Waveshare 1.54 V2 does not work

[agmes4]

Problem

I tried using this lib for the waveshare 1.54 V2 this did not work

Things I noticed

After some trying I noticed that when ever writing data image in 4 Pin mode the chip select is pulled to high every time a byte was written to the bus. When trying an other Arduino sketch it worked. The only change I noticed on the Bus was that it did not pull the CS to high when ever a byte of the image was written.
