Advanced ADAU1452 DSP Development Board — Electronic Frequency Division

Built for ADAU1452-series applications, this development board lets you select the communication interface (SPI or I2C) from the SIGMASTUDIO configuration page. Addressing details are fixed: SPI 0x1 ADR0 and I2C 0x16 (118). The onboard E2Prom uses SPI 0x1 ADR0 and does not need to be changed. Pin mapping between the USBi emulator and the ADAU1452dsp target board (CN2) differs by mode: - SPI mode: USBi pins 1/3/5/7/9 (CLK/CS/MISO/MOSI/GND) map respectively to CN2 pins 5/4/3/2/1 on the ADAU1452dsp board. - I2C mode: USBi pins 2/4/6 (GND/SCL/SDA) map respectively to CN2 pins 1/5/3 on the ADAU1452dsp board.
