Function Documentation

tscMeasure()

void tscMeasure	(	u32	command,
		u16 *	buffer,
		u32	count
	)

Read multiple 12-bit measurements from the NDS-mode TSC.

Parameters

command	Measurement command.
buffer	Output buffer.
count	Number of measurements to read.

tscRead()

u16 tscRead

(

u32

command

)

Read a single 12-bit measurement from the NDS-mode TSC.

Parameters

command

Measurement command.

Returns

Measured value, from 0 to 4095.

tscReadTemperature()

s32 tscReadTemperature

(

void

)

Read temperature from the NDS-mode TSC.

Note that it is not very accurate.

Returns

Approximate temperature, in 20.12 fixed point, as Celsius degrees.

tscTouchPenDown()

static bool tscTouchPenDown ( void  )

inlinestatic

Check if the NDS-mode TSC is registering pen input.

Returns

Returns true if the TSC registers that the pen is down.

tscTouchReadData()

bool tscTouchReadData

(

touchRawArray *

data

)

Read raw touch data from the NDS-mode TSC.

Parameters

data	Struct to hold the read data.

Returns

On success, true. On failure, false.
