  1. Hi, i'm trying to run AT commands on HC-05 connected to MSP430G2553. The code below works on Arduino but i need to do it with MSP430. I changed the pins to match the MSP, tried to run the code but i see nothing on serial monitor. Total noob here and needs help. #include <SoftwareSerial.h> SoftwareSerial BTSerial(3, 4); void setup() { pinMode(9, OUTPUT); // this pin will pull the HC-05 pin 34 (key pin) HIGH to switch module to AT mode digitalWrite(9, HIGH); Serial.begin(9600); Serial.write("Enter AT commands:"); BTSerial.begin(38400); // HC-05 de
  2. Hello, I using library to read values etc. written by Mr. Jarzebski . https://github.com/jarzebski/Arduino-MPU6050 After attaching servo to a pin, and after compile and runing the program works a couple of time (2-40 seconds) after this time the program frozing. I dont know why Servos and Gyro disrupt themself.
  3. I've been trying to get an Energia sketch for the MSP430FR5994 LaunchPad Development Kit to work with a custom board I made. I used a different MSP430FR5994 package than the one on the launchpad so I need to change the pins used. It sounds like typically the way to do that is to create a new board variant with its own pins_energia.h file with the pins changed. But, it looks like the FR5994 version of the file doesn't map the pins to the actual chip, but to the booster pack headers on the development kit, implying that those are mapped to the actual chip pins somewhere else, but I can't find wh
  4. I would like to locate code (or data) in upper FRAM using something like: void __attribute__((section("REGION_FAR_TEXT"))) myFunction(void); This should be possible because Energia for MSP430 memory.x files have a line REGION_ALIAS("REGION_FAR_TEXT", far_rom); and far_rom is declared as: far_rom : ORIGIN = 0x00010000, LENGTH = 0x00004000 /* END=0x00014000, size 16K */ but this was not working back in Energia E20. Is this working now in Energia E23?
  5. MSP430 based Nixie tube clock. I was looking for some nice Nixie tube digit images so I could add them to my EduKit library, but I couldn't find any usable ones. I decided to just buy few of them and photograph myself. Then I thought that it would be a horrible waste if they just sit in a drawer. So here it is, my first Nixie project since... 1987. This clock will be available as kit, but since this is v1, I will most likely make some adjustments. Any suggestions are welcome.
  6. (Context: I'm an experienced embedded systems engineer, just dipping my toe into MSP430-land. My target system is an MSP-EXP430FR5994 LaunchPad dev board.) General goal: How do I wake the processor N ticks in the future, where one tick is 1/32768 second and N can be as large as 2^15? My first thought was to use the RTC, but that appears to have a resolution of 1 second. My second thought was to use a timer module (e.g. TA1) and use its compare interrupt to wake the processor from LPM4. So my questions: Is there a better / alternative way to wake the processor N ti
  7. I got an MSP-EXP430G2ET yesterday, and after installing drivers and Energia (Debian unstable) I plugged it in and opened up the blink example. Energia spat out some messages about the firmware needing updating, and started the process. I don't have the log (it's fallen off my console's buffer) but it did not appear to complete successfully. Now, when I try to use Energia to flash the blink example, I get this: Sketch uses 386 bytes (2%) of program storage space. Maximum is 16384 bytes. Global variables use 20 bytes (3%) of dynamic memory, leaving 492 bytes for local variables. Maximum is 5
  8. I'm trying to use the UCA0 for SPI on MSP430FR2433 by using the SPI.setmodule(10); before SPI.begin(), but I'm not getting any data on the SPI lines. The default SPI on this launchpad is UCA1 and it works. After the above thing didn't work, I tried changing the core files: /home/username/.energia15/packages/energia/hardware/msp430/1.0.5/variants/MSP-EXP430FR2433LP/pins_energia.h In this file I changed: (from line 47 to 50) static const uint8_t SS11 = 8; /* P2.1 */ static const uint8_t SCK11 = 7; /* P2.3 */ static const uint8_t MOSI11 = 15; /* P2.4 aka SIMO */ static const
  9. Hello guys,i have a question for my project im using the msp430g2231 microcontroller and i want to measure frequencies up to 10Mhz.Im new to microcontrollers(not programming),and im not sure how to make the overflow work void main(void) { WDTCTL = WDTPW + WDTHOLD; // stop watchdog timer BCSCTL1 = CALBC1_1MHZ; // Set range DCOCTL = CALDCO_1MHZ; // Set DCO step + modulation delay(100); // delay 100mS until next screen refresh /*** Timer_A Set-Up ***/ TA0CCR0 = SampleTuneTime; TA0CCTL0 |= CCIE; // Interrupt enable
  10. Hello everyone, I am just a beginner in using MSP430, I want to know how to design a circuit of motion detection system. I have the ports which LCD display should be connected to , So I want to check if they are correct, since all of this is new to me. for LCD display port connection. connect RS to P2.5 connect RW to P2.6 connect E to P2.4 connect D0-D3 to NC connect D4 to P2.0 connect D5 to P2.1 connect D6 to P2.2 connect D7 to P2.3 are the above correct? where should I connect PIR sensor? please, I nee
  11. Hello, I am storing a sensor value in the Flash Memory in a Segment of MSP430F5529 board. Since the data from the sensor keeps changing i want the data to be overwritten so that not much of space in flash memory is used. Is there a simple way to achieve the overwrite feature in flash memory ? Also i have another doubt, i wanted to know if i keep writing continuously a data to flash memory, does the microcontroller gets caught in writing to the flash and slows the running program ? thank you for taking time to review my questions.
