  1. Hi all, I have recently found a sketch in arduino forum for frequency counting, which I tried running in MSP432 with energia and MSP430 with energia sketch on Code composer studio. The sketch basically counts the frequency using interrupts and prints the frequency on serial monitor but serial monitor is empty while running the program,.The sketch is as shown below, // Frequency counter sketch, for measuring frequencies low enough to execute an interrupt for each cycle // Connect the frequency source to the INT0 pin (digital pin 2 on an Arduino Uno) volatile unsigned long firstPulseTime;
  2. HI If i import my ENERGIA project to CCS V6.1, can i also use the gui composer for the same project? best regards, avi
  3. Hello, Im working with TM1809 RGB LEDs on an MSP430G2553 over SPI (3-wire) data transfer. Im running into issues with timing and im not sure if its due to voltage or something else, and could really use some help. https://www.deskontrol.net/descargas/datasheets/TM1809.pdf on page 2 says that these lights require 4.5-5.5V, and i know the MSP430 is at 3.3V, is this the reason? My code below achieves the ability to set the RGB LEDs with about 95% success rate, i run into issues attempting to animate the colors or if i send it the same color over and over it will send bad data 5%
  4. Hello, I'm using MSP430F5131 and trying to program it by IAR Embedded Workbench while using the MSP-FET debugger. A short background of the PCB: After i compiled the code in IAR with not errors found , i connected the MSP-FET to the MSP430 in a Spi-Bi-Wire connection according to the datasheet. The MSP430 is placed in a PCB which includes 12V input voltage and 2 regulators of 5V and 3.3V . The MSP430 I/O's are connected according to the datasheet (including external pullup resistors and capacitors) along with the Spi-Bi-Wire connections. I energized the PCB with a 12V supply voltage
  5. Hello , I am using MSP430F5131, IAR Workbench compiler and i have purchased MSP-FET. i have successfully compiled my code in IAR Workbench , although when i try to download the program through the MSP-FET using the IAR Workbench (i have clicked on download and debbug and it has started to initialize the device) i encountered this error : Fatal error: Could not find device (or device not supported) Session aborted! Thanks in advance
  6. hello all !! I'd been worked with MSP430G25530 target for Frequency measurment ... I have a code but, when I use the Serial.print (). nothing show up. any helps please ? my code : Freq-Measurment.ino
  7. This project is an offshoot of an earlier investigation of wireless wearables using the MSP430G2553: http://forum.43oh.com/topic/10060-msp430-wearable-with-radio/. The concept has been successfully tested and is described below. I plan regular updates as the project progresses. The objective is to develop a wearable powered by a coin cell that can be controlled remotely. It could be used, as an example, in the tiara below or on a costume worn by dancers in a performance and controlled from offstage. In the photo an earlier MSP430G2553 coin cell powered wearable is attached to the tiar
  8. Hey everyone, I'm trying to interface an MSP-EXP430FR5969 with a GPS+GSM module (https://tronixlabs.com.au/arduino/shields/3g-shield/adafruit-fona-3g-cellular-breakout-900-and-2100-mhz-for-optus-vodafone-australia/) I've been able to send a text message to my mobile using the Arduino, but when I try on Energia 1.6 with the module now plugged into the MSP430 I get compilation errors (mainly due to atof not being declared). Here's the code I am using: #include <stdlib.h> #include <stdio.h> #include "Adafruit_FONA.h" #define FONA_RX 4 #define FONA_TX 3 #define FONA_RST
  9. Hello , I'm new to this field of microcontroller and i need you quick help with a new project of mine. I'm using MSP430F5131. I will explain a little about the project : My main goal is to generate a 1 pulse per second using a 12.8MHz external oscillator. I already have a printed PCB for that project which means i got to understand what the previous designer had done and implement it into my CCS program in order to program my micro controller. i am still new to this whole microcontroller world and im eager to know more , although im short in time. I have attached an electrical wiring of t
  10. Hi! I would like to interface a combined GPS + GSM module to an MSP-EXP430FR5969 using Energia. The aim is at the press of a button/signal, an SMS is sent with the GPS lat/long coordinates at the time of the press. I am planning to use this module (https://tronixlabs.com.au/arduino/shields/3g-shield/adafruit-fona-3g-cellular-breakout-900-and-2100-mhz-for-optus-vodafone-australia/) to connect it all up. I've seen a lot of Arduino examples on this (e.g. using tinyGPS and softwareSerial) but I'm not sure if this same code will work on the MSP430. Will it? How can I go about chang
  11. After making the wearable MSP430 for Halloween this year I was requested to make more for a children's dance group. I have a question, but first some background. This is the latest version: Everything works fine. I use an adapter with pogo pins to program it as shown in the photo. There are three LEDs on the PCB, a push button switch for the user, and more accessible pins than the previous version. Parts are TSSOP and 0805 SMD. Snap fasteners and stainless thread can be used to connect it to LEDs on the costume. A CR2032 coin cell is used to power it (coin cell holder is on the backsi
  12. I'm new to the whole launchpad thing. I have an msp430 I've looked at everything I can to try and get help but I just can't seem to figure out how to get a 2 axis joysticks values and put them into the computer. I want to make a custom controller with my launchpad.
