Typical power problems arise because ESP32 current consumption can rise to about 0.5A which can cause voltage drops in USB leads. Another cause are lousy wall-warts designed for phone charging rather than continuous running. (To anyone reading this post :D ): Are there any specific USB cables and/o...

Yes, this would be good to support. It's not a small piece of work but definitely do-able. See https://github.com/micropython/micropython/issues/8927 if you're interested.

Great. Thanks jimmo.

Google brought me here. This would be great. Just +1'ing this.

I have a similar query. Trying to run some networking / project code on core 0 and a web server (microdot) on the other core (w/no need for any sort of shared data)

I think I confused 2 different topics. In short I thought the webrepl was linked using / broadcast an SSID. I stumbled on to https://www.srccodes.com/setup-web-repl-esp8266-12e-connect-micro-python-prompt-repl-wifi-access-point-ap-hello-world/ import network; ap = network.WLAN(network.AP_IF); ap.act...

I think I am making a mistake. Picoweb does not seem to work with Micropython I understand that it _is_ possible to make it work with regular MicroPtyhon, but the hassle probably isn't worth it. I'd suggest trying any of the other HTTP server libraries. microdot (https://github.com/miguelgrinberg/m...

@modulusmath, Could you share how you got MicroPython working on an ESP01? I have been trying to get it working as well, but I can't seem to get to the REPL at all after what I believe is successful flash? Here is what I have tried: # esptool.py --chip esp8266 --port /dev/ttyUSB0 flash_id # esptool...

Hi All. I have a few of the AI-thinker style ESP32-CAM-MB's and pulled off the little -MB/connecter to put the cam on a breadboard. However, I can't get either of the cams to broadcast their SSID. The webrepl_setup runs fine w/o any errors but but cannot see the default SSID starting with "MicroPyth...

I wrote a clock app for the ESP32 where I messed with time. I got the NTP time and then offset it by timezone. Here's how I set the localtime: # Set the RTC to local time. (I don't think the uP docs are exactly right about this.) RTC().datetime((yy, mo, dd, 0, hh, mm, ss, 0)) You can see all of the...

Depending on what you're doing, might be tough to beat https://www.makerfabs.com/makepython-esp32-color-lcd.html w/the wrover option. It's $14.99 + shipping (at least in the US). Clearly significantly more costly than esp8266 but I overcame my ram issues w/it. Color oled as well. I am fiddling w/usi...

I can still write to the OLED and access the 'net. Am I close or is it like I'm way off? I honestly believe there aren't enough pins on an ESP-01 to do this. How about rendering the OLED display in inverse video if it's over your warning temperature? It's kind of a big LED, after all ... Actually, ...
