Data Structure Documentation

SceTouchDeviceInfo

struct SceTouchDeviceInfo

Cached touch-panel identity and firmware information.

On FW 3.60, the extended Syscon record supplies the first eight bytes. The legacy path supplies the vendor and firmware revisions, obtains the configuration revision separately when supported, and leaves the hardware version and vendor information at zero. The public and kernel getters always set SceTouchDeviceInfo::reserved to zero.

Data Fields
SceUInt16	vendor_id	Touch-controller vendor ID.
SceUInt16	firmware_rev	Controller firmware revision.
SceUInt16	config_rev	Controller configuration revision.
SceUInt8	hw_version	Hardware version used for firmware compatibility.
SceUInt8	vendor_info	Vendor-specific value used for firmware compatibility.
SceUInt8	reserved[4]	Set to zero on FW 3.60.

Function Documentation

VITASDK_BUILD_ASSERT_EQ()

VITASDK_BUILD_ASSERT_EQ	(	0xC	,
		SceTouchDeviceInfo
	)

ksceTouchSetEnableFlag()

int ksceTouchSetEnableFlag	(	SceUInt32	port,
		SceBool	enable
	)

Set touch enable flag.

Parameters

[in]	port	- The port number.
[in]	enable	- The enable flag.

Returns

0 on success. < 0 on error.

ksceTouchGetDeviceInfo()

int ksceTouchGetDeviceInfo	(	SceUInt32	panel,
		SceTouchDeviceInfo *	info
	)

Get touch-panel device information.

The complete output is cleared to zero, then filled from the selected panel's cached information while CPU interrupts are suspended and the Touch state spinlock is held. The panel does not need to be actively sampling.

Parameters

[in]	panel	- One of SceTouchPortType.
[out]	info	- Receives the complete 0xC-byte device-information record.

Returns

0 on success, or SCE_TOUCH_ERROR_INVALID_ARG if panel is not SCE_TOUCH_PORT_FRONT or SCE_TOUCH_PORT_BACK, or if info is NULL.

ksceTouchSetTouchEmulationData()

int ksceTouchSetTouchEmulationData	(	const void *	front_data,
		const void *	back_data
	)

Set front and back touch-emulation data.

Each argument may be NULL. A non-NULL argument points to one 0x90-byte SceTouchData structure for the corresponding panel. On FW 3.60, this function ignores both arguments: it does not read, retain, or modify either structure.

Parameters

[in]	front_data	- Optional pointer to a front-panel SceTouchData.
[in]	back_data	- Optional pointer to a back-panel SceTouchData.

Returns

Always 0 on FW 3.60, including when both pointers are NULL.
