Command for pcm1738

[sergioby]

Hello everyone.
I'm new to the forum, I have this problem, this BB PCM1738 audio converter requires a command to work, by default it is set to 16bit "FMT 000", I would like to be able to use the other settings too so I thought about using Arduino to send the commands but I didn't I know how to do it.

Anyone have any ideas on this?

I found some info online but programmed in C so I would like to use Arduino nano and create the program.

Need help!! with PCM1738 and uP code

That is the suggestion:

/* defines */

#define F_CPU 1200000 /* for ATtiny13, running at 1.2MHz */

#define DATAPORT PORTB
#define DATAPINS PINB
#define CSPIN 2 /* PB2 (Pin#7) /
#define MCPIN 1 / PB1 (Pin#6) /
#define MDIPIN 0 / PB0 (Pin#5) */

/* macros */

#define CS_low() DATAPORT &= ~_BV(CSPIN)
#define CS_high() DATAPORT |= _BV(CSPIN)
#define MDI_low() DATAPORT &= ~_BV(MDIPIN)
#define MDI_high() DATAPORT |= _BV(MDIPIN)
#define MC_tick() { DATAPORT |= _BV(MCPIN); _delay_us(1); DATAPORT &= ~_BV(MCPIN); }

#include <avr/io.h>
#include <util/delay.h>

void write_register(uint8_t reg, uint8_t value)
{
uint16_t word= (reg << 8) | value;

CS_low();
for (uint8_t i=0; i<16; i++)
{
if (word & 0x80)
MDI_high();
else
MDI_low();
MC_tick();
word <<= 1;
}
CS_high();
}

int main(void)
{
/* hardware init*/
/* all pins input, except CS, MC, MDI /
DATAPINS=(_BV(CSPIN)|_BV(MCPIN)|_BV(MDIPIN));
/ all pins H (pullups enabled), except MC */
DATAPORT=~_BV(MCPIN);

/* write DAC register(s) */
write_register(18, 0x50);

/* endless loop */
while (1) ;
}
