[@LucasFerreira-tu4to]

Thank you for the video professor! Took me a while to debug my code, but I finally got it running (I'm using a board with a Cyclone IV and Quartus Prime Lite). Looking forward to the next videos!

[@ElectronicswithProfMughal]

Glad Lucas that you enjoyed :)

[@ElectroWolf_Arts]

i build it with logic gates , transfer it into a VHDL code by Multisim software and thn uploaded that code on the fpga board ..... it was simple , i also made a 4 digits locking system and a simple automation segment , they all was simple.......thats the problem , i will face future problems due to my ignorance of programming , projects like "vga display" or "CNC machine"

[@ElectronicswithProfMughal]

Doing it that way, I call it cheating 😛 But great job (y)

[@ElectroWolf_Arts]

@@ElectronicswithProfMughal yeah you can say that , that clock tooks me around 350 logic gates including flipflops and counters and debouncers ... , but this methode is so limited

[@giovannibetances5023]

the push buttions are not working for me plz help

[@drbalontotis2474]

So thanks man

[@vishnusuggula9036]

I think push buttons won't work with this code as expected because when you press the button we will at least press it for few milliseconds lets take a best case that you will press for 1ms (actual value will be higher than 1ms) then in this code in always @(posedge clk) number of "posedge clk 's" will be 10^5 so the button will be high 10^5 always cycles so if you press minup - button even if it is for 1ms , min

Hi sir do you know how to solve this problem?

Thank you :)

[@st_lim_st1154]

Hi prof, if im using spartan 3e with 50Mhz oscillator clock, do i need to slow the clock down to 1 hz beforehand? and what actually is the function of declaring a localparam?

[@ElectronicswithProfMughal]

Yes, you'll still need to slow down the clock, and because the board clock is 50 MHz, which means the count value will be different from what is shown in the video because Basys 3 board has a frequency of 100 Hz. Declaring localparam is helpful so you can use assigned variables that carry some pre-stored values. If your machine has any states, it is helpful to use localparam command.
On how to slow down the clock, please watch this video - ua-cam.com/video/pFHKVLrjOSk/v-deo.html

thank you so much for the video

Glad you like it :) thanks for watching.

[@angeldavidsotoosornio8926]

question, is it possible to turn on the two leds in the middle of the display ?... (" : ")

[@ElectronicswithProfMughal]

Yes, it is. You should use a constraint file that has those ports and their addresses.

thanks for the video. really helpful

How much price will fpga board cost

[@ato-qt4rx]

do you have basys3 fpga code for buttons

[@ElectronicswithProfMughal]

see the link for it in the description.

[@Hersparklinggqalb]

Hi sir can i do this without the hardware kit to see the output by simulating this instantiated codes?

[@ElectronicswithProfMughal]

Smile yes, you can do that without the board itself. Good luck :) just create a testbench file and simulate it.

[@doo.dlebyk]

well explained sir thank you!!

[@ElectronicswithProfMughal]

Thank you Keerthi. Glad you liked it.

[@ankamanirudh8837]

Sir I have one doubt
I am confused to choose clock frequency
My sir said to operate clock at 1hz so what changes should I do?
Simply I just need to kept
always #1 clk= ~clk; that's it?

[@ElectronicswithProfMughal]

Ankam, we've chosen 1 Hz clock in this project. You can also watch this tutorial on how to set a slow clock - studio.ua-cam.com/users/videopFHKVLrjOSk/edit

Is system verilog also required or simply verilog is enough?

[@ElectronicswithProfMughal]

Dear Manish, depends upon what your end goal is. You can do both.

@@ElectronicswithProfMughal fpga projects u teached are based on only verilog or system verilog?

[@ElectronicswithProfMughal]

Dear Manish, like I told you previously, it is upon your discretion and the simulation platform you’re using. I am using system verilog using Vivado.
