  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.

  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.

  16. Hi Zeke, I was using http://www.pcbway.com/ at work and for a private project or two. At work we paid for fast shipping on some small simple boards that we needed quickly, the boards got here in less than a work week and looked good (and performed well). Otherwise you can check on http://www.pcbshopper.com/, they run comparisons on your size and time-requirements to help you find the optimal boardhouse. (I am unaffiliated with either company, only a customer and I used pcbshoppers website).
  17. Thank you very much for the info. I am in Switzerland, so I probably better forget about it... Unfortunately this board is not available with mouser, farnell, which ship to Switzerland for free if the order is for more than a certain amount.
  18. Hi @@artium Thank you very much for making this library available. I compiled it on a F5529 launchpad without issue (needed to adapt the pins slightly) I am trying to get it working on the msp432 now, however I am running into problems. First it mentions that min(,) is not defined, this is easily circumvented with two definesat the top of the sketch: https://github.com/energia/Energia/issues/815 Then I changed volatile RwReg with volatile int32_t in the h file where the SPI pin pointers are defined. Unfortunately, now the compiler tells me that digitalpintoport and associated fu
  19. Did anyone order these boards by chance and could report on international shipping costs? I went through the whole order process and would have had to click confirm order without knowing the shipping costs... There are not estimates anywhere to be found unfortunately. (The boards are now up to 10 USD a piece...) Thank you very much

  21. Hi @Kelton Two quick questions: Did you restart energies after adding the libraries? It needs to read in the directories. Did you format your drive with the case sensitive hfs+ ? Then you'd need to match the spellings.
  22. Thank you very much. I am not yet sure if I really want to invest in a cnc mill or if a reflow oven (T962 or T-962A, where I am not sure what the differences are other than the price...) But it is interesting to see what is out there. Your project is really great, btw, kudos also from me!
  23. @@greeeg thank you for posting the guide! What kind of mill are you using? Sent from my SM-N9005 using Tapatalk
  24. Hi @@greeeg I downloaded cadstar and it installed design editor, library editor and migrate tool. If I transfer an example schematic to pcb I get a message that "the pcb design editor will work in unlicensed mode" and ... saving might not need possible. If I understand correctly, that would be included in cadstar express (or bigger) "The latest version of the CADSTAR Express free evaluation software for simple designs (limited to 50 components and 300 pins, is available to download at www.zuken.com/cadstar-express."

  25. Hi Zeke, thank you very much for posting these offers. As I am only acquainted with Eagle I wanted to ask whether the featured Cadstar (or Orcad) packages are "just" schematic capture packages or whether one can prepare, route PCBs and export the Gerbers for production? Thank you very much!
