MSP430 in 64-bit Ubuntu 12.04 Linux – the Arduino Way

Programming MSP430 microcontrollers in 64-bit Ubuntu 12.04 Linux

Programming MSP430 microcontrollers in 64-bit Ubuntu 12.04 Linux

I recently had a chance to take a closer look at programming a new (to me) familty of microcontrollers – MSP430 by Texas Instruments. The opportunity came courtesy of Newark, which is where the TI MSP430 Launchpad Development Board can be purchased on their Analog & Embedded Catalog website. I’ve had access to TI MSP430 development boards before but, since I ran a Linux shop here, the hurdles of using the stock Windows-based developing environment were too much for me and I never actually got to play with them and I’ve pretty much given up on TI until this opportunity came along. Much has changed since then, so keep reading if you are interested in working with MSP430 in Linux Read the rest of this entry »

Serial OLED display and Arduino – a perfect combination

Demo application for Seetron GLO-416Y serial OLED display

Every once in awhile your MCU, such as Arduino, needs to output some text and this is where you normally start bumping up against its limitations. Unless the MCU is exclusively serving a conventional LCD or other type of display capable of showing text, the display is pretty seriously taxing MCU’s available instructions cycles, memory as well as the number of output ports left after producing the useful work the device was designed for in the first place – move servos, scan inputs etc.

Enter the serial LCD Alternative – Seetron 4-line, 16-character Serial OLED Display which I recently had an opportunity to work with, thanks to Scott of Scott Edwards Electronics Inc., the manufacturer of this great device.
I will be using the display in a couple of projects I’m working on but I could not resist to check it out as soon as possible and that’s how the demo application you see below came about Read the rest of this entry »

FujiFilm FinePix F300EXR – don’t delay that upgrade!

FujiFilm FinePix F300EXR - do NOT use before upgrading the firmware

FujiFilm FinePix F300EXR - do NOT use before upgrading the firmware


So, I ‘ve got myself a new point-and-shoot digital camera – FujiFilm FinePix F300EXR, pictured above. I’ve had a great experience with an older FujiFil camera – FinePix Z – and thought that you cannot go wrong with these guys, especially given the impressive set of F300EXR features – 15x optical zoom, 12M Pixels sensor, bunch of preset shooting mode and even a panoramic mode which I never had on a camera before. Well, not so fast … Read the rest of this entry »

Arduino Nano V3.0 – MCU Development Made Smaller

Arduino Nano V3.0 board and a dime coin - a size comparizon

Arduino Nano V3.0 board and a dime coin - a size comparizon


I recently had an opportunity to add a new tool to my MCU development toolbox – an Arduino Nano V3.0. Newark – an electronic components distributor – was kind enough to send this little board for review. Arduino Nano is but one of their range of Arduino boards and shields and its tiny size which does not sacrifice performance or capabilities made it especially attractive to me. I have several Arduino-based projects lined up that could use smaller size boards and, based on the results I got so far, the Nano will definitely be a part of one of them in the future.
