MicroView is a Tiny Arduino Compatible Board with an OLED Display (Crowdfunding)

Last year, we’ve been presented with many small Arduino compatible boards such as MicroDuino, RFDuino, BLEDuino, Spark Core, Olimexino-Nano and more… All these boards have been own strength and connectivity options, but if you want to see what going on in your board, you’d either need to connect it to your computer, or connect some LEDs or an external display. Geek Ammo’s MicroView fixes that by providing an Arduino compatible board nicely combined with a built-in OLED display. This allows you to display stats, weather, play games, create wearable projects (watch, necklace), and all sort of other projects that may require a small display. MicroView specifications: MCU – Atmel ATmega328P @ 16 MHz with 32KB flash, 2 KB SRAM, and 1KB EEPROM Display – 64×48 OLED Display Digital I/O – 12 (of which 3 provide PWM output) Analog Input – 6 Operating Voltage: 5V Input Voltage: 3.3VDC to 16VDC, no power regulator needed Breadboard friendly standard DIP package A USB-serial […]

Free Online Courses & Workshops For ARM Cortex-M Microcontrollers

STMicroelectronics and Digikey are co-sponsoring an EE Times University online training course entitled “Fundamentals of Microcontrollers (MCUs): Hands-On Workshop”. The first two 45-minutes sessions will be theoretical and provide and overview of micro-controllers, and explain methods to select an MCU for a given project. The first 1,000 persons based in the US or Canada, who attended the first 2 sessions, will receive a free STM32F4 Discovery Board (ARM Cortex M4). The three next sessions, conveniently taking place about a week later, hopefully after you’ve received your board, will be an actual workshop with STM32F429 Discovery Board. Here’s the detailed schedule for the training: December 2, 2013, 12PM (Eastern Time) –  Session 1 – Introduction to Microcontrollers Common microcontroller architectures Pipelining Peripherals: Timers, Communication, Analog December 3, 2013, 12PM (Eastern Time) – Session 2 – Selecting the Right Microcontroller 10 Steps to Selecting a microcontroller What to look for in a development kit Tool setup lab December 11, 2013, 12PM (Eastern […]

Texas Instruments Releases Android App for SensorTag and Publishes Bluetooth Low Energy Training Videos

Texas Instruments Sensortag is a Bluetooth Low Energy (BLE) development kit with 6 sensors (IR temperature, humidity, pressure, accelerometer, gyroscope, magnetometer) mainly destined at mobile application, which I recently tried in Linux. Until now, only it was only officially supported in iOS and Windows, but a few days after the release of Android 4.3 which adds Bluetooth Low Energy support, Texas Instruments quickly worked to release an Android App for their BLE devkit. The annoying part is that the Android app is only available as a Windows executable (SensorTagAndroidApp-0_9_0-windows-installer_2.exe), so you’ll have not choice but to use Windows to uncompress the files. Yet the installation goes as follows: Copy the SensorTag.apk file (SensorTag_0_9_0.apk) to your Android 4.3 device Enable installation of apps from unknown sources (Settings -> Security -> Device Administration -> Unknown Sources) Open file manager and launch, locate the .apk file and install the app by clicking the .apk file. I haven’t got Android 4.3 devices, so no […]

Training courses will focus on topics such as Network Security, Incident Response, Web Application Security, and Exploit Development. Connectivity and Networking – The Connectivity and Networking track educates design engineers on wired and wireless communications, spanning need-to-know topics from essentials of USB device development to antenna and RF system design. Debugging and Test – This track features a mix of lectures […]

Embedded Android Training Workshop At Linaro Connect Asia 2013

Karim Yaghmour, Opersys’ CEO, gave 4 training sessions dealing Embedded Android at Linaro Connect Asia 2013, in Hong Kong, earlier this month. Charbax filmed those 4 40 to 50 minutes session with excellent video and audio quality, so I encourage you to watch all sessions if you are interested in this topic. The presentation slides are available on Slideshare. The first training session is entitled “Android Internals”, and Karim introduces Android’s overall architecture, following the agenda below: Android Concepts Framework Intro Overall Architecture System startup Linux Kernel Hardware Support Native User-Space Dalvik JNI System Server Calling on Services Activity Manager Binder HAL Stock AOSP Apps Case-in-Point The second session “Working with the AOSP” deals with the following key points: Tools and location Content Building Build tricks Build system architecture Output images Using adb Custom toolchains and dev kits Compatibility Test Suite Basic hacks The third session entitled “Native Android user-space” gives details about Android “rootfs”: Filesystem layout Architecture vs. filesystem […]

AnDevCon IV Classes and Workshops Schedule

AnDevCon is a technical conference for software developers building Android apps, and the fourth Android developer conference will take place in San Francisco on December 4-7, 2012. The organizers have already listed the schedule, including details about the workshops and classes which will take place at the conference. The 4th of December is reserved for workshops, and the other 3 days can be spent on shorter classes. All workshops will provide sample code, as well as most classes, excluding the overview session and business related sessions. There will be three full day Android workshops: Android Development Boot Camp – Hands-on introduction to Android application development and the tools essential to the process. Beyond an introduction to the basics, this workshop also covers some of the common hurdles met with development, and how to overcome them. You will also have the opportunity to build an Android app of your own where you can apply what you learn in the workshop. Building […]

Using OpenOCD JTAG in Android Kernel Debugging – Android Builder Summit 2012

Mike Anderson, CTO and Chief Scientist for The PTR Group, gives a tutorial about Linux kernel debugging in Android with OpenOCD JTAG at the Android Builder Summit in February 2012. Abstract: Owing to the use of the Linux kernel, Android device drivers can be debugged using many of the same techniques as Linux. Still, much of the user-space interface code typically found in Linux is missing in Android. This complicates the debugging of kernel driver code. This presentation will demonstrate the use of the open on-chip debug (OpenOCD) software and an inexpensive JTAG to debug Android kernel code. The target audience for this presentation are platform developers looking to debug their kernel code such as device drivers. This presentation is targeted at intermediate-level developers with some understanding of kernel code development. You can also download the presentation slides on linuxfoundation.org website.

Android Device Porting Tutorial – Android Builder Summit 2012

Benjamin Zores, Open Source Software and Multimedia Architect at Alcatel-Lucent, gives step-by-step to port Android to your own device at Android Builder Summit in February 2012. Abstract: This talk is presented as a step by step tutorial meant for Android platform rookies, as to discover all Androidisms one has to tackle down to bring his own custom device to life. Based on a real-life Android 4.0 ICS device porting experience, the talk will cover early board bringup (from U-Boot and Fastboot to Linux kernel and drivers), AOSP device integration, Android-specific device init customization, touchscreen input layer adaptations and Hardware Abstraction Layer (HAL) driver interfaces development.
