@tangnatalaga wow, i'd actually really appreciate that. I'd design something for you...but something tells me you already know how to do all the simple crap that I know haha. -Joe
-
I can design it for you and send an schematic if you want.
-
you may need some flipflop along with it tho. the 555 timer will set the clock, Its not really that hard. Cuz a chaser is almost a counter except you dont have 7 segment decoder.
-
@tangnatalaga you could obtain the "chaser" effect with a 555 timer?? how? thanks. -Joe
-
Awesome!! i would buy....
-
In fact, I have done it using a PIC chip including setting up the interrupt on B0 to switch between speeds across 3 ports.
-
You can use the classic 555 timer, which is a versatile chip, and fool around with different value caps, and some resistor.
-
It can be done in software, via Pic Chip.

haha wombatppc you chutamarang noob, thought you where one of the special ones, thought you knew what most wouldn't!!! MUUU HA HA HAHA HA YOU KNOW NOTHING!!!! MUU HA HA HA HA

Hi Bill. How did you get the LEDs to stay lit.? make the correct type of dragging effect for the light. any chance of seing a diagram for it.?
wombatppc 5 years ago
The LEDs are each individually dimmable. I do this with what is essentially pulse width modulation. Its all done in a Xilinx CoolRunnerII FPGA, so its all gate logic. Each LED has a counter (0-255) that is compared with a global counter (0-255 running at 1.8Mhz), if the LED has a higher number than the global counter the LED goes on, and if not, it goes off.

So is that through software via a PIC chip.?
I understand what your talking about. !!
Most wouldnt.

Field Programable Gate Arrays (FPGAs) contain no actual programs or software. Its just a combination of and/or/xor/etc logic gates.
