UART

[LEDN]

HELLO

How can i assign in "Pin Planner" the pins GPIO[0] = Tx, GPIO[1]= Rx , and GND on DE10-LITE

I wan to send data over UART.

 my code similar like this

module UART_RX
#(parameter CLKS_PER_BIT = 217)
(
input CLOCK_50,
input i_RX_Serial,
output o_RX_DV,
output [7:0] o_RX_Byte
);

module UART_TX
#(parameter CLKS_PER_BIT = 217)
(
input [1:0] KEY,
input CLOCK_50,
input i_TX_DV,
input [7:0] i_TX_Byte,
output reg o_TX_Active,
output reg o_TX_Serial,
output reg o_TX_Done
);

where can i change Pin Planner in my software? ( GPIO[0] where can i set in UART_TX?, is it input or output? Same as RX. ). Im a new uart i try to understand uart.


Thanks.

Have you downloaded the manuals, tools, and examples CD from TerAsic?

Ref: https://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&CategoryNo=234&No=1021#contents

Look under Resources.

The SystemBuilder application can generate a .qsf file definition to include with Quartus that defines all the chip I/O assignments.

On the CD image, under Demonstrations, you might want to look at the Golden_Top example files to get you started.

you mean set the wire to the board. i already know that. my question is on the software Quartus not on the board. i want to know how you write code to connect board to Putty by using my function as above by connect  the pins GPIO[0] = Tx, GPIO[1]= Rx.

Well, I don't  understand what your question is then.

In your original post above, you asked about assigning pins in Quartus using the Pin Planner. I responded to that. TerASIC has a tool (the SystemBuilder) to facilitate defining the device pins to Quartus.

In your followup I am not sure what you are asking. You say your question "is on the software Quartus not on the board". That is what I answered.

Physically, the DE10-Lite has no RS232 serial connector nor does it have any embedded 3.3V-LVTTL-to-RS232 converter device.
So you will need to attach a physical LVTTL-to-RS232 or LVTTL-to-USB-serial converter board/cable to communicate to a PC via serial.

Good luck. I am done here.

Hi,

Based on this DE10-Lite User Manual (page 30), 

GPIO_[0] is at PIN_V10

GPIO_[1] is at PIN_W10

If you want to set GPIO[0] = Tx, then signal o_TX_Serial has to be assigned to PIN_V10 and Tx will be output.

If you want to set GPIO[1] = Rx, then signal i_RX_Serial has to be assigned to PIN_W10 and Rx will be input.

Best regards,
Sheng
