  1. it would appear to be so. If you have the 5529 Launchpad it would easy to confirm.
  2. You would need to take a look at the documentation for the F5529 to verify that it can be awakened with a GPIO interrupt. In a very deep sleep, IIRC, the list of available interrupt sources gets shorter. So if LPM4.5 supports a GPIO transition as a wakeup source you should be good to go.
  3. Are you using the 432 Launchpad black PCB or the red PCB? If you are using the black there are issues with the now obsolete black board. By using an earlier version of Energia (e.g. V16 or V17), it may solve the issue.
  4. First of all, welcome to the forum. If I remember correctly, the software serial library isn't supported on the F5529, only on the lower end G2 parts without built in hardware serial. However, it shouldn't be needed as the 5529 has two hardware serial ports. The second serial port would be referred to as Serial1 (e.g. "Serial1.begin" as opposed to the first serial port "Serial.begin"). Refer to the pin outs on energia.nu for the correct pins for each port.
  5. @NurseBob Not familiar with that one, but they do have an infinite bag of tricks. A memorable experience was when I was young.... I stayed over at friend's house in Southern California and slept on a pull out couch sofa bed. They had a cat with a bell on it's collar. The room was fairly dark but I could hear the cat moving about the room, and then silence. The cat would then launch from his perch on the back of the couch and land on my head or body. I would shoo him off and the process would repeat, until I determined he was having far more fun than I was and wouldn't quit this game any time soon, At that point I prevailed upon my friend to put the cat on lockdown for the night.
  6. Welcome to the forum!
  7. @NurseBob Happy to hear that you are all ok. Given the hurricanes, earthquakes and wildfires it has been a tough year for lots of folk. Your cats may seem to have forgiven you but they are just waiting for the right opportunity.....
  8. @NurseBob Was saddened to see the destruction and loss of life due to the wildfires. Hopefully you won't be affected but please evacuate without a moments hesitation if it even starts to move toward you. In the big picture stuff is truly meaningless and life is precious.
  9. When I have utilized EnergyTrace in the past I have found that I had to disconnect all FET data lines in order to get a measurement that was close to the calculated current consumption. You could try disconnecting the TDIO and TCK lines, leaving just 3.3V and ground connected between your target and the FET to see if that improves the measurement.
  10. I vaguely remember something a while back on the E2E forums with regard to the Kentec driver/library not being right on the 432. If I recall correctly, there was an updated version referred to which sped up the display significantly and made the original poster happy. A well worded search should find that thread. EDIT: Did a few searches and couldn't find it. Perhaps it was not the 432 but a Tiva issue. That's the trouble with vague memories.... You may want to try posting on E2E if you can't find it by searching. If it is indeed the issue I seem to remember, then perhaps one of the TI guys might recall and be able to help out.
  11. No problem. Happy to hear you got it resolved.
  12. I think I might see what the problem is. Energia places the some things in the User folder which you have apparently named "Mike KM6KWG" which has a space in it. If you have another user account without spaces that you can use, or create a new user account without spaces, and then install while logged into that user name. You may also want to make that user account an administrator account to eliminate that variable. You can revert it to a standard user account if you want when you have a successful install.
  13. First of all, welcome to the forum. It appears that a space in your file path may be causing the issue. Best to avoid spaces, special characters and long path names with Energia. I typically put Energia in the root of C: and use a short path structure ( e.g. c:\energia ).
  14. If I am not mistaken, the F149 doesn't support Spy-Bi-Wire using RST and TST. It only supports full JTAG which uses TDI, TDO, TCK, TMS, etc. TI's MSP-FET430UIF should support full JTAG ( http://www.ti.com/tool/msp-fet430uif ).
  15. You may want to take a look at page 29 and 30 of the 2553 datasheet which characterizes the DCO. The DCO is not particularly accurate and my guess is that you will need the crystal to get the accuracy you are looking for as well as better consistency from device to device. EDIT: forgot the link to the datasheet http://www.ti.com/lit/ds/symlink/msp430g2553.pdf
  16. My understanding is that Energia will consume more resources than an equivalent program written in C using, for example, CCS. Since Energia abstracts away some of the hardware details in favor of simpler programming, that abstraction consumes extra flash and ram. Trying V12 of Energia as Rei Vilo suggested or moving to CCS would perhaps get the numbers down to what you are expecting/require for your application.
  17. Welcome to the forum!
  18. Welcome to the forum!
  19. By the way, if you are using the XMS version of the MSP432 then you are should have the black board. I believe that the sensitivity issue has been addressed in the final board release (red board). I know that TI has been pretty strongly recommending moving to the red board since the black board used the pre-production XMS silicon.
  20. Your circuit diagram didn't post. Given your symptoms the diagram will be very helpful in trying to understand the problem.
  21. If you read through some of the posts on E2E there may be a solution in terms of replacing the damaged part, but that may not be worth the cost or trouble. The other solution is to replace the board.
  22. This is a known issue typically due to static/handling damage. Please see the E2E site for more info: http://e2e.ti.com/search?q=msp432 gets hot
  23. The multi-tasking examples are for the MCUs that have the resources (processing power, memory, etc) to handle the TI-RTOS overhead. The value line series (like the 2553 you are using) are not capable of running the real time operating system. The MSP432 is a good example of a MCU that can run the multi-tasking environment.
  24. I have at times used the calculator that comes with windows to do quick hex -> binary as well as binary -> hex. From the view menu of the calculator, choose "Programmer". Once you have moved past the blinking LED and dive further into the wonderful world of microcontrollers, you will appreciate having a logic analyzer with 8-16 channels. They are worth their weight in gold when troubleshooting communication problems.
  25. First off, welcome to the forum. A couple of ideas come to mind. The first is that you might want to consider controlling the power to the SD card with a free I/O line and a transistor, only powering it up when you need to write to it. The other idea is to store multiple samples in an array (which should survive going into low power mode and back) and write them to the SD card every hour or more. How many samples to store between writes to the SD card would depend on your confidence that you wouldn't lose power or have a reset condition before having a chance to move them to the card.
