GET request using Azure app services and Intel Edison

阅读更多关于 GET request using Azure app services and Intel Edison

问题 I wanted to read data from an azure app service's easy tables using REST API to an Intel Edison. Before I did the same using Azure Mobile Services and my code was this. PS: I'm programming the device by the Arduino IDE. void send_request() { Serial.println("\nconnecting..."); if (client.connect(server, 80)) { // POST URI sprintf(buffer, "GET /tables/%s HTTP/1.1", table_name); client.println(buffer); // Host header sprintf(buffer, "Host: %s", server); client.println(buffer); // Azure Mobile

问题 I am trying to install XFSTK in Ubuntu 16.04(64 bit). I followed XFSTK to install this package. While building package, it throws This Error. INPUT : libusb is already installed in /usr/lib/x86_64-linux-gnu/libusb.a. I created symlink in /usr/lib/, It threw Linking error (ld). So how can i install xfstk on 64 bit Ubuntu 16.04 ? 回答1: The prebuilt images for xfstk worked, And for libboost_program_options.so.1.62.0 lib, I had to install libboost-all-dev package. And finally u-boot console came

yocto fails to build images for intel edison in ubuntu 17.10(64 bit)

问题 I am beginner to yocto. I am trying to build edison images on ubuntu 17.10. I am following this link. But It fails in native autmake. I have linked recipe ERROR over here. RE-EDIT I have made changes for removing automake error, followed by patch. Now it's failed in native ncurses-5.9. Log file is attached Log_file. Thanks, Pritam 回答1: Something wrong with generation man docs for automake in the command line: : && /bin/mkdir -p doc && { PATH='/home/prityaa/documents/boards/intel/edison/tools

An efficient way to do basic 128 bit integer calculations in C++?

阅读更多关于 An efficient way to do basic 128 bit integer calculations in C++?

Some years ago I needed a way to do some basic 128 bit integer math with Cuda: 128 bit integer on cuda? . Now I am having the same problem, but this time I need to run some basic 128 bit arithmetics (sums, bitshifts and multiplications) on a 32 bit embedded system (Intel Edison) that does not support 128 bits of any kind. There are, however, 64 bit integers supported directly (unsigned long long int). I tried naively to use the asm code that was answered to me last time on the CPU, but I got a bunch of errors. I am really not experienced with asm, so: what is the most efficient way, having 64

Node.js: How to programmatically determine asynchronous?

阅读更多关于 Node.js: How to programmatically determine asynchronous?

I'd like to be able to take a function that doesn't take a callback and determine if it will execute asynchronously. In particular, I'm working with Node.js on the Intel Edison using mraa , and it has native C++ implemented functions like i2c.readReg(address) that doesn't accept a callback. How can I determine if a function is blocking the processor for other system processes? How can I determine if other JS can run in the interim? Or am I not even approaching this the right way? You can't really determine asynchronicity programmatically. It should be clear from the API presented because if it
