Hi everyone,
Can someone share the register configuration of triangle wave output for AD9102 with me?
I used the same sequence which is written in AD9102 EVB software(Example 4) however I can not get the output. But I can get sinusoidal output by using the sequence which is given in Example 6.
Best Regards,
Dogukan.
Thanks mcee,
Here is my last register configuration :
//WAV_CONFIG
spi_temp[0]=0x00; spi_temp[1]=0x27; spi_temp[2]=0x32; spi_temp[3]=0x12;
spi_write_DAC();
//PAT_TIMEBASE
spi_temp[0]=0x00; spi_temp[1]=0x28; spi_temp[2]=0x01; spi_temp[3]=0x21;
spi_write_DAC();
//PAT_PERIOD
spi_temp[0]=0x00; spi_temp[1]=0x29; spi_temp[2]=0xFF; spi_temp[3]=0xFF;
spi_write_DAC();
//DAC_DGAIN
spi_temp[0]=0x00; spi_temp[1]=0x35; spi_temp[2]=0x40; spi_temp[3]=0x00;
spi_write_DAC();
//SAW_CONFIG
spi_temp[0]=0x00; spi_temp[1]=0x37; spi_temp[2]=0x08; spi_temp[3]=0x06;
spi_write_DAC();
//START_DLY-Nothing changes actually.
spi_temp[0]=0x00; spi_temp[1]=0x5C; spi_temp[2]=0x0F; spi_temp[3]=0xA0;
spi_write_DAC();
As I get sinusoidal output from the module, my hardware connection is correct. I guess the problem is in the SPI information that I want to send or I miss to use some registers to get triangular output.
But I can't get any triangular output. Can someone advise me something ? (such as, changing the register value or using different registers..)
Best Regards,
