# TP_RequestRawSampling

## Syntax

  `#include <nitro/spi.h>`

      u32 TP_RequestRawSampling( TPData * result );

## Arguments

result | Pointer to the variable to get touch-panel values.

## Return Values

Returns 0 if the request succeeds; returns non-zero value if it fails.

## Description

This synchronous function requests from the ARM7 processor the current touch-panel values for a single event and waits until those values are acquired. The values (which were already checked for chattering) are acquired as uncalibrated, raw values (x- and y-values take the range of 0 to 4095). This command cannot be used during autosampling.

Note: This function can get touch-panel values even during MIC auto sampling.
However, this function is executed the next time the microphone sampling ends. Therefore, it may take longer than usual for the function to respond.

## Note

This function uses an interrupt to wait for a completion response from ARM7. Notice that if it is called while FIFO receive interrupts from ARM7 are prohibited, it will not be possible to return from wait.
