This application note introduces how to interface AD7276 high speed data converter with Blackfin® processor. It also provides an example code to demonstrate how to program the Blackfin processor's serial ports (SPI and SPORT) to receive data from AD7276 device in both core access and DMA access modes. Power-down mechanism between ADC conversions in DMA mode is also introduced. The entire reference design is implemented on ADSP- BF535 EZ-KIT Lite™ board.