  12. so we were trying to code msp430FR5969 but we got these errors and now we dont know that how to solve it and one more thing are ltc libraries and linduino libraries compatible with energia and if not then what is the other method in which we can code them using msp430
  13. Hello, Has there ever been a method developed for Energia that allows it to use an external crystal? I'd like to have the ability to enable a low frequency crystal as well as a high frequency crystal on the msp430fr5994. Does anyone have any recommendations for implementing this? Thanks,
  14. Hello, I'm trying to get some code to upload to my MSP-EXP430F5529LP board. Following this forum post (I'm on Mac OS Catalina), I installed a pre-release version of Energia, and I get this error: Energia: 1.8.10E22 (Mac OS X), Board: "MSP-EXP430F5529LP" Sketch uses 706 bytes (1%) of program storage space.

  15. Hello, I've been developing with the msp430fr5994 on energia and I seem to have come across an issue using the serial ports on 6.0 and 6.1 I have two of these processors connected together with the Tx/Rx connected respectively on 6.0 and 6.1. I have the first processor sending out a single number using the Serial1.write("1"); command. The second processor i set to respond by displaying data on it's TFT once it gets any kind of data. So far, I can't get anything to come out of the Serial1 ports. An oscilloscope shows that it's being held high and not sending any kind of data out. I've trie
  16. Howdy, I'm having trouble programming my MSP430FR2433LP with Energia on my Mac. When I try to upload the program, it gives me this error: MSP430: Error initializing emulator: No USB FET was found. Strangely, I am able to program it with the online Code Composer Studio. I have made it blink red and green lights. Unfortunately, I'm not trying to become an embedded programmer (while that would be fun, I do not have the time) so I do not want to learn CCS, registers, and serial communications in pure C. Props to all you who can do this. I really want this to work
  17. I an using mspexp430g2 launchpad on energia with windows 10 OS.In this while compiling the inbulit "DigitalReadSerial" example code from energia IDE ,at that time it should print the output in the Serial Monitor screen . But it does not print anything.Please help me.
  18. From time to time, threads pop up where someone tries to count very fast pulses in the hundreds of kHz or even MHz range. There is a solution for the hardcore C-coders among us, but to my surprise there was no Energia library for this simple problem. I herewith present the CounterLib for Energia Download Source code and detailed instructions are also available on GitHub: https://github.com/astuder/CounterLib-Energia Currently the library supports MSP430G2553, MSP430F5529 and MSP430FR5969. To create an instance of the counter, simply declare it as a global variable like this:
  19. Hello, I've been pulling my hair out trying to get these libraries to compile in Energia for the msp430fr5994. Is there anyone here that might be able to help me port these libraries? I feel like its just about changing some of the declarations and specifics but I don't even know where to start. I would appreciate any help or advice anyone can give . Thanks, CFAF240240A1-013T_Arduino (3).zip
  20. 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
  21. So I have to figure out a way to connect my MSP430f5529LP to a local broker on a Raspberry Pi through MQTT. It is important that I use an ESP8266 as CC3100BOOST would cost me like $50 over here when I can get an ESP8266 for like $4. I went through various pages and stuff in search of codes and libraries and couldn't find a single one. This is part of my college project and I really need to get this done. Does anyone have any idea on how to work with ESP8266 for MQTT using AT commands as it is my last resort as I can't find any libraries for MSP430. And BTW, TivaC would also suffice. The b
  22. Overview dAISy (do AIS yourself) is a very simple AIS receiver that I developed from scratch. It is built around the Silicon Labs EZRadioPRO Si4362 receiver, using a Texas Instruments MSP430G2553 MCU for processing and the MSP-EXP430G2 v1.5 LaunchPad as development platform. The complete project source code and schematics are available on GitHub: https://github.com/astuder/dAISy Update 5/18/2015: A finished, self-contained AIS receiver based on this project is now available for purchase in my web store. AIS, short for Automatic Identification System, is a standard for tracking ship
  23. Hi all, I have recently acquired a color click board (https://www.digikey.co.uk/en/product-highlight/m/mikroelektronika/color-click-board) and would like to get it working with one of my MSP430 Launchpads. A sketch already exists for the Arduino (https://github.com/raivisr/TCS3471-Arduino-Library/blob/master/TCS3471/examples/ColorSensor/ColorSensor.pde) I have tried porting it over to MSP430, but have been unsuccessful. Do you have any suggestions as to where I may be going wrong? Problems are with undefined references. Thanks!
  24. Hi, I am using Energia 1.8.7E21. I am interfacing a HX711 Weighing Scale kit to MSP430FR5969 Launchpad. I am using a Energia Code that worked at another weighing scale project more than a year ago. When I program it, it runs 1 time and I see the output at Serial Console. But when I program again there is no output. Out of 10 programming the first one only has output. The rest do not have output at Tera Term. To confirm that the program does not run I put a code to turn on the red led. But the red led did not turn on. #include "HX711.h" #define DOUT 5 #define CLK 6 // most launch
  25. Hello everyone, I would like to know how can I get digital input working under Simulink Embedded Coder Target for Energia. I had successfully used the digital output block in my Simulink models with MSP-EXP430G2 Launchpad, but didn't succeed for the digital input. Does the digital input block require external mode to operate? Please help
