Poor Mans Scratch Sensor Board
“scratch-sherpa” implements the protocol of the Scratch Sensor Board (also known as Picoboard), as supported by the educational Scratch programming environment. A MSP430 Launchpad with my uSherpa firmware as foundation is used. For more details, see the project page here Get the sources from github The (unedited) video below shows some examples of how the [...]
Carambola SoC Stand Alone with MSP430 Piggyback
Like I wrote in this article, it is pretty easy to run the Carambola SoC stand alone. Today I finished the Carambola-MSP430 (for MSP430 stand-alone see this article) Piggyback I intend to use as a replacement for the current jumper wired brains of my Carambot. The Carambola comes with 2mm pin connectors, I used a [...]
ROCKETuC Introduction
I just made two short videos introducing the main features of the ROCKETuC project I work on with Alexander Reben. The first one gives a basic introduction to ROCKETuC and what you can do with it, the second one shows how external interrupts could be used with ROCKETuC and Processing. Basically I made them to [...]
Ultra Sonic Range Finder on Pan-Tilt
Range finder on server pan tilt looking funny . The servos are driven by a Launchpad with MSP430G2553, as well is the ultra sonic range finder. The range finder is a SFR05. I am planning to implant that PTRF (pan-tilt-range-finder) into carambot to make it drive autonomous.
Multiple Time Bases on a Single MSP430 Timer Module
On dangerousprototypes.com, they refer to an other interesting TI app-note which describes how to use multiple time bases on a single MSP430 module: However, in some applications, multiple time bases are needed to generate multiple output frequencies. Normally this is done using multiple timer modules, but this might require upgrading to a part with many [...]
Interfacing the 3-V MSP430 to 5-V Circuits
On Dangerous Prototypes, they point to an app-note from TI which shows various ways of level-shifting between a 3V MCU (like the MSP430) and 5V peripherals. The paper includes various examples for input, output and bi-directional level-shifting. They also cover the topic power-supply, giving examples on how to provide both: 3V and 5V to your [...]
Robot with MSP430 Launchpad as Brains
Longhorn engineer has has a nice and clean robot build with an MSP430 Lauchpad as Brains on his web-page. I like especially the design of the power supply: It has 3 switching power supplies providing 3V at 4A, 3.3V at 500mA, and 5V at 1A. The main power source is a single cell 3.7V lithium [...]
Launchprog – Use the MSP430 Launchpad as AVR Programmer
There is an article on Mikrocontroller.net (english translation)which describes how to use the TI Launchpad as an AVR programmer (the included MSP430G221 is goog enough for that!). The firmware they offer for download allows one to program an AVR chip through the avrdude tool. Nice job I’d say.
“Bad” Expansion Header Pins on the Beaglebone
While making my first “cap” for the Beaglebone (working on a YWasp cap), I learned the hard way that not all pins on the expansion header of the bone are “good” pins. After putting the cap (which I worked stand alone fine) on the bone, it refused to boot! When taking the MSP430G2553 out of [...]
The Glowing eBunny – Happy Easter
This is just a quick little Easter hack. My wife brought in two cute little glass Easter bunnies lately, and they really demanded for a mod. Well then. The bunnies got a blue LED implanted each, the LEDs where connected to a MSP430G2231 MCU, and the MCU is driven by a small firmware which pulses [...]
