I'm using Ken Chapman's uart_tx in a Spartan3A design.
The HDL compler can't find the module/primitive, so I wonder if I did everything right here.
What I did was the following:
- Download and unpack xapp223.zip from Xilinx
- Include uart_tx.EDN in my design, no problem
- Instantiate it in my code, copy/paste from Spartan3A demo source "terminal.v"
- Compile, got error
I know the uart documentation says it's fit for any Virtex or Spartan- II, but seeing that it works in the Spartan3A demo I should be able to use it in my code on the same board.
Can you explain what went wrong here?
Thanks, B=F8rge
Here's my instantiation: uart_tx uart_transmitter ( .data_in(outdata_uart), .write_buffer(write_to_uart), .reset_buffer(reset_local), .en_16_x_baud(en_16_x_baud), .serial_out(RS232_DCE_TXD), .buffer_full(uart_buffer_full), .buffer_half_full(), .clk(clk_100) );
