I powered it from 1st MCLR pin, put 8mhz oscillator with capacitors into 13th and 14th pin, connected led to 19th pin and led is not blinking.
??? MCLR/VPP is not the power pin. Must supply VDD pins 11 and 32. Please show your complete circuit.
To simplify the test setup, you can run the PIC from internal oscillator. One

Recently I bought OLIMEX pic18f4550 (link: ). I am trying to interface it with PICkit by microchip. When I am trying to setup my IPE tu=o just test blinking led code under Tools I cannot find any option to select (Screenshot attached)

Tried so many code but fail to interface....
OR please correct attached file
Your main.c code has nothing there, just a blinking led on while(1) loop.
In addition, there isn't a single evidence of an attempt to interface with this JHD240128.

I actually figured it out while I was typing this. I had the "lo" led wired wrong.
Yes. It could be seen much better with a sketched schematic.
Still, curious why the potentiometer isn't adjusting the speed of the blinking.
Because it's not wired as variable resistor. You have the potentiometer wiper unconnected.

Hi. Cannot 'read between lines'...
The data sheet for IC PCA9901 shows on page one :
"The PCA9901 is a 20 mA current source for a single led that allows stand-alone blinking
of a predefined pattern to off-load the microcontroller and save battery power.
Programming of the device is done through a training sequence: the host controller sends

Try to see whether you can put 2 or 3 led's in series. Each string needs a resistor (several hundred ohms).
Thus if your strings are 2 led's each then you'll need 75 resistors (maybe 400 or 500 or 600 ohms).
If 3 led's each then you'll need 50 resistors (maybe 200 or 300 or 400 ohms).
Brightness depends on how well the mosfet conducts, (...)

From personal experience, I can tell you that if you accidentally use a DC adapter that outputs a higher voltage than is specified, the power led will blink on a Xilinx Spartan development board. In my case, going back to the proper charger stopped the blinking. Unfortunately the overvoltage had damaged something else on the board and it was no l

Did you provide proper heatsink to these leds ? I mean, did you tied them to some bulky metalic plate, or left them hovering as shown in the picture ?

Congratulations on getting the Esaki effect to work. This appears to be one of those unusual circuits, which causes you to have to stick to it until all adjustments are just right.
I would like to make fade in if is possible.
To do this you must change the duty cycle. According to another video, it blinks faster as you increase sup

Why is this? Can some explain me the difference between ISE and Vivado with respect to led blinking program?
Are you using the exactly the same logic blocks to generate the bitstream for Vivado as in ISE?
You mentioned using SDK for Vivado which indicates there is some kind of embedded uP being used, due to which it is necessary to

My arduino Nano is not working. Pin 13 led is blinking with the normal sketch but same program (with other Digital pin) is not giving any results. resistor, led gnd are all in place. This is giving me headaches.

Now, the led can stay still for each word but I would like it to blink and it has to use multiplexer(in 74 series) for blinking.
I have found 74153 use for blinking but I can't connect it to my system on Proteus.
So, if you know how it work Please help
Proteus was included.
and photos represent how it blink but i cannot do.
