Momentary button to turn on/off LED - LabVIEW FPGA

I started to learn something with the hardware (cRio-starter kit).  I want to implement what is called 'memory' in the engine control is when I press a button (PS1), the LED (LED 1) will change its State and stay until you press PB1.  I tried to apply it, but failed completely.  It must be done with a registry but I just couldn't keep it from Flash.

Hi muahang,

use a shift register to maintain the previous state of the button. Compare the current state of the button with his previous. When you detect a rising edge reverse you the Boolean value of a second register shift. Write the Boolean value of the second register to offset your led...

Key words: boolean, from edge detection, register shift

  • Satellite 1005: Push the power button, will turn off the AC power.

    Laptop: Toshiba Satellite 1005

    Problem: When I press the power button and let go, the laptop immediately loses all power.

    I use the power cord plugged into the laptop, the power supply light is green, but when I press the power button and let go, as soon as the power light goes black(turns off), nothing happens.

    Howerver, if I PRESS the power button without letting go, power LED lights, but the laptop won't boot at all, no Startup logo, no sound no matter what.

    It's the second time this has happened, the first time, I let stand overnight and the next day she booted up fine.

    Currently, the laptop is cold, it did not work, but always the same thing as described above.

    There are no changes made to the laptop.

    Any ideas?

    It seems that the contact, the power button is faulty. Better to elevate the laptop to a Toshiba service station for a check.

    I n ' t´t think that it is a software failure.

    Good bye

  • How can I turn on/off the blue LEDs on the Satellite A100?

    Hello

    Does anyone know how to turn the blue LEDs under the touchpad? They are very nice, but when I go to sleep they light a lot and it is a small problem. Maybe someone can help me or suggest something else.
    Thanks for any answers

    Emil

    Hey Buddy,

    You can't turn them off. If you really want that you would have to reprogram the BIOS. And to do this, you must be a Toshiba engineer and a lot of experience with the low level hardware programming.

    You can also stick the tape on the lights. :)

    That is my suggestion.

  • Pavilion G6 2338sl: hardware button to turn off the touchpad does not work on Windows 10

    Hello

    I have a Pavilion G6 mobile 2338sl. When I was on Windows 8.1 the touchpad worked a lot, so I've updated for Windows 10. Windows updated my drivrs to last, provided also by Synaptics (19.0.19.1). HP says the moment is upgrade from Windows to provide the driver for this laptop, as you can see on the driver support page. The touchpad works, the parameters can be set (gestures etc.), the touchpad turns off when another mouse is connected (it's ok).

    The problem is that if I use the touchpad and I want to turn off the button, it does not work and the computer reacts like a click. So I returned to the old driver and button works. But Windows Update continusly updated the driver (I disabled the option in the advanced settings, but it still update) and I come to every time.

    So I tried to reinstall Wndows freshly (not update Windows 8.1) and with the old driver works, but when she updates to 19.0.19.1, the button to turn off the work stoppage.

    I looked on the interent and someone tips to set minimum detection of palm. I tried but it still not working.

    I hope someone can help me

  • Why doesn't my button to turn off the legend and?

    I have a button that is turns on and turns off a legend in DPS. I saw him in other magazines DPS. I did my research and saw this question asked before, but the response has been of a hotspot button in the legend to turn it off. I would like the button to do both, to turn on or turn off the legend.

    I have attached a jpg of my object state in a screenshot, I made my legend a State and an invisable box state. Then you can see a screenshot of my button build. I'm sure I have my built wrong button.

    Could someone help me please? I do not have anyone to turn to work, it's all here.

    Thank you.

  • Menu button to turn off the audio

    In my current DVD, I have a nice audio background playing until the user clicks on a video button.  However, some people like audio and want to turn it off.  I looked but could not find anything that would allow users to turn off the background music.  Then...  How can I add a button "Disable background music" to my main menu?

    Thank you

    Dan.

    Dan,

    Do not speak on behalf of Stanley, but I think so. It caters the Menu to control things, and I was talking about how to manage the timeline.

    I use several Audio streams often, but more often with the SS of DD 5.1 and DTS. In my case, DTS is not a stream of Audio authorized primary, so he goes to 2 Audio tracks, and my DD 5.1 SS AC3 goes on 1 Audio track, where he would reside, if there was no Audio 2 track. In your case, instead of DTS, you'd have the track "silent."

    These buttons link to the timeline, one directly to the Audio 1 track and the other to 2 Audio tracks. Note: This is done by specifying the link and make the choice on the menu drop down.

    The user can use this Menu to choose, or the Audio button on the remote control.

    Stanley memory is better than mine, as I couldn't remember a version of 'silent '. Now, I field questions about additional Audio tracks with the frequency.

    Good luck

  • T-450 does not turn on/off; flashing lights

    My laptop began to have difficulties to connect. He would often take really long and sometimes it doesn't connect at all. After my last connection, I put my laptop in mode 'sleep', like I always do. I went to use my laptop a few hours later and it would not turn. Before saying that my battery is dead, I know that my battery is not dead, it just the charger. When I try to turn it on, the power button flashes, a second to one second in stop and so do the lights on the keyboard, the backlight of the screen and even the powers of fan on in this interval. At the beginning I could not he same power all long until I found some odd forum on some weird 'code' with the power button, but when I turn it on it comes t - he once again. I also tried to remove the battery among other things. Anyone know what is the problem and how to fix it? Thank you.

  • My 5s iPhone keeps turning it off yourself.

    IiPhone keeps turning it off yourself. Even when battery is fully charged. I do a reset to turn it back on. Seems to be more one morning when it arrives

    Try resetting your device. This will not erase your data stored on that device.

    • Press and hold the sleep/wake button
    • Press and hold the Home button
    • Press and hold both buttons until the display turns off and on again with the Apple logo on the subject.

    Alternatively, you can go to settings - general - reset - Reset all settings

    If that doesn't work, restore your device to factory settings. Please note that this will delete the data on your device.

    Take a look this Apple Support article: use iTunes to restore the iPhone, iPad or iPod to factory settings - Apple Support.

    If these steps do not work, contact Apple and ask for help.
