Raspberry Pi 2 and Spotpear lcd screen RRS feed

  • Question

  • I bought a Spotpear 3.5" lcd screen (http://www.spotpear.com/index.php/spotpear-raspberry-pi-lcd/spotpear-raspberry-pi-3-5-inch-lcd) . It connects with the GPIO connector and of course it only shows a white screen...

    With linux, it seems to require a special driver, is there anything equivalent for Windows?

  • I think there is no driver available at the moment. Please keep in mind that a 'windows driver' must not be compatible with Windows 10 IoT.

    Maybe other community members have a better solution / opinion. 

    Did you ask the vendor if it is IoT compatible? It would be nice to know. :)

  • Since this is an SPI device then you would be able use the SPI APIs to talk to the screen. There is a sample of just such code here: http://ms-iot.github.io/content/win10/samples/SPIDisplay.htm.

    Unfortunately you will need to have a datasheet for the device that describes the commands use to initialize it, address a certain location on the screen etc. Many of the datasheets provided with these screens are woefully inadequate.

    The product group are actively investigating alternative mechanisms for these type of displays but they have not yet made a firm decision.

  • there is no driver, but you can write a c# app to draw things on the lcd using gpio.  I've written a basic app that draws pixels and boxes and such but for the spotpear 3.2' lcd (https://github.com/DarrenTweedale/waveshare32bIOT).  You will have to have a look at the reference/datasheet for the exact commands.

    The code is basic.  haven't had time to refine things better/clearer, but will be planning to expand it a bit to make it some sort of slideshow later.
