  1. Hi I am measuring two strain gauges with the first two differential ADC input channels on a MSP430i2041. I would like to measure the temperature of my DUT on one channel. All the app notes I found (SBAA275, SBAA330A, others ) suggest using a current source and then a reference resistor over the positive and negative reference inputs of the ADC. As I use the internal reference of the MSP430 for measuring the strain gauges, I can't exactly go and force another voltage on the reference. As a "cheap" possibility, would it be possible to connect VCC--[10k]--[PT1000]--[10k]--GND
  2. Hello I'm trying to read all the IO from a port (port 2) on my M430G255 MCU . On arduino I could have use the line DDRB = B11111111; data = PINB; I've read some posts but no one talks about port manipulation on energia and msp boards clearly. can someone help me figure out how to woks with registers and msp boards ? thanks EDIT : I found the register file on the energia installation folder, but every time that i try to charge e a register I get the error: expected unqualified-id before numeric constant
  3. Hello there, I connected a gps module and it gives me the gps data but im unable to segregate the following data on energia +QGNSSRD: $GNRMC,044927.000,A,1301.7816,N,07731.3016,E,0.00,93.73,290319,,,A*4F so i need to separate the latitude and longitude, time and date. So can anybody help me in understanding how to get the required data from the above. i attached my code below as you can see im getting stuck in the serial read please help me in correcting this. ? 1 2 3
  4. Has anyone else experienced something like this? I have been using Energia on Windows for years on various LaunchPads, including 430, 432, and Stellaris (now Tiva). The Windows 10 PCs are a Surface Pro 3, a Toshiba Satellite, and an HP Pavilion. Over the last few months, builds and uploads fail in multiple ways unpredictably. The Serial Monitor often doesn't work, even when the TX pin has the correct signal (verified with an oscilloscope decoder). Often the fix is simply to click the Upload button over and over until it works. I've changed to shorter USB cables and switched from USB
  5. Hello, Im getting an error while compiling the 128x64 LCD u8g2 library on msp430fr6989. I tried the hello world code on it full buffer. I complied the same code on msp432p401r it compiled and even the display worked but the same code when changed the board to FR6989 its says fatal error assert.h no such file or directory, the screen shot is attached below. Please help me with it. Thank you U8g2_Arduino-master.zip
  6. I get the error "'SPISettings' does not name a type" when I compile my code for LoRaWAN. The codes are working in Arduino with the libraries LoRa.h and SPI.h. I have added the image to where the error is pointing at (In LoRa Library) and the Error message as well below. I tried changing the energia SPI library to the Arduino SPI library as well but this created more problems. Out of all the things I tried, the most simple error I get is here when it says "Does not name a type". How can I correct that bit of code to get rid of this error. I'm a relative beginner in Energia and no
  7. Hi, I just got the MSP432 and am really excited to start working with this board. I'm running Windows 10 on an ACER Aspire 64 bit machine. Unfortunately when I go to upload a program using Energia the port menu is grayed out. I used to have this problem with the arduino on the arduino IDE until I downloaded the FTDI drivers from: http://www.ftdichip.com/Drivers/VCP.htm The following picture shows the IDE as I see it now: I followed the instructions for installing the XDS110 drivers according to the windows install guide for the MSP432. Checking the device manager I se
  8. As an electrical engineering student at John Brown University, we were tasked with creating a useful product or service using the combined skills gained through our embedded systems class. As someone who likes interior decorating and hates mismatched paint, I came up with the idea to make an RGB color sensor attachment for a camera. Of course converting RGB data to paint colors is not conventional, it is something that could potentially be viable. To make things interesting and for the experience of working with a Raspberry Pi, I used a raspberry Pi camera to act as the base for the project. A
  9. I am using a MSP430FR2311 launch pad and i am trying to send AT commands through RX and TX to SIM800 and Receive Response from the SIM800 module. But am not able to get the response and not able to use SoftwareSerial in Energia for MSP boards. Can Anyone help with this problem ? Thank you in advance. #include <String.h> void setup() { pinMode(RED_LED , OUTPUT); Serial.begin(9600); //Serial.print(F("AT\r")); while(Serial.available()==0); val1 = Serial.readString(); Serial.print(val1); Serial.print("\r"); delay(100); } void loo
  10. Hi all, I need to import/upload data to my MSP432P401R to call upon in future programs. Since I want this data to exist and be saved when my MSP432 is offline/powered-off, I decided that saving it to flash is the way to go. However, I don't know how to do this. Can anyone offer guidance or suggestions? Or does anyone have a better way of doing this? I'm using Energia v18.
  11. Hello there, I am new to this forum. I wanted a code which could help me create a neural network to correlate my sensor data and get the desired output. I am using MSP430G2553 micro-controller with Energia as the software. It will be a great help. Thanks in advance.
  12. Hello everyone, I have a problem with Energia and my MSP430F5529, this micro is enable to use 12bits ADC, but I can't find the way to make it enable that configuration because Energia runs my code in default 10bits ADC, some one can tell me how can I configure the ADC to use 12 bits resolution??, this is my code: #include <Servo.h> Servo servo; int potpin = 23; int volt, i; void setup() { servo.attach(19); } void loop() { volt=analogRead(potpin); i=volt/6; //I'ms using 6, because 1023/6 = aprox ? 180 steps
  13. Hi everybody fooling around with the MSP432 launchpad. Does anybody know how to properly and elegantly use bit banding? Could not find much on the web and in the examples... This does not work, does not even create an error message: // this does what you expect, a short pulse P1OUT |= BIT0; P1OUT &= ~BIT0; // this does nothing BITBAND_PERI(P1OUT,BIT0)=1; BITBAND_PERI(P1OUT,BIT0)=0; does anybody know what I am doing wrong here?
  14. Hi everyone, I wanted some strategic advice from the Forum on an MSP event I'm organizing in Rome next week (everyone is invited, the link is at the end of the post). I'm trying to introduce the MSP hardware/software platform to an arduinocentric audience who is unaware of other - better in my opinion - options such as ours. For the hands-on part, I'm basically going to open up a sketch in Energia - which they will recognize as an "Arduino in red" - and then I want to migrate it into Code Composer Studio, in order to show them what a professional IDE is all about and what it offers. My idea
