    MSP430G2553 Launchpad GPIO pins broken?

    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; // P2_6 and 7 to IO mode P2DIR = 0xFF; P2OUT = 0xFF; // P1DIR = 0xFF; P1OUT = 0xFF; } loop: { P1OUT = 0; P2OUT = 0; delay(1000); // longish delay to see the change on a DVM P1OUT = 0xFF; P2OUT = 0xFF; delay(1000); } b--- CCS ==== but the best would be CCS: write the same short loops, then in 'debugger', without even starting the program, just manipulate each PORT bit to 0 or 1 from 'register view', then check each pin with a voltmeter or LED probe.
  5. 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 create a negative voltage from the MSP 430 ACLK. This negative voltage then drives the LCD Vee on pin 3. The ACLK ***must*** be enabled in your software. You can enable ACLK in either CCS or Energia. Current measurements and waveforms are shown below. Clearly, you have to sacrifice use of the PORT P1_0 (red LED) pin, but this can be a reasonable trade off. If you can't do this, then you can use another MSP output to generate the negative voltage. HARDWARE - a-- create a simple negative voltage charge pump (two capacitors, 2 diodes). - input is from MSP ACLK pin +- 12 KHz. - output is to LCD Vee, which is almost always pin 3. b-- here is a simple charge pump circuit: (please do google this if you've a question, it is really simple) | | || ACLK -->---| |---------O----------||<|------O--------->---- to Vee, pin3 on LCD. | | | || | C1 | D2 | | | === ===== D1 \ / C2 ===== ======= | | | | | | | GROUND GROUND Typical component values are not critical. I used: C1 = C2 = 1 uF. D1 = D2 = Germanium 1N569. Results are below. c-- then connect the LCD module as follows: - pin1 to GROUND - pin2 to +3.3 volts (same line as the MSP430 positive supply) - pin3 to the charge pump inverter circuit, above in para 'b'. - all the other pins (RS R/W E DATA0-7) to PORT pins suitable for your application. d-- the scope output of the waveform in actual operation is shown in the scope screen shot below. SOFTWARE - you must enable the ACLK / VLO to be output from the MSP430: P2SEL |= 0x07; // aclk P2_0 pin8. smclk P2_1 pin9. ta0 3 P2DIR |= 0x07; BCSCTL3 = LFXT1S_2; // aclk = vloclk abt 12khz This can be done in CCS or in Energia 'SETUP'. CURRENT CONSUMPTION - .... With this configuration: - MSP430F2272 at 1MHz, PORTs 1,3,4 all set to OUTPUT LOW. PORT 2 set up as above. 4 x 20 LCD with blue backlight (powered by 3.3volts to a reasonable back light output) .... here is the typical current consumption I measured: - MSP430F2272 running tight loop, 1MHz 1.1 mA - loop + charge pump 1.55 mA <<<< so, only 0.45 mA for the charge pump - loop + charge pump + LCD backlight 9.44 mA (these are high efficiency blue LEDs) PLUS POINTS - - only one power supply needed for a simple 430 + LCD project. - rather low current consumption - even lower current consumption by switching ACLK off (but then you should turn off the LCD Vcc +3.3 - use another PORT pin as the LCD Vcc) MINUS POINTS - - you have to use a MSP430 port pin ALTERNATIVES - - use a timer / int driven PORT pin to replace the ACLK. - LCD too much contrast? : - insert series resistor to LCD Vee from charge pump to reduce neg volts - LCD not enough contrast? : - use a negative voltage triple / quadrupler. Hope someone can use this idea..... Cheers.

