Indeed it's in RGBHV that I get an image. But shouldn't it at least be something coming out of the VGA out, even if the input isn't recognized?keremimo wrote:Stremon: Just to understand how your switch works, do you get an image when you set the stock firmware on RGBHV mode? That one is not completely implemented yet.
Also, looking at your NodeMCU, it seems that you have not powered it yet? It needs power as well. Connect it to USB or use VIN input & a ground with 5v.
I mean when I switch the stock GBS on, even without input I go a video out signal. With GBS control I got no video signal at all, whatever profile I try loading.
For the NodeMCU, I saw in the tutorial it could be powered in 3.3V by the GBS VCC and GND, which I did (the red and black cable in my picture), but maybe I didn't plug into the correct pins?
The NodeMCU powers on fine and I can access the web interface.
I tried with a powered USB cable as you suggested, but it doesn't change a thing.
