12 years ago --- Quote Start --- can you connect the oscilloscope to which ever is the TX pin of your DE1 ? If you send a single character you should be able to capture it on the scope and verify that your verilog/firmware code is working and not your terminal application or chip. --- Quote End --- I transmit character U (85 = 01010101) in cycle with using Terminal v1.9b, and i tested TxD pin on FTDI UM232R module with oscilloscope. It's work !!! Screenshot in attachments - ss1.jpg And i connect TxD pin to RxD pin on FTDI UM232R module and i saw "echo" on Terminal v1.9b. UM232R is work !!! Screenshot in attachments - ss2.jpg And now i think, that problems has Verilog modules with transmitter/receiver. From site http://www.fpga4fun.com/serialinterface.html. I only changet default clock 50 MHZ to 24 MHZ. Why it not work ??? --- Quote Start --- Altera also has their own UART module which you add in Qsys/SOPC builder, this provides a GUI interface that you can use to just select the baud rate that you want. --- Quote End --- I have free quartus 13.0 web, and megacores functions set is not included to this free edition. I have question - For use this "their own UART module" i must buy all quartus 13.0 subscription edition or i can buy only this single megacores function (or set of all this functions).
