Hello,
Yet another request for recommendation of an embedded linux board/module I'm afraid. The requirements are pretty specific, I haven't seen anything in my searches with the entire feature set I need, but the expected quantity (~30) is unlikely to justify a custom build.
Core platform:
- >= 200MHz system clock * >= 32MB DRAM * >= 16MB Flash * CompactFlash / SD card slot * 3x SPI interface (ideally multiple independent channels, but multiple chip selects OK) * USB host controller * VGA
- Linux 2.6.recent support for all of the above (esp. drivers)
The USB + VGA is for touchscreen module interfacing, so a unit with builtin or optional touchscreen module is also suitable (8/16 bit colour, 7-8" diagonal)
It's the SPI headers and VGA/TS that seem to be the showstopper.
Looking at Gumstix.com/org, there is a bit of info on connecting LCD modules to Gumstix but it looks pretty hacky. And no info re: touchscreen support. SPI also draws a blank.
Any suggestions and recommendations greatly appreciated.
Thanks,
John
