  1. I know, but I routed a pcb based on pin mapping available on energia.nu, so I couldn't change this ... But I remembered that in the past I met exactly the same problem and wrote a modification of SPI library and pins_energia.h and it still works. I don't think Energia team will accept it but at least I will publish it when I get the time
  2. Hi, Little question : is SPI1 available on F5529 ? It's mentionned on pinmapping http://energia.nu/Guide_MSP430F5529LaunchPad.html but when I try to use it, no signal is generated, and when I look in librairies and core, I don't find where it's configurated (setModule() is only for EUSCI peripheral). Regards
  3. I'm using hardware i2c, and buffer size are the same, but it does not explain why it take so much RAM. Even 100 bytes would be rather normal, but 400 ?! That doesn't sound normal for me and I checked everywhere I don't see where this RAM is used EDIT : I updated to 1.0.2 it's much better with around 200 bytes. I still can't explain this memory footprint with a buffer of 16 ( x 4 if I understand how the library works) so I a read the library, I would say that 100 bytes would be fare
  4. Hi, If I'm not wrong, F_CPU is defined in boards.txt
  5. Hi, Energia of course I'm using the last release : 1.0.1 Regards
  6. Hi, I just noticed an excessive consumption of ram by Wire on G2553 (I did not test on other µC) : 400 bytes !! I took a look at Wire.h but can't find where this memory is used. If anyone can confirm this and/or have an idea about this issue ? Regards
  7. Be carreful, I recently noticed some differences between TivaC pinout diagram and reality. I did not take the time to push this issue on Github but I will do it as soon as possible.

    In addition, I succesfully used this one : http://cactus.io/hookups/sensors/barometric/bme280/hookup-arduino-to-bme280-barometric-pressure-sensor I just made some modifications to get sensor working in low power mode.
  9. There is a dedicated channel on ADC with VCC/2. You have to select 2,5v analog ref and select internal channel : analogRead(128 + 11) (if I remember well) 128 + X force energia to select the specific hardware channel X on analog multiplexer without mapping.
  10. Hi, How do you know that the SIM900 send anything ? Apparently you are using the same port for SIM900 and debug so ...
  11. The "normal" process is to make a push on Energia's github, what I did not do (I was having hard times when this troubles came to me, and I'm not a good user of github at all, so I clearly didn't have the time to push this mods).
  12. Hi, Last year I add a lot of troubles with i2c in Energia. I solved them but I don't know if Energia team included my corrections :
  13. Sorry but you have to see something in your serial monitor as you use the function ShowSerialData(), so after each command you should see the module response in the serial monitor.
