using UART to communicate between fpga and pc

Hi i am using Altera Stratix® V GX FPGA (5SGXEA7N2F45C2) and i have designed the UART program to communicate between the fpga and my pc. and the compilation was a success,...

Hi ak6dn,

Thank you for you are reply. My bored is not my own custom made it was manufactured by TERASIC company. i have one more board that is ARRIA V V GX 5AGXFB3H4F35C4N, which was released by Intel i self.

i went through both the data sheets but i cannot find the UART RX and TX to external RS232 transceivers (or LVTTL).

Well, looks like your are out of luck for RS232.

It appears you have the DE5-NET TerASIC board (the only one TerASIC has that uses the StratixV part you refer to) and that board is basically a PCIE add-in board with SFP+ module support for networking.

There is no RS232 support on board. There is no generic I/O pin availability via a header.

There is only an RJ45 connector present that has an RS422 transceiver. Using that is your only option.

That board is basically designed to act as an add-in accelerator to a computer via the PCIE bus with high speed network support via SFP+ module connectors. Not a good choice for a generic development board.

So you need to either rewrite your code to use RS422 instead of RS232, or else find another board.
