  1. Try with Energia release 17.
  2. Also of interest, 5 tips for getting quick help on E2E. https://e2e.ti.com/group/helpcentral/b/weblog/archive/2015/07/17/5-tips-for-getting-quick-help-on-e2e
  3. Give the DHT12 a try: it supports standard I²C.
  4. Unfortunately, I don't have answers to all your questions. If you're working in academia, you may contact https://university.ti.com/en directly. LaunchPad CC1310 is sub-1 GHz, not WiFi. Contrary to what the BoosterPack Checker says, LaunchPad CC3200 is not compatible with the Education BoosterPack MKII, because analog inputs are limited to 1,5V on the LaunchPad CC3200. Please refer to this review for more details.
  5. Have you checked the usual suspects at I²C Check-List https://forum.43oh.com/topic/13067-suggestion-add-a-faq
  6. It looks like the I²C implementation requires a specific period between write and read.
  7. See Porting an Arduino library to Energia at Now, it seems that the library is not ready, as per In this very case, the easiest way would be to develop your own Firebase library from scratch based on its specifications.
  8. @Germ You're welcome, enjoy Energia!

  12. You need to add a specific board for the r-iot and define it. See Add a New Board to Energia at
  13. I managed to get my BME280 working. The error was a wrong address. The library was set to 0x77 by default while my sensor had 0x76 configured. See https://github.com/adafruit/Adafruit_BME280_Library/issues/15 Now, Emulated I²C on pins 9 + 10 works with Energia 17. Hardware I²C on pins 14 + 15 does not work with Energia 17. Hardware I²C on pins 14 + 15 works with Energia 12. As an additional benefit for Energia 12, the code is more compact! I opened a ticket at https://github.com/energia/msp430-lg-core/issues/62.
  14. The I²C port on pins 9 and 10 (module 1) is simulated and may not support advanced features like clock stretching. I recommend you to use pins 14 and 15 (module 0) with the hardware I²C. Have you tried with another board? I tried with a BME280 I have at hand, but I can't manage to read the data whatever the board.
  15. Yes, you can stack multiple BoosterPacks. See this project: However, you need to check the compatibility of the BoosterPacks and the LaunchPad. Just use the online tool BoosterPack Checker at https://dev.ti.com/bpchecker/
  16. The I²C implementation on pins 9 and 10 is software-based (or bit-banging). Some functions may work differently from the hardware ones. Let me try with a very standard I²C device.
  17. The MSP430G2553 has two I²C ports available. See I²C Check-List at
  18. Feel free to contribute to the Energia project!
  19. You can have a look at https://embeddedcomputing.weebly.com/standalone-msp430g2955.html
  20. For the MSP430G2955, please have a look at https://github.com/energia/msp430-lg-core/tree/G2955_support.
  21. Also, the MSP430G2 LaunchPad seems to have the serial UART limited to 9600 bauds. I strongly recommend to go for a more modern LaunchPad, like those @Fmilburn suggests.
  22. Please refer to the pins maps. https://embeddedcomputing.weebly.com/msp430-launchpad-with-msp430g2553-pins-maps.html http://energia.nu/pin-maps/guide_msp430g2launchpad/
