问题 I'm working on an electronic phone-line emulation for a raspberry pi. For this, I’m in need of a function, which is called each 20 ms (=50Hz, half of the ringing voltage-frequency), checks the electrical current and updates the duty-cycle of a HW PWM. To get there, I set up a signal-handler on an according timer (as I’d hang it into the scheduler in a pure embedded environment) and let it do its work. Note, that the code below is shortened just in order to kfocus on the issue. This already

问题 I am developing an app for android that measures some network parameters every hour. I already have the code to do the measurements, so I only need some help on how to make it do it periodically. What should I use? Timers, Alarms or something else? Do you have any easy example on how it works? Thanks for your help! 回答1: The only good answer is to use AlarmManager . Having a service that sits for an hour waiting for the hour to pass is ridiculous. 回答2: Using a service (so that you're not tied

问题 I was reading about how the alarm() call works on the linux. alarm(5) would send a SIGALRM in a minimum of 5 seconds to the process which has made this call. The alarm is caused at that moment thanks to a down counter which is set by the kernel reaching zero. My doubt is here - we can have N number of processes which make an alarm call, and there is one down counter in the system available for this purpose. So the kernel has to keep track of all the processes it has to send a signal to, with

问题 I'm a bit confused on iPhone's capabilities for alarms (local notifications) and I haven't found a clear answer yet. I would like to create functionality like the alarm clock (or even new mail). Specifically, if the device is asleep, it gets waken with a buzz or sound. A popup message that you can't see (because the device is asleep) is a lot less useful. But, it seems that using the UILocalNotification service, this doesn't seem to be happening. I haven't checked out push notifications, but

问题 I am writing a social cloud game for Android and using PHP on the server. Almost all aspects of the game will be user or user-device driven, so most of the time the device will send a request to the server and the server will, in turn, send a response to the device. Sometimes the server will also send out push messages to the devices, but generally in response to one user's device contacting the server. There is one special case, however, where a user can set a "timer" and, after the given

问题 I'm creating an alert pager app by using Ionic(v1) framework, which the notification message is very important for user, and they don't want to miss it. However the normal android / ios notification can only display the message on the screen + play notification sound once, which user always miss the messages. Anyone can suggest if there's any way that can generate the notification similar to in-coming call or clock alarm, it can ring forever until user acknowledge the message by pressing the
