Honored ContributorHi,
In my project am using 4 FPGAs 1) First FPGA am using Nios II 2) I want to access/ Control Other FPGA registers so i have created a custom protocol in slave and master side ir Nios side am planing to do it in C code? can u tell some ideas of c application how we can start???
Honored ContributorWhy do you want to use a custom protocol. Why dont you model the interface as MASTER - SLAVE SPI interface and do a write cycle with address of register and read cycle with teh value of the register.
Honored ContributorUser want to access via UART and access all other FPGAs thats why SPI is not using
