  1. Hello everyone, I have a project which requires GPS + Wi-fi capability and fastest clock speed mcu possible. For GPS capability I came across CC4000 which seems alright, but I'm confused on which launchpad board to select that has Wifi capability also. I have worked on Arduino but new to TI's Launchpad. Please suggest me for what should I buy. link for the CC4000 gps module kit : http://www.ti.com/tool/cc4000gpsem?keyMatch=gps&tisearch=Search-EN-Everything#descriptionArea
  2. Hello again, I am trying to connect up 2 MSP430FR4133 using the slave_sender and Master_reader examples in the energia given examples. There is no information about which pins to use but RXD and TXD are the only pins outputting on the scope so i have tried these pins. I have also tried connecting up the pins that say they are for SPI on the pin layout to no success. Any help would be greatly appreciated. Kind regards, Chris
  3. After joining this forum over 3 years ago I thought it overdue that I say hello and contribute something that I hope you will find useful. Attached is a picture of simple booster packs that I make. But are they really a "booster pack"? Hmmm. Debatable! They are cheap and easy to make and I have made 5 of them. I use them all the time because the whole of each project, including the MSP430, is attached to the booster pack. This means I can switch between projects without re-wiring, I can change the model of MSP430 in seconds and I only need one Launchpad. You can see from the pic
  4. Hey everyone, I am trying to reduce the power consumption of my msp430FR4133 by reducing the clock speed from 8MHZ. I am using the http://annem.github.io/ADXL362/ example code as a base which sets the default clock speed to 8MHZ. I have read that the Wiring.c file defines the clock speed but I cannot find where F_CPU is defined. Any help would be greatly appreciated thanks.
  5. Hi, Wondering if anyone can confirm if the MSP430 source code listed in this article can indeed be used with Energia (IDE and library) ? Idea being mixing Energia library for AnalogRead and SPI data sending capability. Also, I'd like to use the LP with MSP430G2553 to perform ADC for 6-8 channels, and convey the same to RaspberryPi over SPI using this mechanism. Given the very limited RAM on MSP430G2553, what is the likelihood of being able to squeeze in such functionality along with the SPI communication ? Pointers to any existing projects at achieving similar goals, would be hi
  6. Hi, These after read this thread about how to use temperature calibration data, I tried to use TLV register to obtain the "real" voltage reference value and increase the ADC conversion by compensating the gain and offset. The test was performed in a Launchpad EXP430FR6989, but can be applied to other launchpads compatible with MSP430Ware driverlib. The increase in the accuracy is very interesting. in the table (sorry by the comma instead of point, brazilian notation).

  7. I'm new to MSP430 and I'm trying to do a frequency/period measurement. I've read about timers and get the main concepts though I'm still learning. To get an idea of how they work, I'm using this code. It outputs a PWM on one pin which I connect to another pin for capturing period: http://coecsl.ece.illinois.edu/ge423/datasheets/MSP430Ref_Guides/Cexamples/MSP430G2xx3 Code Examples/C/msp430g2xx3_ta_21.c After making some modifications (removing unneeded code to light led and adding calculations for frequency) it works with the original pins. However, I want to change which input pin will t
  8. I have the chip number MSP430FR6989 and I want to use it to read 10 analog DC signals then do some processing (multiply them by certain factors) after that I want to convert them back to analog using PWM and RC filter, my issue is in the second part , how to use timers( set period , duty cycles) of the MSP430 to produce PWMs from the analog inputs. This is the code: #include <msp430.h> #define ACLK 0x0100 // Timer ACLK source #define UP 0x0010 // Timer UP mode #define ENABLE_PINS 0xFFFE // Required to use inputs and outputs #define ENABLE_PINS 0xFFFE // Enables
  9. Hi, I am using MSP430 launchpad with G2553 controller. When I am using sleep(5000), and varying the voltage on the controller from 3v to 4v the timing is varying based on the voltage, but the timing in not changing when I am using delay(5000) when I am varying voltage. Any help will be appreciated. Regards,

  11. 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
  12. Is msp430fr5994 launchpad supported by any realese of energia ? I searched in boards section and couldn't find. Is there any patches to make it work ? Or it's not supported ?
  13. I know I haven't finished off my desk clock project just yet, But I've been requested to design a new GPS logging device for my sisters Beagle Club, The basic idea is that a sent is placed with a guy that forms a path, the GPS logger is taken along also. They then attach the device to a beagle (using some kind of vest, I think). And let them follow the scent. Post event they extract the GPS data from the logger and overlay both tracks in google earth. They have one unit that has been working well for them, developed by a previous club member. It consists of off the shelf c
  14. Hello guys i have a project at my school were i need to make an energy metter with a msp430f5529 and a hardware part i did all the code myself and the hardware part (current metters,voltage divider etc), (i know is rudimental and ineffective) , the code and the montage works well and does everything i need it to do.Now my professor asked me to save "energie1" and "energie2" so when my microcontroler runs out of battery this 2 variables are saved , i read a lot of threds but i can't figure it out.Here is the code if it helps ( i can provide you with hardware montage if needed). #include
  15. Dear Developers, I want to send data from MSP430F5529 to my Arduino Nano through UART connection. But somehow it is not working filne. I have used voltage devider circuit to convert Arduino's 5V to MSP's 3.3V. Connection Arduino's RX -> MSP's TX Arduino's TX -> MSP's RX Ground of Both -> ground of voltage devicer. Code of Arduino : const int chipSelect = 10; String inByte = " "; void setup() { // initialize both serial ports: Serial.begin(9600); } void loop() { if(Serial.available()) { char b = Serial.read(); Serial.println(b); }
  16. 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
  17. Dear Engineers, Please help me send data to Arduino from my MSP430F5529 using SPI interface. I want to use SPI iterface because in future I want to use the modified code for Attiny13A instead of the Arduino Leonardo. Details are given below. Thank you for your support.

  19. 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

  22. I've been using Energia successfully (on Mac) with several programs and the MSP430FR5969 and MSP430F5529 LaunchPad boards for a couple of weeks now. Today I acquired an MSP432P401R LaunchPad and so installed the "Energia MSP432 boards by Energia" package from Boards Manager, version 3.8.0. After that all my MSP430 sources compile with large numbers of errors, and I can't get them to work. Is there some way I can undo the effect of installing the MSP432 update and get back to how things were before? I've tried downloading a fresh copy of the Energia application, and deleting the
  23. Is there any documentation about how to view the assembler code for the object file that the Energia IDE produces? On the Arduino you can do it by copying a line from the verbose compiler output, editing it, and then running it from the command prompt: http://rcarduino.blogspot.co.uk/2012/09/how-to-view-arduino-assembly.html Thank you, David
  24. Hello! In my own automation system I have to encrypt data transferred between sensor and main controller (data transfers via twisted pair). For this reason, I need a special devices - encryption gateways (one gateaway installs on sensor-side, another on controller-side). These gateways realize following algorithm: Sensor-side: Receive some data from sensor (via discrete input); Encrypt data using AES; Transfer encrypted data to controller-side gateway. Controller-side: Receive encrypted data from sensor-side gateway; Decrypt data; Transfer
