> > > @patacongo I was digging into the nxterm code, to see if I could easily use it for testing, but I did not see a way to point it at a keyboard device directly. Is it expected that I create a thread that polls on /dev/kbda and then calls `NXTERMIOC_NXTERM_KBDIN` via `BOARDIOC_NXTERM_IOCTL`? Yes, that is how it currently works. Some of that logic is very old; some aspects of the design might benefit from some re-design. Note that that thread could like in your featherwing driver logic. There is a function in nxterm_driver.c called nxterm_ioctl_tap() that permits the nxterm ioctl commands to be called from within the OS. You might even be able to come up with a solution that does not require a dedicated "listener" thread. Perhaps keyboard input could be handled on the work queue and nxterm_ioctl_tap() could be called directly. This makes sense because the featherwing is really an integrated solution, is it not? There used to be graphics that showed the threading models for NxWM and for Twm4Nx. There is still a link here for NxWM: https://cwiki.apache.org/confluence/display/NUTTX/Graphics, but it is broken. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
