    After joining this forum over 3 years ago I thought it overdue that I say hello and contribute something that I hope you will find useful. Attached is a picture of simple booster packs that I make. But are they really a "booster pack"? Hmmm. Debatable! They are cheap and easy to make and I have made 5 of them. I use them all the time because the whole of each project, including the MSP430, is attached to the booster pack. This means I can switch between projects without re-wiring, I can change the model of MSP430 in seconds and I only need one Launchpad. You can see from the picture that I provide two sets of header pins to attach "stuff" to, but provide four header pins for the 3.3V and GND. I also use long-leaded header plugs, partly because I have to solder the strip boards "upside down" (notice the small gap between the strip board and the header sockets) and also because the excess leads are easily accessible test points for things like logic analysers, etc. I keep the strip board to the smallest possible size so that all the Launchpad jumpers remain accessible. I've tried different designs, some with LEDs, switches, small breadboards and more besides, but this is the one I use all the time. I call it a "pop top" because you pop the top off a launchpad and swap it for another, then another. That's all for now. Hopefully it'll not be another 3 years before my next posting!

    Although all the LaunchPads feature a programmer-debugger, sometimes an external one might be useful. Segger has just launched the J-Link EDU Mini, with all the software and expertise of Segger, priced at just USD18! I'm very happy with the larger Segger J-Link Edu priced at USD60. I've ordered one J-Link EDU Mini and plan to review it.

    Well, I think adapter is more appropriate, but let's call it a booster pack. There is nothing fancy, few connection options and a reset RC.

    Hi, I'm working in this library with some useful DSP and math functions (ideally focusing on embedded systems). Currently it's in the initial version with few functions, but I hope to add more in the next update. I prefered to use some structs to save parameters and use just one function to various instances of filters (very versatile). Functions - High Pass Filter (Single pole): Float, fixed and fixed extended version (with more bits to fractional part) - Low Pass Filter (Single Pole): Float, fixed, fixed extended and fixed fast (with some limitations related to cuttof frequency, but more efficienty. - RMS value: calculate RMS value of an array or sample by sample. Currently using square root function of math.h, but in the next update I will add a optimized version. I hope this can be useful. Feel free to test, share and contribute with this project.

    Hi everyone, I updated the library adding some functions: - to easily generate sine waves in a array and iteratively - goertzel dft using array data or sample by sample (very interesting because not need an array) Enjoy it Github: https://github.com/agaelema/DSP_and_Math

    Has anyone seen the : Mini-M4 for Tiva-C https://download.mikroe.com/documents/starter-boards/mini/tiva/mini-m4-tiva-manual-v100.pdf Would it be safe to assume that it could run energia? Best, C.

    Hi, I noted this device in july when I updated CCS and do some search in the "Research explorer". Very interesting. There is some examples in the "SimpleLink MSP432 SDK" and one image of the probable launchpad (very interesting).

    Have you visited http://energia.nu? A pins map is provided for each supported LaunchPad. Have you performed a search about I²C on this very forum? It contains the answer to your question —hint: pull-ups. Why are you posting the same question twice? One suffices.

    Hi, If I'm not wrong, F_CPU is defined in boards.txt

    His implementation is very simple but not so flexible. You can find a more complete c++ template implementation here: https://github.com/RickKimball/fabooh/blob/master/examples/serial/ascii_table_iostream/ascii_table_iostream.cpp - ascii table dump using operator insertion or standard function calls https://github.com/RickKimball/fabooh/tree/master/examples/math .. sine table prints using cordic, fixed math and floats fabooh support eusci, usci, software only (on any pin) with multiple instances and finally timer based serial.