  7. 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. Please help -- How to get my MSP432 LP application UARTs to appear correctly. -- How to get MSP432 Energia sketches to compile correctly. Thanks folks !!!! Here's the situation..... 1. Application UARTs on 432 The first problem is that Windows device manager reports 2 (two) XDS110 devices in error. I cannot resolve this error by using the latest drivers /DSPinst.exe / DSLite / etc. As a result, there are no application UARTs available. But, CCSv6 allows me to upload compiled code, and to debug the MSP432 LP. ATTACHMENT : screenshot of 'MSP432 - applic uart drivers in error'. The message, not in English, says the file, folder, or volume name is incorrect. I've got Energia in C:\ 2. Compiling sketches for the MSP432 Now, turning to Energia v 17, here's what happens. (BTW, same on E v 16). a) if I VERIFY the basic 'Blink' sketch, I get a massive number of errors. Attachment: screenshot of 'MSP432 e17 blink w errors' If I try to UPLOAD the basic 'Blink' sketch, the same errors of course, but with a DSLite error message. Attachment: screenshot of 'MSP432 e17 blink w errors and DSLite error' c) just for the record, I sucessfully compiled a MSP430G2553 Blink sketch Attachment: screenshot of 'MSP430g2553 e17 blink w NO errors' d) and lastly, I'm able to complie / download / debug the MSP432 LP via CCSv6 (but no application UARTs) Some things I've done: - removed / reinstalled Energias 16 / 17. Now using 17. - undated CCSv6 to the latest - ensured Java is up to date - run various versions of the drivers for the MSP432 LP XDS110 driver installs. Then always getting the same errors / no UARTs as reported by Device Manager. CONFIG NOTES: 1. my overall system setup: MSP432 LP rev1.0. MSP430 LPs: G2553 / F5529 / F 6989 / LM4F Stellaris 2.

    Ultra Low Power

    @@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 P2.7 output port IO bits. This will do something else ! From the 2553 data sheet, Port schematics, pages 53 + ..... For P2DIR BIT6 set - P2.6 will become Timer0_A3 TA1. (assuming that P2SEL 6 is still at '1' ) And P2.7 will be XOUT. Just so you are aware..... tcheuss,

    Ultra Low Power

    @@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) - you are not using Energia (IDE as you described above) Cheers,
  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 to Friday 29 Jan 2016 ============================================ I am indeed able to compile and download the 'blink.ino' sketch into the 432LP, but only when working as follows: - using CCSv6 desktop - creating a new Energia project in CCS6: copy / paste 'blink.ino' - CCS build (hammer icon) / debug (bug icon) And this downloaded 'blink' into the 432LP. NOTES: - I got compile errors during CCS build of 'blink'. No line numbers were indicated (red spot on right) - ignoring the CCS build compile errors, I launched a debug session. My 432LP red LED now blinks. >>> I find this quite surprising <<< TRIED / RESULT ============== Chronologically: 1 -- ran CCS cloud -- selected 432LP, loaded 'blink', ran it -- loaded / ran 'ticloudagent__2__xds110_drivers.exe' as requested by CCS cloud (I am not convinced this loaded properly) -- again, ran 'blink' in CCS cloud / Energia, appeared to compile OK, waited forever to download, no 'crash' messages. RESULT : not working. My PC hung on what I think was the download. ====== 2 -- basically repeated step 1 in different flavours. RESULT : as above. ====== 3 -- GOOD NEWS - Loaded Energia sketch into 432LP while running under CCSv6 -- I figured this was a good idea since CCS desktop loads into the 432LP every time, using its DS server version. (in spite of a DSLite.exe file in CCS directories (as I reported), I cannot confirm what module is loading the LP) -- I created a new CCSv6 desktop project, Energia type. -- copy / paste the 'blink' sketch -- CCS 'build' (hammer icon) -> this got some error reports in the console window, but no 'red dots' in the text. -- CCS 'debug' the sketch, the download reported OK in CCS console, hitting 'resume' (|>) got the RED LED blinking. See Addenda 1, below. NEXT STEPS ========== - try a few more, but more complicated, Energia sketches under CCSv6 - try the CCS debug features on an Energia sketch under CCSv6 CONCLUSIONS =========== 1 -- My personal workaround for this problem is to use CCSv6 desktop for Energia projects. In addition to using CCSv6 for my straight-C projects. 2 -- I still think there is something, likely pretty simple, lurking in DSLite.exe while running E17 standalone. I see some concerns on e2e and this forum on loading 432LPs. 3 -- I hope that the CCSv6 destop version maintains its 432LP and other Launchpad loaders intact as it works for me! Well, that's it for now, and I hope this helps. Have a good weekend ! ------------------------------------------------------------------------------------------------------------- ADDENDA: ======== 1-- CCS6 CONSOLE OUTPUT DURING 432LP LOAD ========================================== Here's the CCS6 console output related to the loading of 'blink' into 432LP: CORTEX_M4_0: GEL Output: Memory Map Initialization Complete CORTEX_M4_0: GEL Output: Halting Watchdog Timer CORTEX_M4_0: Flash Programmer: Erasing main memory CORTEX_M4_0: Flash Programmer: Writing 26116 bytes to flash memory 0x00000000 CORTEX_M4_0: Flash Programmer: Writing 2884 bytes to flash memory 0x00006604 CORTEX_M4_0: Flash Programmer: Writing 8 bytes to flash memory 0x00007148 I am amazed why 26116 bytes was loaded to flash at location zero.

