Hello.
i my application i need different selectable mclks 22, 24,45,49 MHz.
I need the 45, 49Mhz set only to support 356kHz and above. XU208 TQ64
Problems is that the xmos audio software costumdefines.h have defines for
only two mclks tasks.
EG 45,49 MHZ
/* Master clock defines (in Hz) */
#define MCLK_441 (1024*44100) /* 44.1, 88.2 etc */
#define MCLK_48 (1024*48000) /* 48, 96 etc */
EG 22,24 MHZ
/* Master clock defines (in Hz) */
#define MCLK_441 (512*44100) /* 44.1, 88.2 etc */
#define MCLK_48 (512*48000) /* 48, 96 etc */
Normally i do the oscillator selection in the audiohw.xc
If(samplerate % 22050 ) = 0 -> Switch on via GPIO
How can i switch between eg 22 and 45 Mhz ? if i use one set of defines the clock calculation went wrong.
Best regards
Andreas
I need to switch four mclk oscillators.
Locate define using and replace with variable code...
Good idea. Thanks. I will have a look next week.
