LED POV magic with MSP430

Cropped thumbnail

This simple project exploits the Persistence Of Vision (POV) of 8 LEDS connected to a port on the MSP430G2211 MCU, this is the chip I had available but the project should also work on other 14-pin devices of the same family. I’ve built this boards as a New Year’s present for my nephews. Schematics The […]

This short tutorial is about getting started with the development of OpenChronos NG firmware for the eZ430Chronos watch under Ubuntu Linux LTS. This nice development tool in a watch was also described in my previous article:  http://www.itopen.it/2013/11/28/the-hackable-watch-a-wearable-msp430-mcu/. Preparing the development environment Starting the development with OpenCronos NG wasn’t the easiest thing I’ve done recently: most difficult […]

It’s quite some time now that I started programming with low-cost MSP430 MCUs development kits, I must admit that sometimes I need more RAM and flash but I like this MCU a lot: its advanced clock configuration options, the 16bit Von-Neumann architecture and the low power modes make this MCU an ideal option for battery […]

New Energia LedControl library

Cropped thumbnail

Today I was really tired of my everyday web dev job and started playing with a spare MSP430G2553, an 8×8 led matrix  and an AS1106 (a 2.7 V MAX7219 clone). After a few tries, I decided to port the great LedControl library to LaunchPad Energia. I had to move the chip initialization from the class […]

Driving a pair of 7 segments display with MSP430 Energia libraries

Cropped thumbnail

This is my second experiment with Energia LaunchPad boards. This time I wanted to see how difficult could be to adapt for the LaunchPad a program which I originally developed for Arduino. If are interested in how I did setup my Linux box for working with the LaunchPad and the Energia libraries, I’ve described the whole […]

MSP430 LaunchPad Energia development on Linux

Cropped thumbnail

A new baby is sitting on my desktop: yesterday arrived the MSP430 powered Launchpad development board.  These few notes describe the steps I did to setup a development environment for this board on Ubuntu Linux 12.04 LTS 64bit. The launchpad board Update: at the beginning of March 2012 TI raised the price of LaunchPad board […]
