The commands are of necessity 16-bits. Using 16-bit words means this driver won't run on as many systems; folk will still need to use the ads7846 driver with tsc2046 chips.. and does not include > temerature > >> or voltage sensing capabilities.

Something the ads7846 driver could benefit from too ... again, two drivers is counterproductive. - Dave ------------------------------------------------------------------------------ _______________________________________________ spi-devel-general mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/spi-devel-general
