  1. This is a fun project that was created for my embedded systems class at John Brown University that allows you to create your own quiz wizard similar to the jeopardy game show system. The main portion of this code is run on an MSP430F5529 launchpad, and nRF24L01 transceiver modules were used to obtain the wireless functionality. It makes use of the Enrf24.h library to operate the transceiver modules, and the user interface is output to the serial monitor of the energia IDE. Four buttons wired into the MSP430F5529 then allow the user to interact with the system. The wireless module was created
  2. Hi everyone. I'm new to this forum and new to TI mcu. Planing to get a launchpad with msp430g2553 I have experience with atmegas, and arduino ide. I have a project to have some sensors around with batteries and a central receiver to publish to internet, the will comunicate vía nrf24l01 which is a SPI device and in the array of sensors some of them are I2C. As I see the description I2C and SPI share the pin in Msp430G2, so my question: is possible to use both in the same project in a reliable way? I did this project with atmega328 and arduino ide but I read the msp4
  3. I need help getting MSP430F5529LP to receive signals with nrf24l01 from MSP4302553. MSP4302553 Sends signal to another MSP4302553 with no problem. But cant get MSP430F5529LP to receive anything. I don't know if it is because of two SPI communications on the MSP430F5529LP or because the clock rate is different or something else. Please Help!

  4. Hi, Im trying to use the NRF24l01 with the MSP430 and i'm using the enrf24 library with my g2553. how do i set the transciever to open pipe 0 with address 0? I have an arduino receiver listening to pipe 0 and expecting data from a device with address 00001 on pipe 0.

  7. Hello I have been trying to implement multiceiver on nrf24l01 and msp430g2553. Basically I am trying to use different pipes for the same rf channel. The library and the example code I am using is the spirilis one, one of the most common. The problem is that I can only work with the default pipe 0 given in the code when ever I try to use the other pipes I can't get anything. I read the datasheet about the multiceiver part, I guess I understand both the code and the working mechanism but I still can't use the different pipes. Any help would be appreciated. What I do is that; at first by usin
  8. 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
  9. 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
  10. This is the first PCB that I have designed and sent off to be manufactured. Yesterday I received the boards, soldered them up, and they work! This write-up outlines the process I used in the hope that it will be useful to other hobbyists and builders. There are links at the end which provide additional detail. Selecting a Project The project consists of a small board with a MSP430G2553 microcontroller and an nRF24L01 radio. I started with a radio attached with jumpers to a LaunchPad quite some time back and then built one on a proto-board. The photograph below shows a G2553 with r
  11. Hi good day ... I'm doing a project that consists of a network of RF sensors that communicate to a station connected to the Ethernet network, the target station that read the sensors and update the variables shown in the IP address configured. I have connected the module NRF24L01 SPI port 2. I am using Enrf24 library. I have the enc28j60 SPI3 module connected to the port. I am using the library UIPEthernet, configure the module to use port 3 Enc28J60Network modifying the file that is included in the same library. I have the following problem: -The NRF24L01 module works well alone. (Alt
  12. I've got a bunch of sensors in my house uploading data to my phant repository - but I decided to start looking into placing sensors outside as well. I purchased some $2 solar sensors from Target (Apparently they're frequently available from the dollar store as well - I'll check into that) in the hopes that I could use them to power an MSP430. The ones I purchased only provide ~1.2v of power since they're single battery. They're 200maH as well, but I think that will likely be plenty for my uses. Since one wouldn't do it - I used two in series. At full power - that should be around 2
  13. 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.

  14. I have played around with spirillis msp430 nrf24l01 libraries and written some simple applications using them, which is great. But now I am looking to set up a node network for sensors and actuators. I would like to have something a layer above the spirillis nrf24l01 libraries that could act as a way to either mesh network or star network the nodes. Maybe I am not searching the right things, but the best thing I have found so far is something from MySensors that seems to be Arduino only. What I like about the mysensors is that it looks to handle the networking of the nodes for you. Ar
  15. So this project is in the works - but I haven't been posting much lately and I wanted to start up a thread on progress. Here's the basic idea. I have had a BeagleBone Black for quite a while. I've mostly been using it to run my 3D printer. However, I updated to Debian which seems much more stable than Angstrom. I've also hooked it up to my TV and downloaded an NES emulator. It's pretty cool, but it would be much nicer to have a real working NES controller. I just happen to have purchased some knock-off NES controllers from eBay a while back. I also have several NRF24L01+ radios on h
  16. Good day, I want to connect my Stellaris launchpad and the MSP430 2553 using NRF24L01 transceivers. I found following energia libraries, For MSP430 http://forum.43oh.com/topic/3237-energia-library-nordic-nrf24l01-library/ For Stelaris launchpad http://forum.stellarisiti.com/topic/464-energia-library-stellarpad-mirf-nrf24l01-library/ After that I connected the pins of the modules like below, MSP430 CE >> P2.0 CSN >> P2.1 SCK >> P1.5 MOSI >> P1.7 MISO >> P1.6 Stellaris launchpad CE >> PA6 CSN >> PA7 SCK
  17. Good day for all, I want to know if exist the nrf24l01 library on Mpy or if the SPI library is available. Thanks!
  18. In this day and age, we should not need to use any keys or buttons. I have done away with the key remote in my car using this simple setup. I came to the same conclusion as this gentlemen in using the apple nike+ sensor to provide a proximity sensor to the car. https://www.sparkfun.com/tutorials/135 His code lacks a couple things that I was looking for. 1) decoding of the apple serial protocol so that i can use any NRF module 2) detection of when to stop strobing the remote (when the key is inserted) 3) ability to open the trunk and since I can detect when the key is inserted,
  19. Hi, I've finally found my "cahones" and decided to become a doer, and hopefully more active on the forum. I've been working on his for more than a year on my free time and have learned a lot. However, nothing real have come out of this project until recently. With the recent release of energia library for nRF24L01P by spirillis, I decided to restart working on it. Anyway. I'll post what I've done so far and move along with the suggestions. I'm a noob, so I've gone the noob way: Breadboarded first using what I had in my noob bin (msp430g2553 , nRF24l01P, ds18b20, thermistor, 7805, lm35
