how can i do it in eclipse? this is the project i want to accomplish. i have a 4x3 keypad that will serve as a source for my password that will display in the lcd then when the password is correct the solenoid will open or close but if the password is wrong the buzzer will buzz. the solenoid and buzzer are connected to gpio and the keypad also is connected to gpio. can you give me a pattern or something i can use to finish this project. thank you.

Hi, what did you already made ? I presume you use NIOS II, SOPC or QSYS, an Altera dev board ?

yes i have these so far. //======================================================= // This code is generated by Terasic System Builder //======================================================= module gpio1( //////////// CLOCK ////////// CLOCK_50, CLOCK2_50, CLOCK3_50, //////////// LED ////////// LEDG, LEDR, //////////// KEY ////////// KEY, //////////// LCD ////////// LCD_BLON, LCD_DATA, LCD_EN, LCD_ON, LCD_RS, LCD_RW, //////////// GPIO, GPIO connect to GPIO Default ////////// GPIO ); //======================================================= // PARAMETER declarations //======================================================= //======================================================= // PORT declarations //======================================================= //////////// CLOCK ////////// input CLOCK_50; input CLOCK2_50; input CLOCK3_50; //////////// LED ////////// output [8:0] LEDG; output [17:0] LEDR; //////////// KEY ////////// input [3:0] KEY; //////////// LCD ////////// output LCD_BLON; inout [7:0] LCD_DATA; output LCD_EN; output LCD_ON; output LCD_RS; output LCD_RW; //////////// GPIO, GPIO connect to GPIO Default ////////// inout [35:0] GPIO; //======================================================= // REG/WIRE declarations //======================================================= wire keyboard_val; matrixKeyboard_drive ( .i_clk(CLOCK_50), .i_rst_n(1), .row(GPIO[3:0]), // ???? ? .col(GPIO[7:4]), // ???? ? .keyboard_val(keyboard_val) // ??? ); //======================================================= // Structural coding //======================================================= assign LCD_BLON = 1'b1; assign LCD_ON = 1'b1; gpio ( .pio_led_export(LEDG), // pio_led.export .pio_gpio_solenoid_external_connection_export(GPIO[15:13]), // pio_gpio_solenoid_external_connection.export // pio_in.export .reset_reset_n(1), // reset.reset_n .lcd_data(LCD_DATA), // lcd.data .lcd_E(LCD_EN), // .E .lcd_RS(LCD_RS), // .RS .lcd_RW(LCD_RW), // .RW .clk_clk(CLOCK_50), // clk.clk .pio_key_export(KEY), // pio_key.export // pio_out.export .pio_gpio_buzzer_external_connection_export(GPIO[18:16]) // pio_gpio_buzzer_external_connection.export ); endmodule

and i'm using a de 2 cyclone IV board.

what i did was add a module of a keypad in the quartus II is that right?

Did you use Qsys to integrate the system? Is gpio1 top level module? The code appears hand coded. It can work, but you need to import the gpio1 into Qsys. LCD and PIO can be readily integrated through Qsys. That is also where NIOS II, along with memory for instruction and runtime storage are instantiated. Since all components are available in Qsys, I am not sure why gpio1 has to be coded this way. After getting system constructed in Qsys, Eclipse IDE can be called out to work on software part.

"Hello world" is the simplest example I can think of. If you look at its main(), there is only 1 line of code. You don't even need to understand what it means for the moment.

The idea is to make sure you understand the whole process and verify the correctness of system generated and compiled. I don't see the point with other example if you do not know how to compile and load into NIOS in eclipse. The compilation and loading process are the same. How would other example help?

sir because i'm not that good in programming and the examples hello world doesn't use multiple inputs and outputs

So, did you manage to get hello world compiled and working?
After that, attach what you have modified in the C source code. Does not matter if it does not compile or working. We can work from there.
