Our implementation uses a PC running the NOS C code in Visual C# to send SPI commands through a FPGA to the AD9361. The chip is functional (change RX LO, RX Bandwidth, read RSSI, etc), but I was not sure the purpose or how to implement the AXIADC_INIT, AXIADC_READ or AXIADC_WRITE functions in platform.c. I did not see anywhere in the documentation the purpose or use of these functions. The sections of code that call the AXIADC functions are also not commented to describe their purpose.
Please help me understand what these reads and writes are doing? I do not even know what address space that they are attempting to access.
