I've got a pretty simple project, connecting an LIS3DH accelerometer to an MSP430G2553 (using MSP-EXP430G2ET). Here's the code: #include <stdint.h> #include <msp430.h> #define SLAVE_ADDR 0x19 int main(void) { WDTCTL = WDTPW + WDTHOLD; // Stop WDT __disable_interrupt(); // Just polling for now // Set to 1 MHz operation BCSCTL1 = CALBC1_1MHZ; DCOCTL = CALDCO_1MHZ; // Configure P1.6 and P1.7 as I2C SCL and SDA respectively P1SEL = 0xc0; P1SEL2 = 0xc0; // This byte is signed for some reason. P1.3 is the button input. P1DIR = ~

Hello! I've got a problem when I want to show the output on serial monitor of a GPS. When I put a basic example (fade example) and the TX of the GPS on the TX of MSP430 (P1_2 pin) the output shows good, without any problem. The baud rate was the stock one (9600). When I try to make the same thing on other pins (I've choosed RX of GPS to P1_3 and TX of GPS to P1_4) a scrambled output takes place on the serial monitor and I don't really know what to do. I'll attach the code, maybe it's a code issue. Thanks in advance! I'm new in this so take me easy p

Hello, I found an Arduino library for tea5767 module. Has anyone tried to import it on Energia IDE or at least has an idea about how can I do this? I work with msp430g2553. Please help me!! https://github.com/andykarpov/TEA5767

I have to ask if someone knows better. If I have MSP430G2553 controller but in CCS I forget to change the settings for controller and there was chosen the G2453, which is the 8KB version of the same controller..does this somehow damage the controller when I program them? They seem to work but I am not sure if this can cause some surprises or failures as it may happen accidentally when using different controllers??

The goal of this project is to utilize an MSP430 to allow existing remote-controlled outlets to by controlled over Wi-Fi. As purchased, the outlets can be controlled with a provided remote control which uses 434 MHz radio signals. By programing the MSP430 to replicate the signals from this remote and hosting a web page with controls on the MSP430, the outlets can be able to be controlled from anywhere on the same Wi-Fi network. The completed project provides a web page that can both control each of three outlets individually or all three at once. This is done using an MSP430 as a controller wi- 1 reply

I am trying (for quite long time) to write to EEPROM 64 bytes of data in 4 chunks (as EEPROM's page size is 16 bytes). Unfortunately, the MCU sends few extra bytes every time it transmits. For example, if I send 16 bytes, it transmits 22, with 6 last bytes being of unknown origin to me. For example, I send 15 text bytes within for(...) cycle xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx but see on the scope xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx BF F6 FD D7 3A C0 I tried another approach: send 15 bytes + 00. My program stops at 00, then I try to replace 00 with wh -
Hi all. I have been working on a fingerprint based project using adafruit's fingerprint scanner from here http://www.adafruit.com/products/751 . I have been successfully using this with Arduino uno with the help of the following library provided by adafruit itself, from here: https://github.com/adafruit/Adafruit-Fingerprint-Sensor-Library Now, i have to switch from Arduino to Msp430g2553 LP. Can you'll please guide me with the following? : 1) How to port This library to Energia? I know the basic part is to replace Arduino.h and associated code with #include <energia.h

Hi... So let me ask this straight. I have to run a 3phase BLDC Motor using a full bridge inverter. The PWM signals for the switches of the inverter need to be generated using a microcontroller. Which means I need 6 different PWM signals. Can this be achieved using an MSP430g2553 chip? I currently have the 20 pin version only. I happen to be a complete beginner in the matter of microcontrollers. So please be kind enough to overlook my dumbness if I've missed out something very obvious! -
Hello fellows, I need some help, i have get a code http://store.43oh.com/download/uploads/TheTerminal-OLEDDisplay/code/GWDeveloper-OLED_MSP430_USCI.zip. Now I have made some changes and I get the code working correctly, This display shows 4 lines of 8 pixels each, the code is implemented to work with a 6x8 font that is displayed correctly. I need to run a larger font, can anyone help me to rewrite the source code correctly that allows me to view a larger font correctly.

Hello. I have wrote an Energia program for digital potentiometer control. I want to save variable "counter" (it is an integer number from 0-255) in non-volatile memory using mspflash.h library in case of reset or power interrupt. But it doesn't saves. I am allmost sure there is something wrong with initialization of variables or pointers inside my code. Can anyone help? Any improvements in code? My code: #include <SPI.h> #include "MspFlash.h" #define outputA P2_1 #define outputB P2_2 #define flash SEGMENT_D int aState; int aLastState; const in

This is my first attempt with Energia. Sorry to ask so many questions. I need to know what state the G2553 is left in after whatever Energia does to it automatically so I know what I need to do, such as: Does it set the top of the stack? Does it set the clock to 1 MHz? 8 MHz? Does it disable the watchdog function? Does it return P2.6 and P2.7 to GPIO use? Does it leave all port pins as inputs with PU resistors? Does it set up a timer to generate interrupts for millis()? Also, where can I find this kind of information? I didn't have any luck searching for

