There's touch panel support in eCos for the Cirrus Logic EDB7xxx boards - see hal/arm/edb7xxx/current/misc/lcd_panel_support.c but it was done somewhat ad hoc I believe - it wasn't formalized into a proper interface. This may be because it's too simple to bother formalizing, I don't know. Gary, this is your baby - any opinions? Jifl -- Red Hat, 35 Cambridge Place, Cambridge, UK.

The basic idea is that the touch screen handler creates small events which are placed in a kernel message buffer which users can read. The EDB7xxx touch driver is the only one we've played with so far. We'd certainly appreciate more contributions in this area. ^ permalink raw reply [flat|nested] 5+ messages in thread

It was a glitch in the process that generates the tree. I actually spotted it before the commit on Friday, but by then we had introduced some rather nasty incomplete changes to the internal tree that would have broken more targets than that. I was hoping no-one would notice until today when I could fix it :-). If you can do without the flash package, just comment out the entry in ecos.db for now. I'll be redoing the update later this afternoon. Jifl P.S. Say hi to Stef and tell him I want my video back ;) -- Red Hat, 35 Cambridge Place, Cambridge, UK.
