NERP Tonight: Ste on the Launchpad

Tonight at NERP, Ste Kulov will introduce the MSP430 line of microcontrollers from Texas Instruments. His talk will focus on using the MSP-EXP430G2 Launchpad kit.

The MSP product line from Texas Instruments contains an extensive variety of microcontrollers varying in size, peripherals, etc. MSP microcontrollers are know for being 16-bit, very low power, feature-rich, and low-priced. The development boards are called Launchpads. Open source software for developing on Launchpads has been scarce and not condoned by TI. This is changing however as TI has joined the msp-gcc project in collaboration with Redhat. One outcome to date is the energia development tools, which are a fork of the Arduino tools.

http://energia.nu/Guide_MSP430LaunchPad.html (see the pix of Launchpads)

Here’s what Ste says he’s likely to cover. (It’s a lot, so we may run a little over time).

1.) Talk about the MSP-EXP430G2 Launchpad kit and what comes with it.

2.) Very brief overview of Energia, which is software that turns your Launchpad into an Arduino.

3.) Introduce Code Composer Studio, which is the official software used for most Texas Instruments software development.

4.) Basic Boolean algebra review.

5.) Go over simple tasks such as setting, clearing, and toggling bits.

6.) Run a simple “Hello World” LED blink program.

7.) Run through the project I had to create for my job.  It uses Timers, Interrupts, and the Low Power modes.

NERP: Implementing MIL-STD-1553 with 3 Beagles

Tonight Trefor Delve will present a distributed simulation development making use of three Beagle Bone Blacks as part of the network. The simulation is used as a proof of concept for a general purpose, configurable simulation platform making using of public domain software.

Mil1553_timingMIL Standard 1553 bus timing [wikipedia]

The presentation will introduce the principles of the MIL Standard 1553 data bus, show a simulation with simulated hardware and demonstrate the same software running on distributed Beagle computers making use of the Beagle’s ADC, PWM and SPI interfaces.

The presentation will also demonstrate the use of the QT widget set to allow remote virtual hardware to interact with the Beagle simulation.

The presentation will demonstrate the setup of the ADC, PWM and SPI interfaces using the system capabilities.

NERP Tonight: QT and Steppers

NERP Tonight: QT and Steppers

 

Tonight at NERP, we’ll have a show and tell about the PS:1 entry in the Element14 hackerspace challenge.(http://www.element14.com/community/community/knode/single-board_computers/next-gen_beaglebone/blog/2013/06/12/beaglebone-black–the-2013-hackerspace-challenge/)We’ll highlight use of the QT framework and gui tools on the Beagle Bone Black to run the stepper motors on the pick and place machine. There are always challenges in getting a new platform up. One challenge has been resolving version problems with the QT3 to QT4 transition on ARM. We’ll find out how that’s going. Also we’ll also have a tour of the system’s Z- and θ- axes mechanism and find out what the test results were on using some very small stepper motors to drive the head. As a bit of improvisational comedy, some of the tests will be done live during NERP! Yow!

NERP: Retro DOS Gaming on the Raspberry Pi, and a Hackerspace Challenge Update

Tonight at NERP,  Jay Hopkins will show us some how to set up an MSDOS emulator and use it to run 8-bit games. Bleep.

Ed will talk about the status of PS:1’s project for the Element14 Hackerspace challenge. While amusing, entertaining, and informative, the update will also be a pitch for anyone who is interested in the technologies to help PS:1 compete for the big prize.

Programming in Erlang -plus- Making an Xbox Media Center on the Raspberry Pi

Tonight at NERP, we’ll have two presentations.

Brian Chamberlan will tell us about using Erlang to program/control the RaspberryPI/BeagleBone. Erlang is a functional, general-purpose concurrent, programming language and runtime system. Erlang provides language-level features for creating and managing processes with the aim of simplifying concurrent programming. Processes communicate using message passing instead of shared variables, which removes the need for locks. [paraphrased from wikipedia]

Michael Beck will show us how to set up Xbox Media Center, XBMC on the Raspberry Pi. Pretty much every possible mode of interacting with a digital media stream is supported by XBMC. The Raspberry Pi’s excellent (but proprietary) video rendering hardware makes it an ideal platform for building a home media center.

