Raspberry Pi
While much attention has been focused on the built-in WiFi hardware, the Raspberry Pi 3 (1) also ships with on-board support for Bluetooth. Bluetooth is a wireless technology for exchanging data over short distances using 2.4 GHz radio signals.When running the recommended Raspbian Linux…
BlogIn this post I'll discuss the new offering from the Raspberry Pi Foundation, the Raspberry Pi Pico. It is an interesting product that combines two technologies of great interest: the Raspberry Pi and microcontrollers.What is a Microcontroller?A selection of microcontrollersICS is currently running…
BlogIntroductionIn this post we'll look at the Raspberry Pi camera module, a low cost hardware module that supports still picture and video recording and is the first official hardware add-on for the Raspberry Pi. We'll also look at the camera's features and specifications, how to set it up…
BlogLet's continue our blog series on ARM assembly language by drilling down into some of the basic ARM machine language instructions.Instruction Formats and Addressing ModesARM instructions accept from zero to three (and occasionally more) operands. An optional S suffix can be added to indicate that…
BlogSome carrier boards used with System-on-Modules (SoMs) include an onboard EEPROM (electrically erasable programmable read-only memory) that helps the bootloader identify the correct device tree to load. The catch? That EEPROM often needs to be programmed before the board can even boot, creating a…
BlogFor many decades writing software in high-level languages has been the norm, and more recently even low-end microcontrollers are almost exclusively programmed in languages like C and C++.Of course, the native language of processors is machine code, and ultimately all programs need to run as native…
BlogIn part 2 of our series on GPIO programming, we look at the hardware capabilities of the Raspberry Pi's GPIO interface. As you probably know, the Raspberry Pi is a family of low cost single-board computers developed primarily for education by the non-profit Raspberry Pi Foundation. To date…
BlogThinking of building large gameshow-like interactive experiences? Want to use your Raspberry Pi to talk to your computer? Interested in integrating custom controllers with your games? If so, this blog is you. We were tasked with creating an interactive experience — a Plinko-like game…
BlogThis is a HOW TO guide for building Qt 5 for the Raspberry Pi, and building and deploying Qt 5 apps using Qt Creator. This guide will be using Raspbian "Wheezy", a Debian based distro designed for the Raspberry Pi. This guide also assumes the use of Linux or UNIX on the workstation side. Note:…
BlogThis week was another slow week as many people were off part of the week due to New Year's or extended holidays. PhoneGap, recently renamed to Apache Callback, is now being renamed as Apache Cordova. There is discussion on the mailing list about where the code repositories will reside. It may…
BlogThis week we did some marketing to promote the project. I made a posting to the callback developer mailing list and we put a link to this blog from the ICS web site. Quim Gil of Nokia kindly made a posting to the Nokia Qt blog. I also recorded a podcast with Mark Hatch…
BlogThis week we finished implementing some Cordova APIs (at least for the Qt 4 version). Compass and Accelerometer are done and some of Events was implemented. Notification is done as is most of File support and we are starting work on Contacts and Camera.Note that I am going to start consistently…
BlogSince the last posting we properly set up deployment of Cordova Qt for MeeGo Harmattan (e.g. the Nokia N9 phone). We also got Qt 5 packages including WebKit built for MeeGo Harmattan and tested it on a Nokia N9. Incidently, a big PR1.2 software update rolled out this week for MeeGo Harmattan phones…
BlogThroughout this project one thing that has been constantly changing has been the source code repositories, both due to several project names changes and with the move to being run as an Apache project. This last week the old repository at http://github.com/cordova/cordova-qt was removed and…
BlogWork has been slowing down somewhat as Qt 5 has been firming up for release. The Qt 5 alpha came out on April 3rd and we tested our code with it. Work is moving ahead for a Qt 5 beta release and then the 5.0.0 final this summer. Qt 4.8.1 also came out and we tested Cordova Qt with it. A 4.8.2…
BlogWe've recently been running the Cordova tests and making some fixes to get them to run better. We've documented on the Wiki how to run the Cordova tests. See the section "Running Cordova Tests" at this wiki page. We hope to have a demo video up soon showing the tests running on the…
BlogAbout three weeks ago, Nokia arranged for ICS to gain access to the Raspberry Pi board so that we could help with an exploratory open source effort to get Qt working on this platform. That is how I got my chance to hack some code for this amazing board. The idea was to get a bleeding edge version…
BlogGood talking to you all at Qt Dev Days Munich. We'll be at Dev Days in San Francisco beginning Nov 29 - hope to see you there!
BlogHere's a video of my colleague, Roland Krause, demonstrating Qt 5 + Raspberry Pi at Qt Dev Days in Munich. Stop by our booth in San Francisco next week to see it first hand...and for your chance to win one of your very own!
BlogAs part of the initiative to put Qt 5 on Raspberry Pi, ICS gave away over 70 Raspberry Pi boards to interested developers at Qt Developer Days last week. If you were one of the lucky winners, be on the lookout over the next few days for an email from ICS so you'll know how to go about receiving it…
BlogThe Raspberry Pi folks report that the first batch of production boards is finally in production. The first 10,000 units should start becoming available around the end of this month. ICS should be getting a number of boards from this first batch which we will distribute among our developers. The…
BlogThe Raspberry Pi boards are now shipping in volume from the distributors and unboxing videos are showing up all over the Internet. If you were one of the winners of a board from ICS you should have received an e-mail today with the details on how to redeem your voucher. If not, check your spam…
BlogWe haven't blogged here for some time, in part because many of the folks at ICS have been very busy planning and preparing for the annual Qt Developer Days conferences in Berlin, Germany and Santa Clara, California. We had some coverage of the Raspberry Pi and Qt at the recent Qt Developer Days in…
