Fun with ESP.
I had decided - because I wanted to try some special software that exists for the ESP32 - to buy a development board. In the past I often heard the name "NodeMCU" and thought, yes, then it should be a NodeMCU.
On Amazon I also found an offer - where a free eBook was supposed to be included.
German seller... everything good?
Haha.
- The eBook turned out to be three single PDFs with the schematic, the pin assignment and an advertising text for the module "Wroom-32".
- The schematic shows a LED which is not built in at all. Probably more is wrong with it and it belongs to a completely different board. Found out after trying multiple pins in a blink-sketch. - would have been easier and better for my poor finger if the following had worked:
- Installing the software for Arduino was surprisingly easy. Not uploading. It worked ONLY when you push the button every f***ing time.
After a lot of surfing and finding 25 wrong solutions on the www(every single one didn't work), with studying the maybe wrong schematic and experimenting I found a solution on my own (had to add 10uF on EN and GND, and 1kOHM between GPIO0 and GND).
Uploading takes ages compared to Teensy.
When beginners are confronted with such cr*p, all they can really do is give up.
It's taken me 2 hours to do/find out all this - before I can even start
I'm sure I will install the thing I want to see, see how it works, do only minimal things and then put it faar away...
..and to be "on topic" again, I'll try to do it with Teensy
