rs232 uart ip :: user guide

hi,

thanks much for the information Alex,

do i really need a "C' code to send the data to pc, I am taking default "hello world program as my reference". so i am confused , because if i need a C code , then how i will transfer output of verilog code to c code to print it in pc ? i mean how to connect verilog code and c code?

else after generating the qusy system ( nios II + on chip ram + rs 232 uart) , can i connect it directly using verilog & then transfer to putty ?

thanks and regards

update ::::::::::::::::

basically if "" output [7:0] x_out " is my output register how can i access it using c code (if we need c code for this ).

thanks in advance
