SPI display interface.

on this struct and all implementation hace a problem, 
do you have this
pub struct SPIInterface<SPI, DC> {
    spi: SPI,
    dc: DC,
}

should be like this

pub struct SPIInterface<SPI, DC, CS> {
    spi: SPI,
    dc: DC,
    cs: CS
}

and all implementations should have "CS"  

i have a problem in my connection with ili9341 and rp-pico