  13. Hi, I am trying to make a UART connection with a device from serial1 in MSP432. It isn't working as i cannot see anything printing on my serial monitor (I am trying to print the data stored in global variables using serial/USB). Wherein the same code works fine on MSP430 or TM4C1294 devices. I have double checked my wiring connections.. P3.2, P3.3 for RX, TX. Can anyone here help me resolve this issue or point out where im going wrong.. Please find the code below //----------------------------------------------------------------------------- // Microchip MCP39F501 Power Monitor
  14. Good morning, I'm using the latest Energia 18 build with Windows 10. I'm plugged into an MSP430 Launchpad with an MSP430G2553 chip on the board. The following code hangs on the Wire.endTransmission() statement.. Can somebody throw me a bone here and tell me how to fix this? int findAddress(int fromAddress, int toAddress) { int address = 0; for (int a = fromAddress; a < toAddress; a++) { Serial.print(a); Serial.print(" - beginTransmission.. "); Wire.beginTransmission(a); // delay(3); // Wire.write(1); Serial.print(" e
  15. In my project, I use a few basic macros for GPIO. The goal is, that I can easily redefine pin assignment in a central location without compromising performance or code size. The macros (gpiomacros.h): // MSP430 gpio macros #define GPIO_SEL(port) P ## port ## SEL #define GPIO_DIR(port) P ## port ## DIR #define GPIO_OUT(port) P ## port ## OUT #define GPIO_IN(port) P ## port ## IN #define GPIO_IS_INPUT(port,pin) { GPIO_SEL(port) &= ~(pin); GPIO_DIR(port) &= ~(pin); } #define GPIO_IS_OUTPUT(port,pin) { GPIO_SEL(port) &= ~(pin); GPIO_DIR(port) |= (pin); } #define GPIO_IS_PERIPHER
  16. Good morning. I've been using the MSP430 launchpad and programming it using Energia 18. Anyway, for the whole time I've been using Energia, it very often have to unplug and plug back in my device in order to send it another build. Have any of you seen this problem before? Sometimes it works without having to unplug the hardware, however, over 50% of the time, I have to unplug the LaunchPad in order to upload new code to it from Energia. It seems to get hung while attempting the upload. So, to overcome this, I unplug the Launchpad, click the Upload button again, usually get an

  18. I am just getting started on my development using a custom PCB and may pin out on my board is a little different then the launchpad pin out so I need to change the H file. pins_energia.h I need to access p8.0 of the MSP430F5529 and of course this pin is not used on the Launchpad so I need to add it to the h file and use it in my code. Actually I cannot find this file in the downloaded energia software. Standard C requires h files to be declared or #included. Why is energia not using an #include statement in the example c file ( ie blink project) ? How can energia properly access
  19. Hello, I'm new to MSP430.(if I make a mistake, pls tell me!) I just bought a MSP430G2553 and I read that it supports BSL via RS232. I have a FT232 usb -> serial lying around. Could anybody give me a schematic on how to connect my G2553 to my FT232? (and also give me the software for it pls!) (I could instead just buy a Launchpad, but I don't have any money right now! ) Thanks alot!
  20. Hello, I have made the program in which i used timer to generate the pulse. but now i don't want to use timer instead i want to use counter. I have to generate the output pulse when my input counter is more than 200. if it is less than 200, don't want to generate the pulse. I am pasting here my code, help me to generate the output pulse when input pulse is more than 200 input is in pin1.0 and output is from pin 2.0, pin 2.1, pin 2.2. I am using msp430g2553 launchpad #include "msp430G2553.h" #include "stdint.h" volatile uint16_t down_counter; // Variab
  21. Hello, I am making my program using msp430g2553 launch pad. In this i have taken input from P2.4 and i want my output from P2.0, P2.1 and P2.2. In this program i have to generate the pulse of 500ms from input. and my output will be three low pulses from the three pins. Meaning whenever i connect my oscilloscope probe to 2.4 i can see the pulse. But the program i made it didn't work. when i connect to the oscilloscope it is showing nothing. when my input pulse is high i will get the three low pulses output. here is my code, please check it and tell me what is wrong in the code? since it do
  22. For the AT commands from energia's serial monitor it appears as some characters missing!!! Any solutions? Below is my output: AT+CREG? +CREG: 0,1 OK AT+CREG=? +CREG: (0-2) O AT+CFUN=? +CFUN: (0,1,4),(-) K
  23. Hello everyone; As you can see bitshifting a byte 16 bits and storing in a long doesn't seem to work, while shifting storing and shifting again works perfectly. Is this behaviour normal? Using energia 0101e0017 on win7 with msp430g2553 launchpad. Also i'm not 100% sure but i think bitshifting 16 bits worked fine on a tm4c123gxl launchpad because i ran into this while converting a code that was written for tm4c to msp.
  24. I have had a package of those 4x6 cm pcb boards with 0.1" spacing for a while and realized this evening that I was about to run out. They are a good and useful size. Wondering where they all went I rummaged around and found these and there are more scattered about in various enclosed projects. I am in the habit of soldering one up if it is on the breadboard and I think there is a fair chance I might use it again. I like to do this even when I am going to have PCBs fabricated. From top left and going clockwise they are a RFID BoosterPack reader, a Nokia 5110 BoosterPack, an INA125P
  25. Hi I'm just getting started in working with MSP430 with MPU6050. Is Jeff Rowberg's library the go-to library for interfacing with the MPU6050? Ideally, I'd like to use DMP, but that the i2cdevlib library doesn't seem to have that feature. Does anyone know a good way to work with the MPU6050 (preferably DMP) on MSP430? Any thought appreciated. Thanks
