Hi, I have little display attached to my raspberry, description found at https://learn.adafruit.com/adafruit-pitft-28-inch-resistive-touchscreen-display-raspberry-pi It uses SPI interface for bouth display module and touch panel overlay, so my question is - do we have any example how a SPI connected device could be used? This module uses ILI9341 as TFT driver/controller and STMPE610 for touch screen interface, both in SPI mode. As datasheets are available on internet, it should not be too hard to write a driver, but first some example would be great... Do we have anything like this? I could try to look how it is done on raspbian linux, but as internally this is totally different, I would like to avoid this, not to mention I have a hard time understand linux kernel sources... Regards, Milan