Raspberry Pi Video Camera, BoneScript on the Beagle

Raspberry Pi Video Camera, BoneScript on the Beagle
NERP is not exclusively raspberry pi, the small computer interest group atPumping Station:One in Chicago.

We’ve been wondering what it’s like to work with the new Raspberry Pi camera module. Tonight we’re in luck. Craig LeMoyne has a Raspberry Pi project he’ll show us tonight. In his words:

“I have an RPi Model A in my basement running Apache2 and taking pictures
using the new Camera Module every few seconds of a wet area that I *hopefully* managed to patch. It is good fun, and I can also do timelapse video from the pictures. The Pi will even compile the timelapse for me!”

Drew Fustini will introduce us to programming the Beagle Bone Black in BoneScript.
I’ve been saying for years that Javascript would be the next hot language for microcontrollers – maybe it’s true. From beagleboard.org/Support/BoneScript

“BoneScript is a node.js-based language specifically optimized for the Beagle family and featuring familiar Arduino function calls, exported to the browser. Get started exploring the BoneScript Library to discover the great simplicity that is made possible by utilizing Linux in BoneScript.”

NERP Tonight! FPGA’s with Ste

NERP is not exclusively raspberry pi, the small computer interest group at Pumping Station:One in Chicago.

Ste Kulov (like “steve” without the “ve”) is the signal processing guru of Pumping Station:One. He’s also a great teacher who’s enthusiastic about sharing his knowledge of the theory and practice of analog and digital circuit design. Tonight Ste will show NERP what FPGA (Field Programmable Gate Array) chips do and how to use the chip manufacturers’ development tools.

Xilinx.com

Xilinx.com

FPGA’s are very fast logic chips that can perform better than microprocessor CPU’s in a number of high throughput applications. FPGA’s are programmable, but FPGA programs aren’t necessarily seqences of instruction like a C program would be. In fact, on an FPGA you can “write” a CPU. All the cool kids are learning to use FPGA’s, and you should, too!

Tonight’s agenda from Ste:
1.) What are FPGAs & CPLDs and what do they do?
2.) Why would you want to use one?
3.) Explain how you would program one using a hardware description
language such as VHDL or Verilog.
4.) Go over a quick Verilog example & demo of displaying “NERP” on the
4-digit 7-segment display on my dev board.
5.) With the remaining time, demo off my Nintendo DS video output
project to illustrate the neat stuff you can do with these things.

NERP tonight with Drew: Beagle Bone and Pi Face

beagle-hd-logo

NERP is not exclusively raspberry pi, the small computer interest group at
Pumping Station:One in Chicago.

Tonight Drew Fustini will demo the Beagle Bone.

BeagleBone (http://beagleboard.org/bone) is an open source, low-cost
credit-card-sized Linux computer that connects with the Internet and runs
software such as Android 4.0 and Ubuntu.

BeagleBone is capable of interfacing to all of your robotics motor
drivers, location or pressure sensors and 2D or 3D cameras. It can also run
OpenCV, OpenNI and other image collection and analysis software.

Through HDMI, VGA or LCD expansion boards, it is capable of decoding and
displaying mutliple video formats utilizing a completely open source software
stack and synchronizing playback over Ethernet or USB with other BeagleBoards.

Drew will also hit the high points of a Raspberry Pi interface board called the
Pi Face (http://pi.cs.man.ac.uk/interface.htm)

Pi-Face Digital is the first of a range of interfaces to allow the Raspberry Pi
to control and manipulate the real world. It allows the Raspberry Pi to read
switches connected to it – a door sensor or pressure pad perhaps, a microswitch
or reed switch, or a hand held button. With appropriate easy to write code, the
Raspberry Pi then drives outputs, powering motors, actuator, LEDs, light bulbs
or anything you can imagine to respond to the inputs.
