  1. Hi, and a great example of tight code. But ...... How is this pre-emptive? Why do I see this as round robin? What am I missing? Thanks and cheers.
  2. Many thanks. I'll PM you my details. At the moment, I have some connectivity issues with the forum PM service; so I'm replying to you via this forum. Cheers,
  3. @@Fmilburn It is very kind of you to offer your board to the community. Bravo. If there is a spare one, may I request it? I have both an AD9850 and a 6989 LP in my lab. If you are OK with this, I can give you some more details via PM.... Cheers.
  4. ------ sorry about this post (just above) ---- i just updated my page and saw the problem was solved ! congratulations!
  5. yes, i noticed this in the original post ..... Also, when I make int ledPin equal to either P1_0 or P1_6 the corresponding LED on the launchpad blinks as the code states. so, the conclusion is that at least some port pins are working. could the poster please confirm that GREEN and RED LEDs blink? if so, that's a good sign, but more work on testing those two ports is required. maybe using direct port mnemonics in energia: a---- Energia, all bits toggle on 2 ports of the 2553. then LED or voltmeter test each pin. ==== setup: { P2SEL |= 0xC0;
  6. Hi forum, I have many 5 volt LCDs. Here's an idea for using them on 3.3 volt MSP430 systems, other 3 volt systems and LaunchPads. Let's think of the typical 16 char x 2 row LCD, with a 16 pin connector (pin 1 = GND, pin 2 = Vcc, pin 3 = Vee, etc) and operate the MSP and LCD off only one 3volt source. No extra power supplies. I've been using this technique for a long while, its nothing new, you may have already seen it. PROBLEM STATEMENT - how to use a 5volt LCD unit on a 3.3 volt system without creating a separate 5v supply. SOLUTION SUMMARY - use a simple circuit to
  7. @@energia. Thanks for your reply. 1.... Download size. Thanks for confirming ti.rtos as the base for 432 e17 sketches, with the task loaded afterwards. I sort of figured this out, and have visited Rei Vilo's pages. . . I'm more used to traditional rtos environments (create, semophore, wait, etc, etc), so I've not yet thrown myself at the 432mt. But would have to understand how to do that 'multi-tab' in CCS, as that's my only way to load a LP with E17 code for now. 2....

  8. @@sven222 Hi again, In fact, I did notice that the ports were initialized in your code. In the spirit of helping you avoid some strange stuff I found out myself, here is a better explanation... The main point is that, AFTER RESET - P2SEL initial value is indeed 0xC0. See the 0x00 Family guide slau144, page 333, chapter 8.3, table 8.2. These must be changed to '00' for normal port IO. The default is so that the 2553 comes up working OK if a 32KHz xtal is installed. This means that even if you write to P2DIR and P2OUT, they will not do anything to P2.6 and
  9. @@sven222 Just coming back to your original request on 'lowest power possible'. You may want to be aware of setting Port 2 bits 6 and 7 to bit IO mode. After reset, they are set for supporting the 32KHz xtal. You can refer to the MSP430x2xx family guide, and the 2553 datasheet (Port IO page 53 ++) for the details. So, in your start up, execute this code: P2SEL = BIT7 + BIT6; // put bits 6 and 7 in IO mode. 2553 pins 18 and 19. This assumes: - you're using a 2553, probably on a LaunchPad (I ssume this as you mention only P1 and P2) -
  10. Hello @@energia Thanks for your patience; I had to get up to speed on : -- CCS cloud -- Energia projects in desktop CCS -- a few other things I've tried several things and here are the results, as far as I can see. PROBLEM RECAP Up till 25 Jan 2016 ======================================= I am not able to load E17 sketches into the 432LP. I get a 'DSLite.exe error message' when I attempt a load to LP. On the other hand, I can get full load / debug control of my 432LP from the CCSv6.1.1 desktop with straight C programs. GOOD NEWS ! SUMMARY

    @@Fmilburn..... A very interesting writeup, thanks. What a coincidence; I am working with the AD9850 DDS module this week ! Although your writeup is on FFTs done on ARM MSPs in the KHz range, here are some data and thoughts on the AD9850 DDS I captured which you, or others, may find useful. Note that the DDS frequency range here is 7.0 MHz. For instance, DDS spurs are not big at KHz, but being aware of them (as I'm sure you are!) is handy -- see 1 C below. This info may be useful to folks embedding DDS into radio / signal processing devices and is part of an investigati
  13. Hi, and welcome, There's a company called Elpotronic with a lite / free version of their up / down loader. Since you've used Energia, you are likely using a Launchpad, so Elpotronic should work. BUT - I've never used hexfiles before, so, Im afraid I won't be able to help you in those details. https://www.elprotronic.com/productdata;jsessionid=8C6E08AE222C9B84C30930264439B3E8 FET-Pro-430 Software Pkg. - LITE Installation package for FET-Pro-430, includes GUI, and supporting material.

I guess the white test at the bottom of the Energia window is what you were looking for from 'verbose mode'. (does it make sense that the bottom right corner of the E17 window says the 432LP is connected on Com2 ? the UARTs in my PC enumerated to 37 and 38. Just a thought)
  15. @@energia I'm please to help! For the first step, I ran DSLite from the DOS prompt and got the same error message immediately I hope I did the right thing. Then I took a screen shot of the following (left to right): - DOS window - error message - partial view of the folder within E17 - the DSLite.exe file properties (date / size / etc). I hope the screen shot comes through in this message on this forum, if not, I'll ttry again. NEXT STEP - I'll do what you requested on 'verbose' mode, running 'blink' uploade from E17 to the 432LP. cheers,
  16. Many thanks, @@energia. I do get that DSLite error message box prior to the upload errors that other folks have reported here in 43oh (previous threads on 'E17 Upload probs'). All the best, and hoping a workaround is forthcoming.

  20. As an idea, you could check the errata PDF for the MSP432, it accompanies the data sheet. Specifically, there's a few silicon bugs related to the REF module; this drives the ADC at 1.2, 1.45, 2.5, Vcc and Vss. I had some issues related to Vref selection and external output to pin P5.6 which were finally resolved by sequencing the ADC register bits appropriately to work around the bugs. This I did in CCS6, not Energia. Although I didn't experience your situation, perhaps this can help you.
  21. Thanks for this idea. I will check about User Account Control. Cheers,
  22. Hi Forum, I just started with MSP 432 on both Energia 17 and CCS6, and I'm having some issues. I've worked them as far as I can, and they seem to break down as below. I've used Energia for some years - a great tool. I use CCS a lot. I've been able to sort out 99% of MSP430 / Stellaris issues by myself, but now, I'm reaching out for some help to some wiser folks than I. I've checked this forum and TI e2e.

  23. Although you haven't given lots of detail, one thing you might investigate is direct DMA transfer from the ADC to UART. MSP430 DMA includes peripheral to peripheral, as the peripherals have memory addresses. Just an idea which I have not personally tried.
