Hi Florian, Nick,
You both added V4L2 touch pad drivers to the kernel, but I was wondering
about userspace support for such devices. Is there a library somewhere that
can interpret the data?
The only link I found is https://github.com/ndyer/heatmap/commits/heatmap-v4l
but that appears to be mostly a test utility.
Vandana is adding touch device emulation to the vivid driver, so it would be
interesting to see if a library exists for such devices to simplify testing.
Regards,
Hans
