TI has a new application note on implementing sensor fusion using the Direct Cosine Matrix algorithm. This example uses a magnetometer, accelerometer, gyroscope and a pressure sensor to get a complete measurement of orientation, relative to the earth’s magnetic field. The algorithm currently uses 30% of the MSPs CPU time. This application report...

Turd shares his example code for talking to a 256kb EEPROM 24LC256 I2c chip. The interface uses the USCI module of the G2553. It first writes “HELLO WORLD” to 0×0000 then reads it back and sends it out the UART at...

Geekdoc, from the Forums, let us know about Larcie’s online MSP430 editor. This allows you to write code, compile it and download the binary from the editor server. In short, You edit C-code within your web browser without having to install an IDE such as IAR or CCS on your computer. The files are compiled on our server and you download them from there....

A few weeks back we were able to talk to an SDcard using the famous PetiteFaTFS as the file system on an MSP430G2553 using the USCI module. The code as it is right now supports format, open and read. Write support will not be too hard. Commands have to be created for the parser. The above image shows the SDCard on the new 43oh SDCard Booster pack. The good...

Mtlevine0 used his Launchpad to connect serially to a Twitter handle via a Python script. A LED display is connected to the Launchpad to display the updates. This would be very handy to control and actuate devices over the web via Twitter. His python script and msp430 code is shared in this forum thread. A Python script running on my PC fetches the most recent...
