My problem is that I cant get SPI1 and the LCD screen to work at the same time.

Only SPI1 with the spi1-1cs overlay worked and only the waveshare35a overlay working, I tried to make my own overlay and didn't worked, I don't even get the spydev1.0 to show up together with my LCD screen.

I have a Pi3 with Jessi and a Waveshare 3.5" LCD.

    What sort of LEDs? Why do they need to be connected via SPI? Why not use the auxiliary SPI device? – joan May 5 '19 at 9:09
  • WS2801 LEDs, and i need the spi to controll each LED individually, here is a link (german)(tutorials-raspberrypi.de/…) – Sven K May 5 '19 at 9:21

    For future reference APA102 based LED strips are much easier to control. They don't force you to use SPI or PWM/PCM hardware to drive them on the Pi. – joan May 5 '19 at 9:33
  • i must correct you, you need also a spi for the clock and a data line, so its pretty much the same, without spi you can't controll the LEDs individually. – Sven K May 5 '19 at 9:55
  • You do not need SPI to control an APA102 based LED strip. Any pair of GPIO can be used. – joan May 5 '19 at 10:23
