Part Number: MSP430G2553
Other Parts Discussed in Thread: ENERGIA

Tool/software: TI C/C++ Compiler

Hello.

I am working on a project using MSP-EXP430 G2 Launchpad.

I am in learning phase of MSP-EXP430 G2 Launchpad and its programming and Following are my challenges:

1. I want Radio communication using nRF24l01 with either Two MSP-EXP430 G2 Launchpads or MSP-EXP430 G2 Launchpad and ARDUINO UNO. Can Anyone have worked on this? please provide Documents/ libraries for this communication.

I have gone through a document where MSP-EXP430 G2 Launchpad and TI stallaris board radio communication article is given (given in below link)

unboxnbeyond.wordpress.com/.../

2. I also using CR2032 3v battery to power MSP-EXP430 G2 Launchpad, But this battery get drain within 24 hours due to Power LED, please suggest If I can make this Power lED OFF using CCS or any other options.

3. I also want to communicate an ADC board ADS1274EVM-PDK with MSP-EXP430 G2 Launchpad for better ADC output, Please suggest some articles for this.

Kindly provide some documents and libraries to understand my challenges.

Regards,

Sunil

    Hi Sunil,

    1. Firstly, you should go to the User's guide and software libraries/examples of nRF24l01  for the interface with a host controller. Secondly, you can go to MSP-EXP430 G2 Peripheral Example for how to develop with a MSP430 G2 MCU. Lastly, Please go to Energia library for easy to access software drivers.

    2. You can disconnect the VCC jumper on J3 of MSP-EXP430 G2 Launchpad and power the MCU from the VCC&GND pins on J1&J2 of the board directly.

    3.  Please go to home page of the ADS1274EVM-PDK and you can find the users guide and software on the page. Also you can go to the software page for more guides.

    Please feel free to let me know if you have any further questions.

    hello sir,

    Thanks for your reply.

    1. I had read user guide and software libraries but some error occurs in Varible.h in my program and I cant run the Program. I am using this Launchpad as a receiver.

    2.I already did this, I power this VCC and GND pin with 3v battery externally, I want to remove power LED as it consumes more power from battery and my battery cant even work for 24 hours. I need to Power Off this Power LED using some software Programs or by any means.. kindly provide some solution or suggestion for that.

    The two LEDs that are connected to P1.0 and P1.6 on the MSP-EXP430G2 LaunchPad can be disconnected by removing the jumpers of J5 on the lower left next to S2.

    Hello Sunil,

    Power LED is on emulation Board So if you remove VCC Jumper and giving VCC to MSP430 side VCC pin at J4 / Pin no 1 of J1, it shouldn't consume Power.

    For other GPIO led there is provision of Jumper..

    Yes. That is for LED1 and LED2 but I need to off POWER LED. that is power to indicate board is properly powered which is continuously ON when powrred.

    You can remove all jumpers of J3.

    Thank you. Its working. Removing VCC jumper from J3 and the result id POwer LED is OFF, But I doubt that removing that jumper and providing external battery power, MY board is still get powered?

    If you have an answer please suggest.

    Please suggest best on following
    I also have a ADS1274EVM-PDK That is 24 ADC Board, Can I connect any LCD display and Keyboard with this? If yes then How?

    You only want the microcontroller side of the board powered, right? I think you do not need the emulation side, so disconnecting the Vcc jumper is OK. If you apply power to pin 1 of J1 or to the lower pin of J6, your processor's side of the board will be powered by your battery.

    Yes You are right. Thank you very much for the help.

    Also Please suggest best option on following item.

    Hello Mr. Zhao and Everyone Here,

    I want Radio communication using nRF24l01 module with Two MSP-EXP430 G2 Launchpads: One as a transmitter and other is as a receiver.


    I have gone through a document where MSP-EXP430 G2 Launchpad and TI stallaris board radio communication article is given (given in below link)

    unboxnbeyond.wordpress.com/.../

    Have anyone working on this? please provide Documents/ libraries for this communication.

    Should I communicate both Transmitter and receiver with same PC?

    I have tried some experiments But I cant found success.

    your words are quite helpful to me.

    Thanks in advance
    Sunil
