问题 We are working with Android Things on Raspberry pi 3, everything works great, recently we got an NXP board called OM5578/PN7150, basically to use NFC efficiently. Through NXP guide (AN11690 NXPNCI Android Porting Guidelines) I need: Add the drive in the Kernel Customize the AOSP (Android Open Source Project) I would like to know: Which version of the kernel is best for recompiling by adding the drive with Raspberry pi 3 support Which version of AOSP is recommended for Raspberry pi 3 in kiosk

问题 I've tested Android Things 0.4.1 image which I've downloaded before builds moving into console on RPI3 successfully but every image I've build with Android Things Console with empty bundle failed to boot even image 0.4.1 I've build with Android Things console failed to boot, Here is serial console error: U-Boot 2017.07-03124-gc35995ad17 (Aug 18 2017 - 02:52:42 +0000) DRAM: 944 MiB RPI 3 Model B (0xa22082) MMC: mmc@7e300000: 0 reading uboot.env In: serial Out: serial Err: serial Net: No

问题 I'm using Pimoroni Rainbow-Hat Raspberry pi3 kit. I have loaded android things image on sdcard. I have power cable and ethernet cable connected. I can see Android things boot screen on display but i don't see the IP. When i try to connect with adb connect Android.local it's not working(getting unknow host). I tried the ethernet cable from pi3 ethernet port to laptop , i can see the lan ip when i do ipconfig /all but when i try adb connect <-ip-:5555, still connection gets refused. but am able

问题 I have a Raspberry Pi 3 with Android Things running on it, and I'm trying to write an application that makes use of UART serial. I used the sample code in Android Things documentation for sending data, and it worked perfectly, but the code supposed to receive data returns empty bytes. while ((count = uart.read(buffer, buffer.length)) > 0) { Log.d(TAG, "Read " + count + " bytes from peripheral"); } There's an interrupt for when the UART buffer gets some data in, and that gets triggered calling

问题 I have a very simple project, in which I aim to be able to toggle an LED by means of a direct method call (through Azure IoT hub) on my Raspberry Pi 3, running Windows 10 IoT Core. In it's current state, the program I wrote shows only a white box with an x in it, not unlike a mail envelope, and the back end light-controlling code does not respond to direct method calls. However, when connected to a Visual Studio 2017 remote debugger, the code behind the UI seems to run perfectly fine (or so I

问题 Can someone please help me in setting up my RPi 3. I'm tying to build a speech to text / speech recognition with my gaming headset (Creative Technology, Ltd Sound Blaster Tactic(3D) Sigma sound card). The speakers are now working but unfortunately I'm stuck in setting up the mic. Before i tweaked the settings, I can record/create a wav file but whenever i play the wav file there's no sound. After changing some settings, i'm encountering new error below. Thanks in advance! Error: pi

问题 Since I found no answer for my question, neither in older posts nor in other forums, I want to ask the stackoverflow community for advice. I am using a raspberry pi 3B+, version 9.4 (lite) with kernel version 4.14.71-v7. I use python3.6. I installed it as follows: sudo apt-get install build-essential checkinstall sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev cd /usr/src sudo wget https://www.python.org/ftp/python

问题 I am new user to the Raspberry Pi 3. How much space is required to install OpenCV on Raspberry? 回答1: Installing OpenCV on your Raspberry Pi can be done in two ways, both having different space requirements: You can use the Debian repositories with the sudo apt-get install libopencv-dev command. This is the easiest way to install OpenCV on your Pi, and also takes the least amount of space (if that's a concern for you). It will take around 80M when installed. The downsides of this approach is

问题 Is TensorFlow supported on Android Things? Can TensorFlow Android samples be ported to run on Android Things? If so, what’s the simplest way to do it? 回答1: The short answer: Yes, you can indeed run TensorFlow on embedded devices running Android Things such as Raspberry Pi 3. We have ported the TensorFlow image classification app to Android Things. It is available at: https://github.com/androidthings/sample-tensorflow-imageclassifier. The long answer: In order to run TensorFlow you first need
