Firmware Upgrade
As mentioned before, besides current products with ADAU1701 DSP, we
will develop products with ADAU1452 in future.
WONDOM products with ADAU1701 DSP communicates with SigmaStudio
via I2C, while products with ADAU1452 plans to communicate with
SigmaStudio via SPI. Therefore, we leave the switch for future use with
ADAU1452 products.
Therefore, besides setting SW1 at
① “
USBi
”, we need to set SW4 as well
before programming.
Set SW4 at
② “IIC” when you want to program products integrated with
ADAU1701;
Set SW4 at
① “SPI” when you want to program products integrated with
ADAU1452.
