This post describes a project to place an Embest LCD8000-70T 7-inch display in an aluminum enclosure suitable for use with a similarly enclosed RIoTboard SBC.   References   Metal Enclosure for RIoTboard https://www.element14.com/community/community/designcenter/single-board-computers/riotboard/blog/2017/05/13/metal-enclosure-for-riotboard   Motivation   The Embest LCD8000-70T touchscreen display ships as a bare board with no enclosure.  A thin ribbon cable is used ...
This post describes a metal enclosure suitable for use with the RIoTboard provided you have some time and access to the proper tools.   I have been looking for an enclosure for my RIoTboard for a number of reasons:   1.  I have a tendency to inadvertently press the reset switch (S1) if I use the board in my workspace without any enclosure and attempt to move the board. 2.  My workspace is prone to static discharge for a number of reasons, and I would like to avoid frying t ...
This post documents a recent build of Android 4.3 Jelly Bean for RIoTboard on a fresh installation of openSUSE 13.2 x86_64. The build images were transferred to an SD card using Linux commands rather than using the MFGTool.   HARDWARE AND BUILD OS   Gateway NE56R12u Laptop running openSUSE 13.2 x86_64 DVD      2.1 GHz Intel B950 dual-core Pentium processor      8 GB physical RAM      135 GB /home partition for build  ...

This post documents a recent build of Android 4.4.2 KitKat on Ubuntu 12.04.5 LTS x86_64 Desktop using the Element14-provided source code for RIoTboard. The build images were transferred to an SD card using Linux commands rather than using the MFGTool.  Ubuntu 14.04.5 LTS x86_64 Desktop users should see the Addendum at the bottom of the post for additional information.   HARDWARE AND BUILD OS   Gateway NE56R12u Laptop running Ubuntu 12.04.5 LTS x86_64 Desktop    & ...
In this small guide I will demonstrate how to integrate Riotboard with Ultrasonic sensor HC-SR04 .     Step1:   export ARCH & CROSS_COMPILE to environment path.   in my case its like below, yours might be different. $ export ARCH=arm $ export CROSS_COMPILE=<PATH_TO_TOOLCHAIN>/fsl-linaro-toolchain/bin/arm-fsl-linux-gnueabi-   Step2: create a directory $ mkdir driver   create a file named "Makefile"  and replace with your KDIR value, below is ...
Hi, I know that the RiotBoard provides 3,3V on the pin header and also should provide 3,3V over the LVDS connector. What is the maximal current availible ? I would like to connect older LCD fomr a laptop and would like to know if I need extra power supply for feeding the electronics. The 3,3V current will be limited by the power regulator but I do not know which one is used by the riotboard. ...
In this guide we will be controlling a tower pro sg90 servo motor using software pwm module.     Step1: export ARCH & CROSS_COMPILE to environment path.   in my case its like below, yours might be different. $ export ARCH=arm $ export CROSS_COMPILE=<PATH_TO_TOOLCHAIN>/fsl-linaro-toolchain/bin/arm-fsl-linux-gnueabi-   Step2: create a directory mkdir driver   create a file named "Makefile"  and replace with your KDIR value, below is mine. obj-m : ...
This post describes a procedure to generate a Linux SD card image for RIoTboard using Yocto on an openSUSE 13.2 x86_64 host.  This procedure is just a clone of the excellent procedure documented by Bryan Hinton (referred to below as B.H. for brevity) with a handful of alterations to accommodate a different host OS, more modest host hardware, minor changes in the resulting Yocto build and one or two issues peculiar to my combination of hardware and software.  Bryan's document enumerates ...
Erich Styger provided an excellent description of how to connect the FTDI-based Embest  UART8000-U USB-to-TTL cable to the J18 interface on the RIoTboard in order to create a system console on a Windows host in the following post   http://mcuoneclipse.com/2014/07/21/terminal-connection-to-the-riot-board/   This post will describe how to connect a Prolific-based JBtek/Adafruit USB-to-TTL cable to the RIoTboard J18 interface in order to create a system console on a Windows host i ...
In this mini blog series we will build an IoT based intruder detection and alert system.   Blogs: Part1 : Connecting Pir Sensor Part2 : Capturing intruder image Part3 :  Email alert  <--- this blog   In previous blog we integrated a camera to Riotboard for capturing images on IR detection.   In this mini blog we will send email (with captured image) of the intruder.   now add below line to previous code (below ln30) system("python /opt/send_snapshot.py"); ...
In this mini blog series we will build an IoT based intruder detection and alert system.   Blogs: Part1 : Connecting Pir Sensor Part2 : Capturing intruder image  <--- this blog Part3 : Email Alerts   In previous blog we integrated a PIR sensor to Riotboard for human movement detection.   In this very short guide we will try to capture image once an IR detection is made.   I am using a  Logitech C310 USB camera for this purpose.   Connect pir se ...
In this mini blog series we will build an IoT based intruder detection and alert system.   Blogs: Part1 : Connecting Pir Sensor  <--- this blog Part2 : Capturing intruder image Part3 : Email Alerts     In this post we shall connect a simple cheap Pir motion sensor to Riotboard. We will be using Pir sensor HC-Sr501.       Pir Sensor HC-Sr501 has pins : VCC, GND, OUT. VCC will be connected to pin2 (5VIN) in J13 expansion port. GND will be connec ...
Intro I was inspired by Otto's blog series of getting Debian Linux on the RIoTboard: Linux on the RIoTBoard Part 1: U-Boot. However I need Ubuntu instead.   Following are the steps to get a current Linux kernel (4.1) with Ubuntu 14.04 (should work with a more current version one too).   Requirements I used Ubuntu 14.04 x86_64 to implement these instructions (actually it was a Virtual machine on VirtualBox).   Install Build dependencies: sudo apt-get install git build-essential ...
This blog post describes how I set up my RioTBoard to be a media center. I was inspired by brixtonian1970's Marine Aquarium Interface DreamBoard, and I decided to basically copy it with a RIoTBoard running Android and a compatible WiFi module. My goal was to build a media center in the garage so that I could listen to music or keep an eye on the latest football game while doing some work out there.   Installing Android There is already a good tutorial out there on how to install Android on ...
