![]() I'd appreciate any help as I'm stuck here. It either doesn't read the button in the first place, or it can't translate the button press into what I want it to do. class semwait(smach.State): def init(self): (self, outcomes finished, failed) self.got False self. For the below Funtouch OS 9.0 version, go to Settings>(Dual SIM cards and )Mobile network, scroll down, and then you will find Data-saving mode. The easing animations are smooth and add a modern touch to this toggle. On top of that, its a toggle switch that comes with two labels that can be quite useful too. Putting it on its own 'listener ()' definition meant it never being executed I guess. For Funtouch OS 9.0 and higher version, go to Settings>(Dual SIM cards and )Mobile network>Data monitor), then you can restrict the apps to use data in the background. A great switch example brought by Benjamin that results in a quite beautiful toggle element by just using CSS. Toggle_topic = rospy.Publisher('/red_led', Empty, queue_size=1) I wasnt getting the values from the subscriber because it was never being called in the first place. Self.subscriber = rospy.Subscriber('button_press', Int16, self.callback) This is the code I wrote for this: class sem_wait(smach.State): ![]() The idea is for SMACH to read the button_press topic so that, if it's pressed, the blue LED is turned on, and then the cycle is repeated. The button has its own publisher topic where it posts 1 when it's pressed, and 0 when it's not. In the wait for input section, I wait for 4 seconds for the button to be pressed. Turn off red/turn on green -> turn off green/turn on yellow -> turn off yellow/turn on red -> wait for input -> repeat with sm: What I'm trying to achieve is a sort of traffic light simulator. I have an Arduino UNO with 4 LEDs (green ,yellow, red and blue) and one button. The fact that it can also free up some menu-bar space on your laptop’s small screen is a nice bonus.I'm pretty new to ROS, and I'm working with SMACH. ![]() If you frequently toggle Wi-Fi on and off-say, to prolong battery life, or for extra security while out and about-and you’ve ever wished you could do so using the keyboard, Airtoggle is a handy utility. And few people will tax Airtoggle of SystemUIServer this way. There is also a way to turn it off from the command line. The app has a free trial period and if it works you can purchase for 3.00. Maybe this will enable you to turn it off. Abstract: Previous research on consistent updates for distributed network. There is a 3rd party app called Bluetoggle that lets you set up a hotkey to toggle Bluetooth on and off. Of course, SystemUIServer automatically relaunches if it crashes, so there was no harm done. Blueswitch: enabling provably consistent configuration of network switches. ![]() Two of the times I put Airtoggle through this (admittedly non-real-world) test, it caused SystemUIServer, the OS X background process that handles menu-bar apps and menu extras, to crash. While testing the program, I used the Airtoggle shortcut to quickly toggle Wi-Fi on and off multiple times. The only other issue I had with Airtoggle was one that likely won’t affect most users. If you prefer that it reside farther to the right, you’ll need to manually move it. One drawback of this feature-and it’s not something the developer can control-is that whenever you turn on Wi-Fi, the menu extra appears as the left-most of the stock (Apple) menu extras. In other words, if you’re not using Wi-Fi, you won’t see its status menu. The device accepts up to 3 switch inputs and allows users to. Alternatively, a nifty Airtoggle option can automatically hide that Wi-Fi menu whenever you disable Wi-Fi, and display it whenever Wi-Fi is on. BlueSwitch is a switch interface that converts standard wired switches to wireless Bluetooth ones. For many people-especially those using laptops with crowded menu bars-the best part of Airtoggle is that you can easily disable and enable Wi-Fi without having to keep Apple’s Wi-Fi menu extra enabled.
