I'm using the new Raspi 4 4GB wiht a Picam V2.
My code ist listed below. This code works brilliantly with my Raspi 3, but not anymore with the Raspi 4.
I don't get any Errors or exceptions. Although the "capture" works great.
Code: Select all
import time from picamera import PiCamera camera = PiCamera() camera.start_preview() sleep(5) camera.capture('/home/pi/Desktop/image.jpg') camera.stop_preview()
And here is the Problem.
The preview is not shown.
I want to show the preview on a Touchscreen with a DVI-Port.
So I connected the Touchscreen with a HDMI-MicroHDMI-Adapter and a DVI-HDMI-Cable.
Can anyone say where I lose the Signal?
Thanks for your help!
