timer

问题 I am using an Atmega328p-pu. I am trying to use the timer 1 for both a 16 bit PWM as well as using the overflow inturrupt to increment a timer. My code is below, I also set the F_CPU to 8000000UL in the make file. I would like the to have a variable that counts up for a defined amount of time and then resets and continues. so far I would expect it to count up for 7.5 seconds. I believe I should have a clock frequency of 8 MHz, then with fast PWM with a 1 prescaler and ICR1 at 5000 I would

问题 Basically what I'm trying to do is to make a picture box go up, then left, then down, then right, all based on timer ticks. I'm fairly new so I don't really know what's wrong. If you guys could give a simple answer or a better approach, that'd be great. Dim slides As Integer slides += 10 If slides < 20 Then PictureBox1.Left += 10 ElseIf slides > 20 AndAlso slides < 40 Then PictureBox1.Top += 10 ElseIf slides > 40 AndAlso < 60 Then PictureBox1.Left -= 10 ElseIf slides > 60 AndAlso < 80 Then

问题 basically, I have a keylistener code (I am aware of keybindings thank you but I don't need that for my project), and it will re-size the window frame based on what you press. However, when you hold down w, it goes like this w [pause] wwwwwwww and it's noticeable whenever you re-size the window. Can someone help me successfully put timer in my code? I've excluded the import statements but they're all there. public class KeyFrame extends JFrame implements KeyListener { public boolean t = true;

问题 I have a stream of numeric values that arrive at a fast rate (sub-millisecond), and I want to display their "instant value" on screen, and for usability reasons I should downsample that stream, updating the last value using a configurable time interval. That configuration would be done by user preference, via dragging a slider. So what I want to do is to store the last value of the source stream in a variable, and have an auto-retriggering timer that updates the displayed value with that

问题 Hello I am kind of new to C#... I have a picturebox which is my control. It's meant to be rapidly clicked on. I want to make it so when it is clicked a certain amount of times a second picturebox which has a .gif in it becomes visible. And when a certain amount of time has past without clicking the first picturebox the second disappears. Is there a way to do this? Maybe with timers. Some sample code will help me out A LOT! Thanks to all in advance! :) 回答1: Try This: System.Windows.Forms.Timer

问题 Basically, I have an angular application, and I would like to have (change) only be triggered after a few seconds of nothing happening. Therefore instead of sending requests every time a letter is written in an input field, only after writing a letter and nothing happening for a few seconds, then the request would be sent. 回答1: You may use rxjs debounceTime piped to the valueChanges observable of the reactive FormControl as in the example at https://stackblitz.com/edit/angular-debounce-form

问题 I am currently running a function at regular interval round the clock. setInterval( function(){ do_this(); } , 1000*60); Unfortunately, this is not exactly what I want. I would like this function to be run at set regular interval from morning 0900hrs to 1800hrs only. The function should not run outside of these hours. How can this be done in node.js? Are there convenient modules or functions to use? 回答1: You can simply just check to see if the current time is within the desired time range or

问题 I am building a progressive web app using React, the concept of which revolves around keeping a timer running. For context, the app is for home-brewers to keep track of when hops and other additions need to be added to their boil during their brew. Additions are added with a certain amount of time remaining in the boil, i.e. 1 oz Citra hops at 20 minutes remaining. I'm using JavaScript's setInterval to "tick" the timer, which is an elapsedSeconds state property that drives the rest of the