I believe to have all connections correct from the launchpad to my breadboard, but when I connect VCC to my board the LCD just flickers some vertical lines and then the LCD goes dark again. Anyone have an suggestions? /* The circuit: ================================= LCD pin Connect to --------------------------------- 01 - GND GND, pot 02 - VCC +5V, pot 03 - Contrast Pot wiper 04 - RS Pin8 (P2.0) 05 - R/W GND 06 - EN Pin9 (P2.1) 07 - DB0 GND 08 - DB1 GND 09 - DB2

Hi Guys! I have MSP430 EXP LauchPad for my course. I want to program this lauchpad on Linux Mint but I have some troubles about that. Firstly, I downloaded Code Composer Studio to work on it but I had a error about port FET. Now I decided to download Energia, it looks like arduino IDE that is why I know about cart and port settings. My trouble on Energia is on the picture:

Hi everyone I am beginner and I want to use the adxl345 with msp430g2553 with I2C, but the example that I am using don´t working, always send 0 in the axes x,y and z. I use energia 1.6.10e18, the circuit have the pull'up resistor in SDA and SCL pines, and I remove the jumper of the green led. I used the same code but with arduino and it working but with enegia not, help me please. My launchpad is MSP-EXP430G2 rev 1.5 The SCL is connected in pin 14 and the SDA in pin 15. My OS is windows 7 When i put this function "Wire.setModule(0)" the mcu does make nothing, the uar

Hi, When doing offset calibration for pH sensor in Arduino we bring pH 7 to 2.5V as Arduino analog output is 5V. Does that mean when the same is done with msp430g2553 the voltage be adjusted to 1.5V as msp430g2553 analog pins output around 3V only? When I tried adjusting the pot I could only bring it to a minimum of 2.5V with msp430. Does anyone know why? Thanks.

I'm trying to create a toggle button but the code is not working. The code is as shown below: #include <msp430g2553.h> int main(void) { WDTCTL = WDTPW + WDTHOLD; // stop watchdog timer P1DIR &= ~BIT3; //P1.3 i/p P1REN |= BIT3; //P1.3 enable pullup resistor P1IES |= BIT3; //P1.3 high to low transition P1IFG &= ~BIT3; //P1.3 clear interrupt flag P1IE |= BIT3; //enable P1.3 interrupt P1DIR |= BIT0; //P1.0 o/p P1OUT &= ~BIT0; //clear P1.0 _BIS_SR(LPM0_bits + GIE); //enter LPM0 with interrupts enabled } #pragma vector = PORT1_VECTO

I am trying to establish SoftwareSerial Communication between 2 msp430g2553 units. I have connected them as follows: GND to GND, RX to TX and vice versa. MSP1: P1_5, P1_7 //Rx,Tx MSP2: P1_5, P1_7//Rx, Tx , I hope the connection is all right. Now, I want to send a byte from one mcu to the other for which I write the following code: Send function: void sendrequest(){ byte option = 1; mySerial.write(option); delay(2); return; } void loop() { // put your main code here, to run repeatedly: if(mySerial.available()>0){ checkiffalsesignal(); delay(10000);

I had a HDC1080 EVM. I read that the back end of the evm can be broken off from the perforation and used as a standalone sensor on a micro-controller. I tried to interface it with the MSP430G2553. I have done the following with no avail: 1) the jumper on P1.6 has been removed(no interference of led with SCL line) 2) I have tried using pullup resistors on both the SCL and SDA lines. I have tried out with the standard 4.7k resistors and also with 10k resistors. 3) I always get a temperature value of -40 degree C and humidity of 0%, which means that the MSP is not able to

I am trying to implement the msp430g2553 on a breadboard. Where should I add the reset button. I am not sure, but I think it should be added between reset pin and ground. BTW, I have the msp430 working on the breadboard, 47k between RST and Vcc and 1 nF between RST and GND. Where to add the pushbutton? The pushbutton is really handy for resetting

I have been trying to interface DHT11 sensor with MSP430G2553. But I always end up getting a checksum error. I have attched the code and the library I am using. My sensor is the normal one with 4 pins coming out of it. I connect pin1 to Vcc(3.3V), pin2 to data pin(P1_3) and pin4 to GND. Please help. #include <dht.h> dht DHT; #define DHT11_PIN 5 void setup() { Serial.begin(9600); Serial.println("DHT TEST PROGRAM "); Serial.print("LIBRARY VERSION: "); Serial.println(DHT_LIB_VERSION); Serial.println(); Serial.println("Type,\tstatus,\tHumidity (%),\tTemperature (C)"); }

I want to interface a DHT11 temperature and humidity sensor with my MSP430G2553. I looked up the Energia list of libraries, but the link for DHT11 is currently inactive. I tried downloading libraries from github, even ported over libraries from arduino, but none of them are working. I either get timeout errors or nothing gets printed on serial monitor at all. I know for sure that my sensor is perfectly fine because I have tested it for multiple libraries on Arduino. Please provide me the link for a valid DHT11 Energia library or help me out otherwise.
