Allow use of DataSize of 16 bits
I'm trying to use this library for an embeded project with an LCD that uses an SPI with 16 bits of data as DataSize. I can create the SPI correctly width let spi = Spi::<_, _, 16>::new(pac.SPI1); (note the 16 there) but then I get some issues because it doesn't implement write 8 like this library requires.
I don't think there's a way to allow 16 bit datasize currently so this would be an extension, I can play with hacking away at an implementation but I don't think I can do it neatly without a bunch of code duplication.
The main reason why there's no 16bit interface is that I haven't come across a display which supports 16bit data. Would you mind pointing me to the datasheet for your LCD?
I'm using the ILI9488 but the drivers for St7789 also work, I think. I've in the meanwhile found that it may support 8bit also, on page 69, but haven't tested it yet.
I'm using the Mipidsi crate as the driver
As far as I know those displays exclusively support 8bit (and sometimes 9bit) word size on SPI, hence my question. I checked the data sheet you pointed to but I couldn't find any mentioning of a 16bit word size for SPI. If you look at 4.2.1 in the ILI9488 datasheet you can see that the 3-wire mode uses 9bit word size and the 4-wire mode uses 8bit word size.
Much time has passed so I doubt this is helpful @marco-silva0000 :
I didn't realise that I could have been using Mipidsi crate so I ended up making https://github.com/tommy-gilligan/ili9488-rs (based on https://github.com/yuri91/ili9341-rs). I'm not sure if I'm using display-interface correctly but maybe it's a moot point because I'll try to use Mipidsi now. Thank you for the comment for helping me figure out the right thing to be using!
