OWI-535/SOFT USB Interface with Programmable Software for Robotic Arm Edge

Costs about $35 on Amazon

This package allows you to connect the OWI Robotic Arm Edge to a PC and have real time manual control of the robotic arm and program the arm to perform a sequence of movements.

The USB Interface Kit comes complete with a CD, printed circuit board, USB cable and accessories, and a detailed instruction manual.

NOTE: This software does not have any driver signature so you will have to disable Windows Driver Signature Enforcement in Windows 8. Anyone installing this software in Windows 8 / 8.1 please view our tutorial on “How to install unsigned drivers in Windows 8.1” https://www.sysrecon.com/operating-systems/how-to-install-unsigned-drivers-in-windows-8-1/

HARDWARE and SYSTEM REQUIREMENTS

OS: Windows XP (SP 1,2,3), Vista and Windows 7.

64-bit Windows is now supported and can be downloaded here: https://www.owirobot.com/pages/Downloads.html

How to install unsigned drivers in Windows 8.1

Microsoft did not implement Driver Signature Enforcement to annoy you. They did is to protect you from installing malicious software. This makes it a little more difficult for Rootkits to be installed on your PC. Be sure you know what you are installing!

The following steps will only last until you reboot your PC.

  1. Open Settings by clicking on your Start Screen or hitting the Windows key on your keyboard. Hover your mouse at the bottom right of the start screen until the sidebar appears. Click Settings.
  2. On the settings screen, click on Update and Recovery.
  3. On the Update and Recovery screen click Recovery.
  4. Click Restart Now under Advanced Startup.
    (Your PC will Restart into Advanced Boot Mode for this session only)
  5. Choose Troubleshoot from the Advanced Boot menu.
  6. Choose Advanced Options from the Troubleshoot menu.
  7. Choose Startup Settings from the Advanced Options Menu.
  8. Click Restart on the Startup Settings page.
    (Your PC will Restart with Advanced Startup Settings)
  9. From the Startup Settings menu choose: 7) Disable Driver Signature Enforcement.
    (Your PC will now fully boot up and Driver Signature Enforcement will be disabled for this session. Once you reboot or power down your PC Driver Signature Enforcement will be enabled.)
  10. Install your unsigned driver software. You will still get the Windows Security Alert (just click Install this driver software anyway)

Enjoy your software!

Linux: How To Identify The Linux Kernel Version?

The Kernel version is broken down into three parts:

  1. Major Number
  2. Minor Number
  3. Revision Number

The Current Linux Kernel versions (June 2014) are:

  • 3.14.5 (Stable – Maintained by Greg Kroah-Hartman)
  • 3.15-rc8 (Development – Linus Torvalds)

The first number(3) is the major revision to the Linux Kernel. The second number(14) shows the minor revision. Development Kernels are odd and production kernels are even. Development kernels are not fully tested and can be unstable. Once a development Kernel is thoroughly tested and deemed stable is will be given an even number x.1.x → x.2.x or x.3.x → x.4.x
Since the Linux Kernel is constantly being improved and revised a revision number(5) is added when smaller changes are made.

How to tell which Linux Kernel you are running?
From your Linux Terminal type:

  • uname -r
  • cat /proc/version
  • rpm -q kernel              (If you arte running Red Hat package manager)
  • dmesg | grep Linux
  • ls /boot                           (look for vmlinuz.x.x-x)

I hope this helps explain Linux Kernel versions.

Linux Commands In Windows 8.1

Basic Linux file commands working in Windows 8.1
Some commands have always been the same for both Operating Systems* but now you can use whichever you prefer when working with files. Below are a few common ones that I have verified working in Windows 8.1.

ls, cd*, pwd, mkdir*, rm, cp, mv, touch, cat, ps, head, tail, date*, whoami, finger, uname -a, du, chmod, grep, find -iname, exit*, echo*

What Is An Arduino?

The Arduino was introduced in 2005 by founders Massimo Banzi, David Cuartielles, Tom Igoe, Gianluca Martino, and David Mellis. The Arduino is not really the board itself or the microprocessor on the board. The Arduino is a hardware/software platform that was designed to provide an inexpensive and easy way for hobbyists, students and professionals to create devices that interact with their environment. The Arduino platform is completely open hardware and open source software.

Arduino boards can be purchased pre-assembled or as do-it-yourself kits. The hardware design information is available for those who would like to assemble an Arduino by hand. The current prices of Arduino boards run around $20-$30 on SparkFun and clones as low as $9 on Amazon

The Arduino platform is a single-board microcontroller designed around an 8-bit Atmel AVR microcontroller, or a 32-bit Atmel ARM. Official Arduinos have used the megaAVR series of chips, specifically the ATmega8, ATmega168, ATmega328, ATmega1280, and ATmega2560. Most boards include a 5 volt linear regulator and a 16 MHz crystal oscillator.

The Arduino platfrom feature a USB interface, 6 analog input pins, as well as 14 digital I/O pins (six of which can produce pulse-width modulated signals) which allows the user to attach various interchangeable add-on modules known as shields or basic breadboards. Many shields are individually addressable via an I²C serial bus, allowing many shields to be stacked and used in parallel. Shields or jumper wires to a breadboard are plugged into the top of the board, via female 0.10-inch (2.5 mm) headers. The Arduino has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers

The Arduino’s microcontroller is also pre-programmed with a boot loader that simplifies uploading of programs to the on-chip flash memory, compared with other devices that typically need an external programmer. Arduino boards are programmed via USB over an RS-232 serial connection implemented using USB-to-serial adapter chips such as the FTDI FT232

The Arduino Platform comes with a simple down-loadable, cross-platform, integrated development environment (IDE) written in JAVA and allows users to write programs for Arduino using C or C++. The code you write is C/C++ syntax but not a valid C/C++ program. An extra include header at the top and a very simple main() function at the bottom, to make it a valid C++ program. The IDE is derived from the IDE for the Processing programming language and the Wiring development platform and contains a C/C++ library called “Wiring”. Wiring was based on the original work done on Processing project in MIT. The Wiring IDE uses the GNU toolchain and AVR Libc to compile programs, and uses avrdude to upload programs to the board. You can program the arduino in standard C using avrstudio and upload with avrdude.

Programming in the Arduino IDE is as simple as creating 2 functions()
1. setup() – a function run once at start up that can be used to define initial environment settings
2. loop() – a function called repeatedly until the board is powered off

A simple program to blink the Arduino LED

/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.

This example code is in the public domain.
*/

// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;

// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
}

// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}


We have hundreds of tutorials in mind for the Arduino Developemnt Platform. We will begin to produce them soon so keep checking back.
