Re: Waveshare e-paper display how to rotate?

??? Sorry but, I really couldn't understand this thread. Rotating a frame buffer is as simple as (or I am missing something?): import framebuf def bufrotate(fb, w, h, defaultcolor=1): rotatebuf = bytearray(w * h // 8) rotatefb = framebuf.FrameBuffer(rotatebuf, h, w, framebuf.MONO_HLSB) for x in rang...

Re: WPA2 Enterprise

Up!

I would like to have an official answer is Enterprise WPK will be (ever) implemented. I think this feature is needed for serious IoT in enterprise environments.

Thank you

I will deliver firmware version in the next few weeks (I working on documentation), but the archived version in git has been working perfectly as a motion detection camera for several months, the firmware can be easily rebuilded...

Re: ESP32-CAM-MB + Development Board CH340G

Long time I am away from the forum, and I guess I missed a LOT! Said that I am having very hard time to get micropython and esp-32 camera working. Therefore I will have a look to your git repo, @remi_bertholet. Besides, I would like to recap what I achieved and especially what I DID NOT achieve (yet...

Re: Micropython docs - DHT

It happened the same to me. No way to make it working with DHT11.
I use the dht11 shield from WeMos and D1 mini.

Can somebody confirm latest firmware and library work properly?

Re: Copy lots of files in the mcus

I'd give a try to ampy: ls *.txt | xargs -n 1 ampy --port /dev/ttyUSB0 --baud 115200 put (assuming all your txt files are in one directory) adjust port and especially baud to have the most reliability OR (with bash): for f in `ls *.txt`; do ampy put $f ; done; OR with webrepl (assuming 192.168.1.100...

Re: Running out of memory w/ API requests

Just a look at your code. In 4 nested loops how many times the condition is satisfied and the array growths? To check the problem I would put a stub (just a print?) instead of filling the array. If the problem is the same, we have an issue with urequests, otherwise it should be investigated how many...

Re: LCD 1602 - Library

I have found this https://github.com/dhylands/python_lcd and looks pretty much what I was looking for.

Questions:
1. Did anybody make it working with WeMos D1 Mini?
2. Will it work in both i2c and GPIO modes?
