HiI am using 3 wire SPI IP from the prime Software. I didn't found any document which says how to pass the data or how to use this IP. In this IP, Input side 3 wire SPI IP, which is Avalon memory mapped interface, consisting of data lines, clock, write, read, chipselect signals. Output side 3 wire SPI IP, having SPI interface, consisting of MISO, MOSI, SS_N, SCLK. I am using 5 slave to connect and communicate with 3 WIRE SPI. CAN ANYONE HERE PLEASE TELL ME HOW TO PASS THE DATA OVER 3 WIRE SPI????
Chapter 5 of the "embedded peripherals ip user guide (https://www.altera.com/en_us/pdfs/literature/ug/ug_embedded_ip.pdf)" covers Altera's SPI IP core. See table 21 for the register map which you access via the Avalon MM interface.Cheers, Alex
