Hi, I've searched the messages but not had any luck finding out how much memory is needed to support the SD card file system. I think I've got a reasonable understanding of the two styles of interface at the physical layer. But often we need some logic to deal with the file system, such as it is. Suggested sources?

Hi. I have a friend who is looking for a small demo board for the CC430F6147. He's looking for a minimal system, just the basic parts to get it to run, with a PCB antenna and a few points to connect to a SPI peripheral. He's doing a feasibility trial for a product and is hoping to avoid the fussy RF layout required, and the expensive assembly of the 0201 sized passives. The demo board from TI i...

TI claims they have fixed the RTC in the "A" version, so I was trying to implement the RTC Workaround described in slac166r document. It contains the files: "RTC.h",...

Hey everybody, About two weeks ago I started making a serious effort to learn to use the MSP430 Launchpad (with MSP430F2012). I have no prior experience coding in C or C++, so I wanted to describe what I've learned, and get some feedback, just to make sure I understand everything correctly. In the "blink your first LED" tutorial there is the following piece of code: P1DIR |= 0x01; It explai...
