由 浪尽此生 提交于 2019-12-23 17:26:04
问题 I am having some difficulties in understanding how to decode a Bell 202 encoded signal. How do I do that? I know Bell202 encodes binary data with ones and zeros as 1200 Hz and 2200 Hz. I recorded a radio signal on 145.825 Mhz with a 2Mhz sampling rate when the International Space Station (ISS) transmitted APRS. I uploaded a Python Numpy NPY file here https://drive.google.com/drive/folders/0B-6iySZt3rrjQVdpRHBOc2lyQTQ and it has 4 data streams in it. Don't be confused, I just recorded the same

问题 I've got some rough-and-ready code that allows me to filter some results based on two radio buttons. I'm struggling to add a third variant that will serve as a 'show all', ie to display all four divs at once. Any help would be much appreciated. <p class="text1">Variants <label> <input type="radio" name="type" value="variant-2" id="type_0" checked="checked" /> Variant 1</label> <label> <input type="radio" name="type" value="variant-1" id="type_1" /> Variant 2</label> </p> <script> $(document)

Only one (the first) radio button in a group is selectable / active

由 谁说我不能喝 提交于 2019-12-23 04:36:35
问题 I have a few groups of radio buttons being generated using data from a database. Currently I am only able to click on / successfully select the first of these groups of radio buttons, the others are unresponsive. The code when I test it separately in jsfiddle works fine, so I don't think it is that, however here it is anyway HTML generated/source: <div class="radio"> <div> <input type="radio" id="a" value="A" name="Q1" /> <span class="inline">A</span> </div> <div> <input type="radio" id="b"

Show current song information from html5 audio stream (in Meteor app)

由 女生的网名这么多〃 提交于 2019-12-22 09:22:21
问题 I'm working on an HTML5 radio player in Meteorjs. See http://radio.meteor.com/ or http://github.com/guaka/radio-meteor I want to display the song that's currently playing. How can I do that? I'm not sure if resorting to server side would be a great idea as the server would have to fetch metadata for a growing number of streams (I want to allow people to add more channels). Browsers compatibility is not that much of an issue, as long as it will work in Phonegap. I don't care about all browsers

How to programmatically select RadioButton in an activity

问题 In my project, I get the value of the gender from the database as 0 and 1. 0 for male and 1 for female. Based on this values, I need to check the corresponding RadioButton in a RadioGroup. If 0 is pressed, radio0 will be checked or radio1 will be checked. I don't know how to check the radio button based on this string values... This is the code I tried: String gendd=ViewProfileActivity.participantview.get(4); System.out.println("Gender:::::"+gendd); male=(RadioButton)findViewById(R.id.radio0)
