RESTful api on the ESP work? Why not? Do you really mean that you want to access a django api from the ESP? There is nothing special about django from the Ethernet view. Its all HTTP presented in a nice RESTful way. As you...

Re: expose ESP32 WebServer to public without router setup or third party service

Is it possible to do this without setting up the router from a third party device? You would have to run this software from a server and have your local device register with the server. End users would do the same. The server address would be the public point of access because you cannot change you...

Re: expose ESP32 WebServer to public without router setup or third party service

The esp32 should be capable of getting the publicIP of the router isn't it? Typically yes, if you know the router's API. Most routers have a page displaying public IP and some provide that data in an easy to use API. now it would just have to tell the router to forward posts that are coming onto th...

Re: expose ESP32 WebServer to public without router setup or third party service

Never say never but not possible without router access and/or you have the uplink. How is an external client going to address you when all you have is a 'local' class C address? You need port forwarding or a 'less local' IP address (direct, remove the router) to be found. Now maybe you could do some...

Re: Best sensor for detecting crossing a line [COVID]

Ok, understand.
IR is going to be better as Sprite says.
Saturation and reflection can be issues but Sprite's explains some simple mechanical solutions to avoid i.e. tube & filter.
Just thinking; pizo floor tiles? Not sure how that might be better but wonder....

Re: wearleveling filesystem image uploading

Understood. I'm empty then. As you are no doubt aware the problem will be 'sharing' format information between a PC upload program & the ESP drivers. IJDK what that format is. Hence TFTP or SPIFFS updload gets round the format issue. The host side tool approach does seem to expose you to version cha...

Re: Best sensor for detecting crossing a line [COVID]

PS You need to think the use cases through. Someone walks up to the entrance. The IR sensor 'senses' them. They hover, they go back for the kids who (as always) are messing around. Then back through. How many entry/transactions is that? Let alone the dad carrtying junior in (who then runs back to .....

Re: Best sensor for detecting crossing a line [COVID]

Gonna have to dis 'Click-wirl'. Instead we need a GPP (“Genuine People Personality”) for the turnstyle.
The turnstile could indeed then have a satisfied sigh-like quality to it. “Hummmmmmmyummmmmmm ah!”

Re: wearleveling filesystem image uploading

I preferably want the filesystem to be ready when programmed You can still do that, well with a small boot action addition to your main application. As I understand it you simply lack the ability to directly place a FatFS image into FLASH whilst preserving wear levelling details. You can however pr...
