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 (...)
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: (...)
h tried to compile a simple project using eclipse and I have this error: Description Resource Path Location Type make: *** Error 1 led blinking C/C++ Problem how can i solve it??
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 (...)
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 ?
hello everyone..i have a problem on my project..with pic16f877 microcontroller. My project is a 2 button mode led blinking ..Hope someone could help me..the problem is when I press the 1st button it working such code. but when I press the 2nd button it's not working such the code. which I programming in 2nd condition....
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 (...)
I have to make a very simple program for led blinking . Using buttons 1 and 6 lead me.When the button is pressed for a small time , then led 1 should be blinking. This code is part 2 of the led blink. part 1- Lead 5 & 6 part 2- led 1,2,3 & 4 blinking with (...)
Hi, I am testing a simple program of blinking two leds with 8051 uC, one led will blink all the time and another will toggle during an interrupt. I am using proteus simulator and keil v5. Debugging step by step of the code in keil shows it ok while running the code is not giving satisfactory output with (...)
Hi, I am learning RTOS by myself taking ucos-ii and MSP432 evaluation board as a reference. In the reference code, which I download from its website, I find difficulty in creating two tasks(led blinking) that have different priorities. In reference code, BSP_Tick_Init() function called in the call back function so after (...)
Hi. I found at my workplace an evaluation board based on GSM module SIM508 EVB V1.01, manufactured by SimCom What seems to be the problem: I have inserted a valid SIM card; soon after I activate GSM (by pressing Z1 button ) the GSM_NET led start blinking and then stops after 10-15 seconds. During this seconds ,I receive string (...)
Hi, I am making use of the MODEL FS CT6B tansmitter and receiver, which is used to transmit the data wirelessly. First of all I want to test that one For that purpose I am making use of servo motor to switch between the channels First of all I want to test by blinking led by switching between the channels using arduino software . (...)
my Samsung 32 inch 3D smart TV suddenly not starting up.The screen lights up fully with smart TV logo and goes off in half second. Again full same picture and in half second the picture goes off. the leds alternatively light on and go off.I thought the problem was with mother board . any one help with schematic of this (...)
Hey I compiled simple BLINK led by USB example. The example works well on my every day workstation PC. But when I plug it to the laptop, it says "unknown device" (error code 43). What's wrong, am I forgetting some kind of drivers? I am using example HID Read Write Interrupt (EasyPIC v7 for PIC18F4550). The board c
Were you ESD safe? Why are leds shown backwards? Each output is 25 Ohm nominal ESR so if shorted to gnd or supply and active in opposite state , current limit from 3V is 120 mA !! I calculate ESR as follows. ( actually internal RdsOn) ESR = Vol/Iol and (Vcc-Voh)/Ioh - - - Updated - - - Many kits run fr
Reviewing the original question, I'm guessing that he wants just to draw the circuit and layout of a flash-led, being the Pentium4 the PC platform where will run a CAD tool. Seriously speaking, he needs to elaborate more the need. I have an Intel Pentium 4 and i want to design minimum circuit that is require for r
The blinking led fault code is your clue, most likely one of the SMPS. IF it detects over-current in the CCFL backlights, then the SMPS for those may be one possibility. Does the display color look off-white in the corners? If this all points towards expired CCFL tubes, I know TV parts stores and also DigiKey stock a wide range.
