Hey everyone,
I'm working on this project that I want to control using a touch screen GUI. But I could really use some help.
I've been searching and reading datasheets/specs for ages now, looking at single board computers, microprocessor boards, smart displays, embedded GUI solutions,.. etc. But nothing I've found so far seems to do what I need. So therefore I want to appeal to the expertise of the users on this forum.
The device I want to control has just one way of communicating; SPI (as the master).
And I'm looking for a touch screen solution that has its own LCD controller, MCU/Soc, (flash) memory etc .. because no video information is to be sent thru the SPI bus, really only some control information. So the essential properties I'm looking for are the following:
- GUI device has to be in SPI slave mode.
Directly supported both in hardware and in software.(because I found some solutions, like an oLinuXino which seemed ideal, until I found it's Linux OS, doesn't support SPI directly, and only half duplex. And I need to compile my own custom kernel, which is beyond my skills)
- being able to connect a 7" touch screen
- preferably a single board computer or microcontroller board.
Because of the many expansion possibilities. Down the line I need to connect some analog inputs. Either directly or thru an analog input board.
- fast booting OS
if the OS is Linux, Android, etc ... or based on.
It would be great if someone could recommend me a good board. Or point me in the right direction because I'm stuck at the moment and I'm so excited to continue my little project that has got me back into electronics since years.
thank you, any help will be much appreciated !
