  1. Hi I just downloaded energia from energia.nu and tried to start it. It complains about the bundled Java Runtime being corrupted... I also tried to change the folder name to ti\energia, but to no avail. I'd be grateful for any help. Screenshot attached.
  2. Hi I am measuring two strain gauges with the first two differential ADC input channels on a MSP430i2041. I would like to measure the temperature of my DUT on one channel. All the app notes I found (SBAA275, SBAA330A, others ) suggest using a current source and then a reference resistor over the positive and negative reference inputs of the ADC. As I use the internal reference of the MSP430 for measuring the strain gauges, I can't exactly go and force another voltage on the reference. As a "cheap" possibility, would it be possible to connect VCC--[10k]--[PT1000]--[10k]--GND
  3. If I remember previous discussion in this forum correctly, spaces are not allowed in Energia-related paths.
  4. Something is out: http://www.ti.com/product/msp432e401y http://www.ti.com/product/msp432e411y They don't have exactly the expected part numbers, though. Both have 1024 kB Flash and 256 kB RAM and 120 MHz clock. Launchpad: http://www.ti.com/tool/msp-exp432e401y Strangely the 432P4111 launchpad http://www.ti.com/tool/MSP-EXP432P4111 seems tp be active now, too but the MCU is not available?
  5. Hi @dubnet Thank you very much for your answer, I think this issue was for ccs. With ccs6 there was a slow TI GraphicsLib and they sped it up significantly for ccs v7 but I am not sure that one can just drop that into energia and be done with it. I did run the CCSv7 Demo on the MSP432 and it was FAST. (I am not ready for jumping over to the world of direct register manipulation tho... Energia is a good compromise for me in order to get ahead with my hobby projects...)
  6. Hi All First, I would like to thank @Rei Vilo for providing the Library for the Kentec (BOOSTXL-k350qvg) library with Energia. I copied the code out of https://www.youtube.com/watch?v=XyeUpk6P4kA (as I didn't find the powerpoint or pdf) and got it to work with an MSP430F5529 launchpad. (Energia 18, Windows as the Mac version doesn't work atm). Then I compiled the same code on a MSP432P401R launchpad and it runs a lot slower than on the F5529 (I assume this is a known issue, due to slow SPI speed ( https://github.com/energia/msp432-core/issues/27 ) but also doesn't look the same, the

  9. Hi, I updated to OS X High sierra, and installed a fresh copy of energia 18 from energia.nu and replaced the arduino-builder with the one from above post, but unfortunately, blink fails to compile (board chosen F5529) /Applications/Energia.app/Contents/Java/arduino-builder -dump-prefs -logger=machine -hardware "/Applications/Energia.app/Contents/Java/hardware" -hardware "/Users/baettig/Library/Energia15/packages" -tools "/Applications/Energia.app/Contents/Java/tools-builder" -tools "/Applications/Energia.app/Contents/Java/hardware/tools/msp430" -tools "/Users/baettig/Library/E
  10. Hi, is that also possible with SPI in case there are several SPI interfaces? (One interface at a time means one per sketch or the first interface, then the second, then the first again in the same sketch?) Thank you very much
  11. Well, I tried ordering two of the boards and a couple small tx modules. Luckily they sent me a mail asking if I accepted their shipping charge of 76.81 USD. (for a total of 31 USD of components) Which feels outrageous and so I politely declined... I chose "cheapest international shipping method", so for living out of the US it's simply out of any range of justification for a hobby purchase.
  12. @@greeeg , iirc they do stencils, too. But as you say, depending on use case and shipping specifics the one or the other may be cheaper. @@zeke, not sure if you got my PM?

  14. Hi @@zeke in my (limited) opinion, their work is good. Here's a board (the gerbers came from an eevblog member,[1] not mine) I had made privately: I had some made, the one I soldered the components on works perfectly. Of the ones from work I don't have any pictures obviously, they were only for a small project with a few components. The finish there was ENIG, which also turned out really well.
