Hi there, I hope I'm the right place to ask this question ;) I'm trying to connect a touchscreen (kind of cheap waveshare 3.5)with 2 SPI channel to my nanopi Neo. Both tft and touch (ADS7846) are using a common SPI bus with different CS.
I'm running out of idea, I cannot find a simple and nice distribution with a clean documentation to do that. On some distribution like DietPi or Debian Jessie I modified the Fex file to try to integrate another CS. I tried to integrate some DT on DietPi, but seems not to be effective. So I end up with the conclusion that the HW spi support only one CS (CS0) and I need to find a solution to connect a software GPIO for CS1. On fex file for instance I found manual_cs that is not supported yet. Some gpio_cs libraries seems to exist but I don't know where to begin. Does somebody already try to add this kind of new chip select to an existing HW bus? If not would you have an idea where you can redirect me (forum or other) that could help me to find the solution? Thanks a lot guys! -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
