Setting sensors (location) in headless Chrome

由 不想你离开。 提交于 2020-06-15 18:36:04
问题 Is it possible to set custom location coordinates with Chrome Headless? I can't find it in the Devtools protocol API. Is there a workaround available? 回答1: I googled it and got many methods. I try one by one, almost all of them turn out outdated. Then I find out a solution, use chrome devtools protocol to achieve that. The small example code below, that it uses the most common tool selenium to execute chrome devtools protocol command. import time from selenium.webdriver import Chrome,

过去包括将来，从别人开源项目上和博客学到太多，实在是很欣赏开源的精神。这段时间，review了下做过的东西，毕业后不再做这个方向的东西了。陆续也有不少网上或者低届的同学问我讨要论文相关资料，现在把读研期间做的东西的资料、源码开源出来，全部放到github上 https://github.com/changety/hellowsn ，供参考，也为纪念自己读研期间花在它们上的时光。六月是新的旅途。这里贴一下readme文件和相关图。 Wireless Sensor Networks(WSN) Monitor System Based On Android 包括三部分: ZigBee协议 实现的WSN，由ZigBee协议的传感节点组成，完成数据采集、处理、上传，执行控制命令。 项目文件 JavaWeb实现的服务端，由RS232通信，数据解析，持久化层，面向移动终端的Web通信等模块组成。web部分包括了HTTP及XMPP协议的推送服务。 项目文件 Android平台上的WSN监控软件。 项目文件 WSN部分: 硬件基础 兼容 TI CC2530DK 的所有CC2530评估板上 运行 ZigBee协议 协议栈 Z-Stack协议栈 的CC2530芯片节点 软件实现 构建于基于 ZigBee协议 实现的 Z-Stack协议栈 上，在AP层上实现所有功能逻辑。 部署方法 熟悉IAR以及Z

How to Use I2C with XC16 Using MCC - Microchip

由 走远了吗. 提交于 2020-03-05 04:58:49
问题 This is the first time I've attempted to use I2C for my design so bear with me. I've used the MCC to set up I2C and I have I2C.c and I2C.h. I'm trying to read a pressure sensor value. The value is 15 bits long. Do I need to write to the slave before I read or can I just read the value straight away? I've put part of my code below. You can see that I'm only trying to read a pressure value. Can anyone point me in the right direction of how to achieve this? Thanks guys. NOTE: Using a

How to use onAccuracyChanged function in sensors

由 不打扰是莪最后的温柔 提交于 2020-01-26 02:54:10
问题 I am making an app in which am using two sensors. TYPE_MAGNETIC_FIELD TYPE_GRAVITY I initialized the respective sensors and then in onSensorChanged function, am fetching the data and doing the calculations on the same. I have one simple question, how can I use onAccuracyChanged function to filter out data? I want the data with medium and high accuracy!! I printed basic statements to see what kind of accuracy am getting while debugging the app. Code : `@Override public void onAccuracyChanged

PROXIMITY_SCREEN_OFF_WAKE_LOCK not working with Samsung

由 眉间皱痕 提交于 2020-01-16 18:07:51
问题 I am using the Proximity Sensor while webRtc call in android to turn screen on/off using device sensor. It is working perfectly in most of the devices but not in Samsung. When Sensor turns the screen off onStop() of the activity is called. Following is the code I am using : @Override public void onSensorChanged(SensorEvent sensorEvent) { if (sensorEvent.sensor.getType() == Sensor.TYPE_PROXIMITY) { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { if (mWakeLock != null) { mWakeLock

Mahony's algorithm - Yaw angle becomes unstable when rotating device fast

由 寵の児 提交于 2020-01-15 12:23:50
问题 I'm newbie in sensor and IMU so my question is probably very basic for others, but it's already puzzled me for days. I'm using Mahony's algorithm to calculate Euler angle of my device; the three angles looks correct when put the device static or move/rotate the device slowly; however, the Yaw angle will become unstable and incorrect if rotating the device fast. Could someone help me solve this issue ? My device uses MPU-9150, I use the 6 parameters method of Mahony algorithm, that is to say,

How to convert a program that uses SensorListener to SensorEventListener

由 吃可爱长大的小学妹 提交于 2020-01-13 06:08:09
问题 I am creating an application named CompassApp. I have created two classes named Compass.java and Rose.java. This application has been created from a tutorial described in a website and this uses the deprecated version of SensorListener. The class Compass.java is using this deprecated version. The app worked fine when I used the deprecated version. Then I thought to convert my app into the current version that is SensorEventListener. But the rotation of the compass stopped! I'm stuck and don't

How to know if my SensorManager has a registered Sensor

由 南笙酒味 提交于 2020-01-12 07:48:25
问题 I'm using a sensor for my Android Application. I register the sensor with a line of code: mySensorManager.registerListener(this, orientationSensor, SensorManager.SENSOR_DELAY_NORMAL); I have introduced a line of code to unregister the listener so it wont be running all time: mySensorManager.unregisterListener(this); So far it works, but i need to register it again when the application resumes. I need to know if my sensorManager has a registered listener so I can registered again or skit it.
