CONFIG_SIM_TOUCHSCREEN=y CONFIG_SIM_TOUCHSCREEN=y
Then you must also have some application logic that will call Then you must also have some application logic that will call
up_simtouchscreen(0) to register the touchscreen driver. sim_tcinitializ(0) to register the touchscreen driver.
NOTES: NOTES:
1. If you do not have this call, the build will mysteriously
fail claiming that is can't find up_tcenter(0 and up_tcleave().
That is a consequence of the crazy way that the simulation is
built and can only be eliminated by call up_simtouchscreen(0)
from your application.
2. You must first call 1. If you do not have the call to sim_tcinitializE(0), the build
will mysteriously fail claiming that is can't find up_tcenter()
and up_tcleave(). That is a consequence of the crazy way that
the simulation is built and can only be eliminated by calling
up_simtouchscreen(0) from your application.
2. You must first up_fbinitialize() before calling up_simtouchscreen()
or you will get a crash.
3. Call sim_tcuninintialize() when you are finished with the
simulated touchscreen.
4. Enable CONFIG_DEBUG_INPUT=y for touchscreen debug output.
