HDD POV Clock By FPGA ... Project

[addyyyyy]

Did anyone try to make propeller clock by using FPGA .I alway see most of POV using pic or arduino .

Thank so much for answer.

Ok that´s nice, but you could say a bit more about you and your resources.

Are you fluent in VHDL, or will you be drawing schematics?
Do you have a specific chip or family in mind?
Do you have access to some evaluation board or do you plan to make your own?
How much time AND money are you willing to spend on this project?

 

[addyyyyy]

I have basic knowledge of VHDL and I have several boards of FPGA board . I have 3 months for this project.

What boads and with what chip do you have available?
Did you search how do propeller clocks work? Is this some school project?

yes ,I already search and yes this is project for school

So what do you need help with? Do you have some schematic already?

I have this schematic but i want to change PIC18F252 to use FPGA.

That seems doable, but I suggest you build the hardware first, figure out how you will drive the spindle motor, leds, set up the sensor, etc. and then start playing with the code. Since this clock can only display radial lines, the vhdl code can be pretty simple.

thank for your suggest.

Oh,one question did you used to use LED strip that can command them to shine in different color. If you know please teach me how. Thank

I am not sure what you mean, can you post some link to that led strip? Or you mean multicolour leds?

its just a strip with 3-4 leds in series with a resistor, and this is paralleld across the strip. I think there should exist even RGB ones, which are about the same but have 4 wires running along instead of 2.
