^^^^^^^^^^^^^^^^^^^^

|

||||||
|
This configuration implements a simple touchscreen test at
|
||||||
|
apps/examples/touchscreen. This test will create an empty X11 window
|
||||||
|
and will print the touchscreen output as it is received from the
|
||||||
|
simulated touchscreen driver.
|
||||||
|
|
||||||
|
CONFIG_EXAMPLES_TOUCHSCREEN_BUILTIN - Build the touchscreen test as
|
||||||
|
an NSH built-in function. Default: Built as a standalone problem
|
||||||
|
CONFIG_EXAMPLES_TOUCHSCREEN_MINOR - The minor device number. Minor=N
|
||||||
|
correspnds to touchscreen device /dev/input0. Note this value must
|
||||||
|
with CONFIG_EXAMPLES_TOUCHSCREEN_DEVPATH. Default 0.
|
||||||
|
CONFIG_EXAMPLES_TOUCHSCREEN_DEVPATH - The path to the touchscreen
|
||||||
|
device. This must be consistent with CONFIG_EXAMPLES_TOUCHSCREEN_MINOR.
|
||||||
|
Default: "/dev/input0"
|
||||||
|
|
||||||
|
The following additional configurations must be set in the NuttX
|
||||||
|
configuration file:
|
||||||
|
|
||||||
|
CONFIG_INPUTP=y
|
||||||
|
(Plus any touchscreen-specific settings).
|
||||||
|
|
||||||
|
The following must also be defined in your apps configuration file:
|
||||||
|
|
||||||
|
CONFIGURED_APPS += examples/tiff
|
||||||
|
CONFIGURED_APPS += graphics/tiff
|
||||||
|
|
||||||
|
The board-specific logic must provide the following interfaces that will
|
||||||
|
be called by the example in order to initialize and uninitialize the
|
||||||
|
touchscreen hardware:
|
||||||
|
|
||||||
|
int arch_tcinitialize(int minor);
|
||||||

int arch_tcuninitialize(void);
