Raspberry Pi and Mesa 7i90 SPI works well

Ok, due to the great demand I will give some additional infos.

SPI cable between raspi3 and 7i90 (max length 20 cm wo differential driver):

Code:

Raspi3 40 pin header: 7i90 26 pin header: ===================== =================== 19 - MOSI -------------------------> 13 - SPIIN 21 - MISO <------------------------- 15 - SPIOUT 23 - SCLK -------------------------> 11 - SPICLK 24 - /CS -------------------------> 17 - /SPICS 20 \ 25 - GND <------------------------> 10, 12, 14 - GND 30 /

But not too much, because I'm following the open source tradition, information is a "debt to be collected" ...


Have fun!
