  1. Hi All, I cleaned up the site last week. This year has not been the greatest for me(and for alot). Pardon the neglect. True that the blog has not been update, but I have not seen much content on the MSP430/432. Also TI's E2E has been vastly popular. There was no "commercial" side. I still pay for server and forum licenses out of pocket. I've kept it up since there is alot of useful info and people benefit from it.

  2. And with J7 removed, everything works just fine. Note to the future: if trying to do I2C on EXP430G2ET, remove J7. It probably says that somewhere in the user guide.

  3. I locked myself out by incorrectly programming GPIO reg C. I used the LMflashprogrammer to unlock it.

  4. As far as I can remember, the G2553 has a very small serial buffer. Just try to reduce the number of byte to send, e.g. AT: Instead of Enter AT commands:

  5. G2553 has a Hardware Serial Interface, so do not use the Software implementation. Serial BTSerial..... Should work

  6. Which MSP430 are you using? I recently tested it on an MSP430F5529 and that worked. One thing to note though is that pins 3 and 4 are already used by Hardware Serial which you use in your Sketch (Serial.xyz()). Try changing to different pins. I would suggest you try pins 11 and 12 if you are not using those for anything else. Robert

  7. Yes, of course you can do that. Just for the Launchpad the numbering is always done on the boarder of the PCB = Pin Headers of the board, as this is the point where a typical user would connect something. If you prefer for your own board to have the device pin numbers used - you can do that. Doing the updates as you mentioned above should do that 🙂 To get the board in the GUI you need to - add a device in the variants folder - as just discussed with the update of the pins_energia.h file - add a section into the boards.txt file (located in the folder above) in a s

  8. I'v solved this issue installing previous version of Energia. It's works. Release version 1.8.7E21 (10/17/2018) upload correctly.

    MSP430 Nixie Clock

    I have a zip file of @RobG's Nixie Clock V3. @RobG, I hope you are okay with me posting this? @bluehash, please delete this if there is a problem.

  10. Thanks, for the feedback. I have already implemented the fixes based on your findings and planning for an update release of this package.

    @Abdul400 There is no need to post the same question multiple times, as already at Please refer to: Netiquette for Newbies Porting an Arduino library to Energia

  12. It looks like that the compiler setting for the large memory model is not set correct. can you open the platform.txt file in c:/users/johnw/appdata/local/energia15/packages/energia/hardware/msp430elf/2.0.7/platform.txt and change line 21 from compiler.mlarge_flag=-mlarge -mcode-region=upper to compiler.mlarge_flag=-mlarge -mcode-region=either

  13. You could use a library designed for Arduino. See Porting an Arduino library to Energia

  14. >energia also has in its software serial library error Well, no. The 5529 has hardware serial. Don't use software serial. FWIW, it's not an error in Energia, but a limitation of the software serial library that it can't run with the faster clock. HTH

  15. Sorry being a newbie to 430oh.com if this is a no-no posting to old threads. But did get the Neopixel Library working with an MSP432 Launchpad (some tweaking of the Cortex-Mx assembly required. Much thanks to the WS2811 driver mentioned here: Only problem is I am not the greatest C++ programmer and had to hardcode the GPIO somewhat in Adafruit_NeoPixel.cpp : //jg 12/5/17 P1.0 is pin 78. 0x40004C02 YELLOW_LED //jg 12/5/17 P2.0 is pin 75. 0x40004C03 RED_LED //jg 1/3/18 P3.0 is pin 18. 0x40004C03 - Gets Neopixel off LED jumper on MSP432 LP But hooks are in Adafruit_NeoPi

  16. EMT low power unfortunately is not well documented but quite simple. How low of a power the device goes into depends on what interfaces are open and what device the Sketch runs on. The quick reference: If all Sketches are in delay() the idle loop is entered. The idle loop is a TI-RTOS task that consults the power manager and then determines what level of low power it can go to. Make sure that all unused pins are in the appropriate state according to the datasheet. Usually this is output high. Make sure that sensors that are connected are put into sleep mode if you intend to go to low p

    Volt/Amp/Watt meter

    This is a simple voltage and current meter that uses the TI INA219 chip. Voltage measurement range is 0 to 26 volts with 4 mV resolution and current measurement range is -4 to +4 amps with 1 mV resolution (when using a 0.01 ohm shunt). The specs are inferior to a pair of quality multimeters, but it is a fraction of the price and shows wattage in addition to voltage and current. The Nokia 5110 display is used so the firmware could be enhanced to do simple graphing. Sending the measurements to a computer could also be done. Using the INA219 makes for a very simple circuit.
