AXInit

Syntax

#include <revolution/ax.h>

void AXInit(void);

Arguments

None.

Return Values

None.

Description

Among other things, the AXInit function initializes the AX library, starts the audio DSP task, and starts AI-DMA.

This function must be called before any other AX functions. The application must ensure that the AI library has been initialized before calling this function.

Also note that AX requires the use of the default stack for AI (in other words, the AIInit function must be called with a NULL argument).

Note: This function calls the AIRegisterDMACallback function internally. Because of this, any AI DMA interrupt callback set using the AIRegisterDMACallback function before this function was called will be overwritten by the AX callback. If you are using an original AI DMA interrupt callback, be sure to set it using AIRegisterDMACallback only after calling this function.
