Preface

The LED was tested before, and this article continues to conduct interactive tests in conjunction with the KEY.

New Construction

New project key

Create source file key. Add to project

Enter the following

module key_led(
input sys_clk ,
input sys_rst_n,
input [1:0] key,
output reg [2:0] led
);

//reg define
reg [23:0] cnt;
reg [1:0] led_control;

always @ (posedge sys_clk or negedge sys_rst_n) begin
if(!sys_rst_n)
cnt<=24'd9_999_999;
else if(cnt<24'd9_999_999)
cnt<=cnt+1;
else
cnt<=0;
end

always @(posedge sys_clk or negedge sys_rst_n) begin
if (!sys_rst_n)
led_control <= 2'b00;
else if(cnt == 24'd9_999_999)
led_control <= led_control + 1'b1;
else
led_control <= led_control;
end

always @(posedge sys_clk or negedge sys_rst_n) begin
if(!sys_rst_n) begin
led<=4'b 0000;
end
else if(key[0]== 0)
case (led_control)
2'b00 : led<=4'b100;
2'b01 : led<=4'b010;
2'b10 : led<=4'b001;
default : led<=4'b000;
endcase
else if(key[1]== 0)
case (led_control)
2'b00 : led<=4'b001;
2'b01 : led<=4'b010;
2'b10 : led<=4'b100;
default : led<=4'b000;
endcase
else
led<=4'b000;
end

endmodule

constraint

From the schematic diagram, we can see that LED_R, LED_G, LED_B correspond to J4 H5 J5 respectively

25M clock input corresponds to D7

If there is no dedicated reset button, use KEY0 H3

KEY1 and KEY2 in the schematic diagram correspond to H2 G3 corresponding to KEY0 and KEY1 in the code

The constraints are as follows

Running Tests

Key 0 reset

Press KEY1 and hold it, the running light will light up

Press KEY2 and hold it, the water light will change direction

Summarize

The TD software development process is the same as other platforms, creating a project, adding source code, constraints, compiling and downloading. The overall development experience is not much different, but the GUI interface can still be optimized, and the download is relatively simple. This experience is still good.

This article tests basic IO operations by combining buttons and LED interactions.

Jacktang

The interactive test of buttons and LEDs shows that the code is not much and the effect is very good.
