I've got questions about HSMC port of Cyclone V GT FPGA Development Board. I need to use that port to SPI communication and I/O. I've read its datasheet and I've notice I can use it like I/O port (?) My questions are: 1.- Can I use HSMC port to SPI communication of 50MHz?? If I can do it, Do I need another board, conector or anything? 2.-I've noticed that HSMC ports has 172 pins (120 are signals), I need to know if I can use that 120 pins like I/O. Can I use it like I/O? If that is true, Do I need another board, conector or anything? I need to used 100 I/O or SPI comunication and I don't know if that port lets me use it like I/O or SPI. I've never used that port, therefore I'm asking here. Thank for reply!!
