void TP_WaitBusy( TPRequestCommandFlag command_flgs );
Waits until processing is finished for touch panel request instructions that have been sent to ARM7
By providing the logical sum of multiple flags in the argument, you can check them simultaneously.
This function uses an interrupt to wait for a completion response from ARM7. If it is called while FIFO receive interrupts from ARM7 are prohibited, it may not be possible to return from wait.
TP_REQUEST_COMMAND_FLAG_SAMPLING |
Requests sampling one time. Send with TP_RequestSampling. |
TP_REQUEST_COMMAND_FLAG_AUTO_ON |
Requests to begin autosampling. Send with TP_RequestAutoSamplingStart. |
TP_REQUEST_COMMAND_FLAG_AUTO_OFF |
Requests to end autosampling. Send with TP_RequestAutoSamplingStop. |
TP_REQUEST_COMMAND_FLAG_SET_STABILITY |
Requests to set chattering provision parameters. Send with TP_RequestSetStability. |
Argument enumerators are described below.
