Hello Everyone, We owe this update to you, since you guys are the main drivers of this portal, submitting and discussing the MSP430 and everything else. We would also like to thank our sponsors - Texas Instruments for the TI Chronos watch and Geekdoc for the Launchpad 1. The 43oh blog received ~16000 pageviews this month and has steadily grown. We get around 400 pageviews a day, still small but a big jump from last month.(~9000) 2. The forum received ~26000 pageviews this month. The good part of the board is that we have a steadily growing Projects section with code and schem

EDIT: Here's another really nice DCO calibration program. It's part of TinyOS-msp430. http://code.google.com/p/tinyos-msp430/ It's the file called calibrate-dco. As gordon, who discovered it said, "[it] appears to be a quite beefed-up DCO calibration app, with goodies on the side (taking silicon errata into account for various devices when calibrating)." It looks like it's built to be solid and reliable. I skimmed over the code and didn't see anything for calculating SegA checksum, but that usually isn't an issue for most non-critical applications. EDIT: maxpenna shared another versi

Did you guys see this: http://focus.ti.com/general/docs/video/ ... grace_em_v * GUI-based configuration tool for setting up ADCs, OpAmps, Timers, Clocks, GPIO, Comparators, Serial Communication, and other MSP430 peripherals. * Generates easy-to-understand C code that properly configures your device * Supports all MSP430 Value Line devices (MSP430G2xx) and select F2xx devices * Compatible with LaunchPad and most eZ430 tools * Grace tooltips offer helpful popups and hints for properly configuring your MSP430 device * Grace provides a Basic, Power User, and Regis

I found it: When you are creating a new project, after the project settings - You will find it in Project Templates. Kind of hidden within layers.

I submitted this to HaD too. It's not as flashy as the TV out I just submitted, but I know HaD readers who use Launchpad would find it useful. It will also be good press for 43oh, right?

2n3904 would be right at the limit at 200ma, we should get the 2n4401 (rated at 600ma) or 2n2222 (at 500ma), usually u would want to stay at 50% of the rated limit to be on the safe side. // MSP430F20xx // --------------- +9V // /|\| XIN| | // | | | | // --|RST XOUT| o // | | connect to strobe // | | o // | | | // | | |/ // |
