Re: Viable Options To Simplify the Custom Firmware Build Process

you can use a script like I do in my project: https://github.com/kevinkk525/pysmartno ... ository.sh
(there are also some board definitions and sync scripts. So I just need to execute the build script and it syncs my project files and builds the firmware).

Thanks for pointing this out. Sometimes you can't see the forest from the trees...
Indeed and that can take half a day. So always good to ask, saves a lot of time. Similar things happened to me too :D

Re: Can't freeze __init.py__

Simple oversight but "__init.py__" is a wrong file name. It should be "__init__.py"

Re: Anyone have some sample code for UART or SPI, communication between two boards?

In my unfinished project for providing wlan to a rpi pico I'm using a UART communication with CRC verification of the messages. The project might be unfinished but the uart communication is completed and works. But since you're new, I don't know your level of programming experience, so maybe just ta...

Re: ESP8266 Stromversorgung für LED WS2812E mit WLED

So ist es. Kabel von Netzteil zu LEDs sollte dick genug sein und kein mini Steckboard Kabel.

Re: ESP8266 Stromversorgung für LED WS2812E mit WLED

1. Der Spannungswandler auf dem ESP8266 board kann keine 20W liefern (vllt 5W höchstens?) und ein normales USB Netzteil auch nicht. Ich hatte mich auch gewundert, wie gut die LEDs im Test am PC geleuchtet haben aber die brauchen deutlich mehr Leistung. 2. Der Vin-Pin auf den meisten NodeMCU esp8266 ...

Re: ESP8266 Stromversorgung für LED WS2812E mit WLED

Yes you need an external power source, the esp8266 can't provide 20W and neither can your USB power source. I'm using a 5V 8A power source (https://www.amazon.de/gp/product/B00MWQF08C) for my esp8266 and Neopixel type LED stripes with 288 LEDs. You just connect the Vin pin of the esp8266 board (so t...

Re: Wifi bridge for RPI Pico

My project is currently "paused" because I have too much going on.. The Airlift project sounded great but I could never get it to work with micropython. I wrote a basic wrapper based on the circuitpython project and could communicate with the Airlift and connect to a wifi but any attempt to create a...

Re: Increase ROM size

yes, the bigger the firmware the smaller the VFS. But I don't need a big VFS, just a few simple config files.
