Question:
Example code for SPI Dual mode in ADSP-21569 processor
Answer:
The attached example code demonstrates SPI Dual Mode data transfer using DMA mode between two ADSP-21569 Evaluation boards. The code has been tested using CCES3.0.2 with EV-21569-SOM EZKIT and LITE Boards. The following external connection need to be done between both hardware units for testing the application.
Hardware used:
Controller: EV-21569-SOM (REV B) WITH EV-SOMCRR-EZLITE (REV B)
Peripheral: EV-21569-SOM (REV B) WITH EV-SOMCRR-EZKIT (REV A)
SPI0 (TX) - SPI1 (RX)
CLK - CLK
SEL2 - SS
MOSI - MOSI
MISO - MISO