Observation: While using the 432LP on CCS6.1, something obvious occurred to me --- that I'm able to load code into the 432 LP each and every time.

    @@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 investigation I'm doing around : -- DDS - AD9850 module and breadboarded cousins: AD5930 (sweep); AD5933 (impedance); AD9834c (DDS); AD9835 (DDS). -- 'clock generator' Si5351 - a rather interesting, tiny device with 3 high frequency outputs and an I2C interface. -- analog PLL - own designs. 1- Spectral performance of AD9850 sine wave. Attached is a screenshot of the close-in spectrum output of the AD9850 as measured on a high-end-hobbyist SDR (software defined radio). Although the sinusoid AD9850 on a scope can look nice, a spectrum analyser can show us a bit more. Some notes.... a) The SDR is tuned to 7,000,000 Hertz with resolution bandwidth at 0.5 Hz, so two spectral lines are 1.0 Hertz. (yes, RBW = 0.5 Hz !) The DDS output has been trimmed (see 2a, below) and is seen to be about 1 Hz lower. The SDR frequency readout had been previously trimmed against a time-and-frequency standard long wave transmitter. B The fundamental DDS output at 7.0 MHz is at -60 dBm. Vertical divisoins are 10dBm. c) Spurs (spurious) frequencies are seen at +- 100 Hz consistently around 7.0 MHz. These are -90 dBm, only 30dB down from the fundamental - rather strong, but can be typical for such a DDS setup. The other two spurs come and go at other DDS fundamentals. (DDS spurs are complex, BUT - Analog Devices has a nice spur calculator with graphics of the step-waveform and the resulting spectrum) 2- MSP430/432 code size reduction. Integer arithmetic. Using integer arithmetic to generate the AD9850 frequency word. I also started with floating point. For the 2553, the flash saved is important. This line of code worked on both the 2553 and 432 in CCS: (not tested for overflows across all input to this function call). void sendFrequency(unsigned long frequency) { int b; P4OUT &= ~DATA; // use DATA line to time the following calculation P4OUT |= DATA; unsigned long freq_32val = ((frequency * 4294967296) / 125001340) ; // nominal 125000000 xtal P4OUT &= ~DATA; Some things to note: a) - the DDS clock divisor is 125,001,340 MHz instead of the nominal 125MHz. This was determined empirically and is important for accuracy. This offset from nominal will be measured periodically with respect to temperature and stored in a 2553 Flash Info Segment. SW trim. B - code size : On a 2553 in CCS6.1, this calculation, setups and a few blinking LEDs was around 2.2 K bytes c) - execution time : the same setup as in B , with the 2553 set to the calibrated 1 MHz clock. The DATA line was raised during the routine's execution ... Time = about 13 mSec, I recall. 3- Environment - coded for MSP430G2553 LP (Energia17 and CCS6.1) and MSP432 LP (CCS6.1) - SDR receiver and spectrum analysis on 'Perseus SDR' - signal coupling from the AD9850 to the SDR was through the air - about 50 cm distance. The SDR was connected to a short outdoor antenna, so the (quiet) background level of about -110dBm is local airwaves. None of this is particularly new, but I hope someone will find this writeup of use. This is intended for learning, possibly make a small, battery powered signal generator for my workbench. As such, next steps are: - test other devices (esp Si5351) - LCD freq display - UART interface - rotary encoder freq knob - attenuator - etc .............. all driven by the MSP430/2 Cheers,

    MSP432 ADC14 Energia Strangeness

    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,

    Multisensor Data acquisition through DMA UART

    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.
