  1. Someone can helpme, i'm taking incorrect readings of a magnetometer I believe with the problem are in my i2c code implementation. /* * Print all printable characters on usb channel using UART mode of USCI module * the print is based in busy wait to transfer characters */ #include "msp/msp430g2553.h" void configureDCO(); void configureUART(); void putc(char); void print (const char[]); void print (short); void printStatus(); main() { configureDCO(); configureUART(); UCB0CTL1 = UCSWRST; //Reset USCI UCB0CTL0 = // USCI_B0 control register UCMST
  2. Hey Guys, I am new user of Energia. Currently, I am using MSP430G2553 chip to write data in SD card. I found code that works on USCIB0 SPI communication. Here is the link for the code. This code works completely fine. But, I wanted to know how can I change the code to use USCIA0 SPI instead of USCIB0 to do this? I tried going into pins_energia.h and just changing the pins. But it didn't work. Can anybody help me with this problem? Here is port assignment for different SPI buses USCIB0: (Code is using it) P1.6 -> master in slave out (MISO) P1.7 -> master out slave in (MOSI)
  3. Hi, everyone. I want to do a light web server (show temperature value and port control) with MSP430g2553 and ENC28j60 Breakout Module. At this forum, there are many examples about this issue using Energia lib. But I want to use IAR Embedded Workbench as IDE, not using Energia lib.So probably MSP430 and ENC28j60 communicate using SP?. How I do this project at IAR Embedded Workbench.Thank you
  4. Hi guys. For those who like 7-segment led displays, here is easy to use booster pack with digits! It has driver ic to control display and read buttons using I2C. Also is can be topped up with on board EEPROM, TMP102 sensor, Seiko RTC Crystal and 3.3V regulator. And this booster pack can be used standalone also. If you like it and want to get one, please support at Tindie.com Pictures are from prototype.
  5. Hi, everyone! (I'm completely newbie, so excuse me if my questions are stupid) I made my first "device" (pic related). It works fine for a short period of time (like an hour or something like that), but then it goes crazy: led start blinking all the time and device don't respond when I change temperature. Could you please tell me, what's wrong? (I tried both - CR3024 battery and 3.3V power supply) #include <msp430.h> #include <RTCplus.h> RealTimeClock rtc; //initialise the global RealTimeClock instance int sensorPin = A3; // select the input pin for the potentio
  6. Hi Everyone, I am using LED blinking program of Arduino on MSP430. I have configured compilers etc. Now the led turns on but it is not blinking. I have tried changing delay/sampling rate. Can someone point me the issue here?
  7. Hello, I am trying to have my MSP430G2553 on a launchpad (Rev.1.5) show anything on the serial monitor using the following code: void setup() { Serial.begin(9600); } void loop() { Serial.println("Test"); delay(1000); } I have downloaded the drivers http://energia.nu/Guide_Windows.html I have switched the jumpers http://energia.nu/img/LaunchPadMSP430G2553-V1.5.jpg I'm just not sure what is wrong. I can load the Blink example and get it to work and even making it do other things but when it comes to reading values and serial the launchpad doesn't want to do anything.
  8. Hi! I tried to connect GPRS Shield from Arduino to msp430g2553 with SoftwareSerial library. But I faced with the problem. When the size of sketch exceeds 5590 bytes, global variables do not work. I just add one variable (global string) and the program stops executed correctly. Here is the code: /* When new serial data arrives, this sketch adds it to a String. When a '!' character is received, the loop prints the string "Hello world!" */ #include <SoftwareSerial.h> SoftwareSerial mySerial(P2_0, P1_5); String inputString = ""; // a string to hold incoming data boolean st
  9. I have the MSP430G2553 on the launchpad and a CC2530DK_EM on an EM Adapter BoosterPack (BOOST-CCEMADAPTER). I was wondering what is the best way to code these devices. Should I be using CCStudio or Energia, and where can I find more information about programming these devices so they can use Zigbee communication?
  10. Hi all, I was playing around with the MSP430G2553 and the UART at the weekend, then remembered I had a cheap HC06 bluetooth module. The result being a basic Android app that you can control your launchpad using voice control, it's far from polished but a bit of fun all the same Project tutorial.

