  1. The output of MSP430G2231 38KHZ 1% duty cycle?
  2. Being a beginner, i am facing an issue with operating frequency of MSP430G2231(hereafter G2231) board in energia. If i am operating G2231 at 1MHz frequency, it takes nearly 2.5 sec to wake up from reset. In order to reduce this wake up(turn on time), i edited boards.txt (available in energia folder under hardware. File is attached) to operate at 16MHz. But it happened totally opposite and now it takes nearly 40sec to turn on from reset. Can someone point out my mistakes? I need to reduce this wake up time. If there is any other way to do it, kindly suggest me that. Thanks in advance.
  3. So now that that CCS 6 includes a "released" msp430-elf-gcc, I thought I'd share my ultra small c-runtime startup code as an exported CCS project. This will be useful to those who want to use the free msp430-elf-gcc with the smaller chips like an msp430g2231. Also, it is an exercise to see if I can share exported CCS project files that will be usable in Windows even though I'm using CCS v6 on linux. Just download the attached zip file and then use the "Import Project" button on the "Getting Started" page in CCS. It should import the zip file into a new project in your workspace called "
  4. This is very much in progress, and there's nothing fancy about it, but I wanted to share with you what I'm working on at the moment since I'm back into the 430 again after a while in arm/linux land. Only the relay stuff is implemented for now and the master is currently just a test which advances the relay selections by push of the s2 button. Criticism, ideas and insults welcome I would like to do various slave firmwares for sensors, etc and I will be incoprorating also a BBB controller at some point. Code shamefully stolen/modified from TI examples. Master.c //*************
  5. Hello every one, I have a Infrared TSOP sensor and i want to use it with MSP430G2231 to decode IR Remote codes but, when I try to compile the example codes errors appears during compilation. i need suggestions to correct the library files....
  6. Hey All, I tired to write a code, just check it out and tell me whether it gives out a LED glowing MSP430 or no. I know i am bad coder but i am learning it. Code is attached below. Tell me what all i should add in it. Thanks And Regards Msp.txt
  7. Hey All, Hieeeee When i am debugging my code, it is giving a error called Multiple markers at this line - <a href="file:/D:/code%20composer%20studiov5/ccsv5/tools/compiler/dmed/HTML/MSP430/1527.html">#1527-D</a> (ULP 2.1) Detected SW delay loop using empty loop. Recommend using a timer module instead - #20 identifier "ADC10TL1" is undefined ON THIS LINE while(ADC10CTL1 & ADC10BUSY); Thanks in anticipation Nikki
  8. Hi All, I am very new to MSP430G2231,Can you please guide me how to manually connect the ds1307 to launchpad as i have nly 14 pins. And how i can generate a interrupt at 10'O clock and 2'O clock everyday reading a time from real time clock through code(embedded C). In between what all i should take in my coding part. Hoping to get guidance Thanks in anticipation Nikita.
  9. Hello MSP430 coders once again i am working on the latest thing such as take input from the Hyper terminal or Putty, and display it in jhd162a (16x2 display) via MSP430G2231 I successfully finished 1. UART with Hyper-terminal 2. Displaying String to JHD162A the problem i am facing in g2231 is .. i am able to print String only like .............taking example printf("Hello this is launchpad"); but i want to make it print like int i = 0; for(i=o;i<=200;i++) ( printf("The number is : %d ", i); ) i am giving you scenario so i take the printf Example ..
  10. Yet another software only serial class implementation? What makes this one different? C++ template based with asm routines to implement read and write. Works with any pin and port combination. You can mix and match, put read on P2.0 and write on P1.2. Small size even with Energia. Multiple instances allowed. Each instance uses about 12 bytes so you are only limited by the number of pins and memory on your chip. Big plus, doesn't use the timer. Read on if this piques your interest. This code implements a C++ template based software only blocking serial UART class. It doesn't use the timer peri
  11. Hi all, After a little help with some PWM code, the code is below and the areas I believe to be the main issue are in bold. I basically have 2 LDR's linked up to P1.1 and P1.2, then I would like to have 2 PWM outputs on a further 2 pins say P1.4 and P1.5. The code below is working as far as the ADC and changes the brightness of an LED on P1.6, but I am struggling to have any output on another pin (currently trying P1.5). I have been looking at the TI PDF's slau144i and the MSP430G2231 datasheet, but still unsure how to approach this. There is another small question regarding the
  12. Hello MSP430 Coders i have finished all the basic modules, now i stuck in to uart. i need some ideas from your side,( if possible please give me code also :-P ) my Launchpad send signal to print numbers like 1,2,3 ... for every 1 second delay, numbers should be printed in to hyper terminal. what will the pin connection for the launchpad, Jumper setting and the most important thing is how the launchpad will work. Thanks you all.
