# TP_RequestSamplingAsync

## Syntax

  `#include <nitro/spi.h>`

      void TP_RequestSamplingAsync( void );

## Arguments

None.

## Return Values

None.

## Description

This asynchronous function requests from the ARM7 processor the one-time touch panel values at that time. After calling this function, you can read touch panel values using the `TP_WaitRawResult` or the `TP_WaitCalibratedResult` function. This command cannot be used during TP autosampling. Even during MIC auto sampling, this function can be used to obtain the touch panel value. (TP auto sampling is not permitted.) However, this function is executed the next time the microphone sampling ends. Therefore, may take longer than usual for the function to respond.