  11. EDIT: Now on Tindie I have 2 new boards coming soon: GPS BoosterPack and standalone board. They will (most likely) come with pre-soldered and tested GPS module, and possibly as a kit. Standalone board has a socket and all necessary part to use it with MSP430G2553. The price of BP is $22, SA board will cost ~$25 (MCU not included.)
  12. hello friends, I have a big problem with small MSP430G2553, I would like to make a capture samples at P1.2 of the microcontroller, but my code does not work, what am I doing wrong, can someone help me. My code: unsigned int adcValue = 0; int i, BPM[10]; int maior = BPM[0]; int menor = BPM[0]; int contagem =0; /*****************************************************************/ /********* LOCAL FUNCTIONS *********/ /*****************************************************************/ void ADC_ConfigAnalogInput(void){ P1DIR2IN(BIT0); ADC10CTL0 &= ~(E
  13. Hello guys, I'm building a Holter ECG, and would like put one symbol on the LCD. Need to inform the user the level of charge that the battery has. And I would put the battery symbol so that information was given. But I am not getting, someone can give me an example of how I can put a symbol in a particular line of lcd
  14. I loved the eZ430-Chronos. On the Internet many projects made ??on the basis of this development tool. But one thing I did not like is that you need a computer to manage their programs. And without a computer Chronos watch can not control anything. So I bought Anaren CC110L RF BoosterPack (868 Mhz). But this kit does not work with Chronos. I looked a lot of information and code on this forum and on the internet. But always something was wrong, I did not want to rewrite the SimpliciTi protocol. And finally... I did emulation of RF USB dongle. The project uses the unmodified Chronos Control
  15. First of all a question, I just have to change the jumpers J3 connections if I use serial communication right? Hello, I've a project where the msp430g2553 makes an access control by password. The launch pad receives a password from a matrix keypad, and turns on a motor to lock the door, or to lock the door if a button is pressed from inside the "room" The project works fine, but sometimes the dc motor doesn't stop working, and it is happening randomly. can somebody help me? sorry for my terrible english the code and a circuit layout: /*lock door control*//* matrix keypad: S
  16. Hai I'm a complete newbie to Energia and MSP430. I would like to get some help on a problem that I'm facing while interfacing MSP430 launchpad using I2C(it's not "a" problem, rather it is "THE" problem). As mentioned above I'm using a MSP430-g2553 launchpad ver1.5 and currently I'm working on a project that requires interfacing two MSP430s with a Raspberry Pi. The protocol that I've chose is I2C due to it's simple hardware requirement and it's support for many devices at the same time. But then till now interfacing two MSP430s has been a faliture. I tried interfacing two MSPs on two launchpad
  17. Can I use AIR430Boost Library for CC2500 module with MSP430G2553. Or do I need to change it? I tried to run WirelessControl example but nothing happened. I hooked up the module to the same pins as of CC110L. I am using Energia 0101E0012.
  18. Hello everyone ! I started to use Energia to create simple projects using MSP430G2553 LaunchPad and somehow I've succeded until now! Today I encountered a problem as I was trying to read values from a HIH-4000-001 humidity sensor.The sensor is powered with 5V and can return a value ranging from 0.826 V to 3.976V coresponding to 0 - 100 % RH. Because 3.976 V is much more than the MSP430 can manage I used a 1:2 resistive divider to scale down the signal.Moreover the sensor needs an load resistance of minimum 80kohms so the resistors I used for my divider were R1= 36kohms and R2

    Just came across this Kickstarter that features the MSP430G2553 LaunchPad and Energia: PicassoBot, the Portrait Sketching Robot Kit. https://www.kickstarter.com/projects/educatedrobot/picassobot-the-portrait-sketching-robot-kit
  20. Hi All, I am using Energia 0101E0012, MSP430G2553, Launchpad G2 Rev 1.4, on a mac. When I run the example MspFlash program, it appears like I erase and write to flash correctly, but when I try to read the "Hello World" written into flash, the only thing that prints out is
  21. ive compiled and uploaded my code (below) and when plug my msp430g2553 in it goes to the programmed angle it should when plugged in, but when i run the exe that is supposed to change its angle it doesnt do anything. the exe is programmed to connect to com4, and the msp430 application uart is set to com4. i know the exe can detect it because it wont run unless it can, it just isnt responding. im am using energia 0101E0010 to compile and upload. any help would be appreciated. here is the code: #include <Servo.h> Servo myServo; const int servoPin = 9; // the pin the servo is con
  22. Hi Everyone, I have been looking for about an hour online and haven't been able to find the answers to these questions. - Can I use floating point with the msp4302553 ? the watch expression on CCS don't seems to like floating point for sure. - Can I use math.h to do trigonometry calculus on the msp430g2553 ? Let me tell you guys what I am trying to do so that it is more clear: I am scanning a signal with an ADC. I would like to do an atan() on the signal and output the signal with an DAC. Right now I can scan the signal and send it to the DAC. This works well. But I can't get the t

  24. hi all, I'm trying to use an Ethernet module that i bought called "Ethernet LAN Module for Arduino / microcontrollers with SPI (ENC26J80)". I found a few example for it for different MSP430's but i cant get it to work. Does anyone know how to make it work? witch pins to connect and example code would be great. thanks, Ofer.
