  1. Hello from Berne, Switzerland. I am working on Visible Light Communication at Lovefield Wireless, Switzerland, and like the vast amount of solutions already available for the MSP430 family. I am planning to use parts of my projects for University teaching (open source) and parts for commercial projects.
  2. 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
  3. I have the CC2650 plug-in module and I am trying understand how to use the BLE library in Energia. I installed the BLE library. The reference page, http://energia.nu/reference/ble/ says that two demo programs are included in Engergia: SerialOverBLE and BLEInputOutput but where exactly are these programs? I would like to download them into Energia and learn about BLE serial communication. -Bob
  4. Hello all! I am currently working on a project that uses two NRF24L01 modules to communicate between two MSP430G2553 chips. The goal is to send a 14 character string of numbers and letters between the two devices. I have been trying to get code working with Code Composer Studio for a few weeks now, but have had no success at all. I found several posts on this forum from others who have tried similar things and this post in particular, http://forum.43oh.com/topic/2050-nrf24l01-registerscommands-and-functionswork-in-progress/page-2 with a link to a library created by Spirilis, however I
  5. Hello, I want to make a wireless thermometer using two microcontrollers. How do I write the code in Energia to transmit and receive a variable using a 433 Mhz RF module? Transmitter Setup: I have a TM4C123G connected to a RF transmitter using TX(3) pin 34 on the MCU. The TM4C123G is also connected to a LM34DZ Temp sensor. I need help to modify this working code to send the temperature variable using tx(3) pin 34 /*TM4C123G*/ //initializes/defines the output pin of the LM34 temperature sensor int outputpin= A11; // (pin # 2), use A11 analog input //---------------
  6. Hello! This is my first post, I'm a new board member. I have searched the forum for examples relating to my question and haven't found anything that's quite like what I'm looking for, so here goes. I am trying to build a system where a switch can be flipped on one board and it lights up an LED on another board. I have used the WirelessControl example program to verify that my boards are working and they do. I would like to just modify WirelessControl because it's a relatively simple program and it's already doing what I need the boards to do. The WirelessControl example program requ
  7. Hello, I think it is a good place to post information about this library I prepared. It is a very simple NRF24L01 library. The library is in C and can be used for any hardware platform with very minimal change. Please feel free to comment and criticize. I tested this using Stellaris Launchpad. Projects using CCS are available in GIT repo. Blog post: https://unboxnbeyond.wordpress.com/2015/04/03/pdlib_nrf24l01-v1-01-a-portable-nrf24l01-c-library-for-multiple-hardware-platform-integration/ Git repo: https://github.com/pradeepa-s/pdlib_nrf24l01 Thank you!!!
  8. So I recently purchased some "NRF24L01+" boards on eBay. I didn't notice until after the fact that they're chip-on-board and are missing a TON of the components that you typically see on these modules. I found some discussions online about these types of boards - http://www.avrfreaks.net/forum/help-identifying-nrf24l01-compatible-modules. The eBay seller swears that they're genuine NRF24L01+ - but I seriously doubt that - I just need proof. So my question - what's the best way to test these to prove one way or another? I honestly haven't plugged them in - but my first test will probab
  9. Dear colleagues, I'm more than happy to announce the release of panStamp NRG, our new Wireless ISM (868/915 MHz) module based on the CC430F5137 MCU and programmable from the Arduino 1.5 IDE. panStamp NRG is pin, radio and software compatible with our classic AVR modules but entirely relies on a Texas Instruments CC430F5137 MCU instead of our old Atmega + CC1101 approach. As result, we are getting a more robust module providing more features, more speed and consuming less power. Wiki page Commercial website Webstore panStamp NRG can be programmed serially from the Arduino
  10. I want to use nRF24l01 RF wireless modules with MSP 430f247 processor. There is a project done on MSP430G2553 with the same wireless module; https://github.com/spirilis/msprf24/wiki#library-usage I want to use USCIB_0 part for communication interface. I replaced output pins in the program. When I debug the program step by step I have seen no signal at SPI line. Do you have any suggestion?
  11. Hi, I am designing a remote controlled system using an arduino uno board and a msp430 launchpad with the ASK RF module (HT12E and HT12D ICs). I am using the msp430 as the transmitter and the arduino uno for the reciever because of requirements of my application. Being familiar with Arduino, i am trying to use energia to program the msp430 with the VirtualWire library. #include <VirtualWire.h> int button = P2_2; int transmit_pin = P2_1; int a,counter=0; char msg[4]; void setup() { vw_set_tx_pin(transmit_pin); vw_setup(2000); // Bits per sec pinMode(button,INPUT)
  12. can we interface ADC chip directly to our PC..I am targeting for LabVIEW software in PC.I want to design oscilloscope without using any controller hardware...??Also suggest me ADC chip which has wireless UART
  13. I am currently playing with a nifty little module from Anaren called AIR (2pg pdf:http://www.anaren.com/sites/default/files/Part-Datasheets/A1101R09C.pdf), for a low-power embedded project and it works OK; but I was wondering if anyone else had experience with any other like type modules? My loose requirements are that I would like to reasonably (not pie-in-the-sky) hit 1/4 - 1/2 mile distances at slow speeds (9600 baud is fine). I would like to use an omni antenna (so no high directional antennas), would prefer the module to have pre-FCC approval, and would like the modules to be less than $
  14. I've built a wireless temperature monitor with the following features: Very low-power (7uA) sleep mode Dual 1-wire dallas temperature sensor inputs, to measure two temperature sensors at the same time. A 2-line LCD display that displays the current measurement for 15 seconds when a button is pushed. 2xAA battery supply, with charge pump to power the LCD, temperature sensors and 433Mhz wireless module. Uses VirtualWire to transmit the data to an MSP430-powered receiver module. This is all currently sitting outside, and the indoor rx unit is uploading the measured temperatures as well as the
  15. I have been working on a few different projects that could be described as wireless sensor nodes. Just to get something working I decided to hack a retail router to give my MSP430 wireless capabilities. The first step was to install OpenWRT Linux onto the router to make it configurable. After that I mounted the file system onto a flash drive that was using the built in USB port on the router. From there I broke out the convenient 3.3v serial connection and hooked it up to my MSP430. Currently I am working on a full write up that will include compiling OpenWRT from source and detailed step by

    The ENC28J60 Booster Pack thread has got several posts that venture into wireless networking and internet of things. I thought it might make sense to bring these discussion to their own thread. The topic title might not be spot on, but it's fuzzy enough to cover almost everything :-) Please add your ideas and comments to this thread (maybe even re-post ideas from the ECN28J60 Booster Pack thread). I am currently playing around with a couple of CC2500 modules, which I am going to use for a small sensor network at home. Sensors could be anything such as temperature, humidity and motion s
