    canid reacted to gwdeveloper in SimpiciTI Tutorial for CC2500   
    This tutorial is meant to provide simple instruction to prepare a SimpliciTI wireless project using the TI Launchpad and CC2500 radio. Currently, CCSv5.1 will compile this program but have a few syntax errors. They can be ignored for now. CCSv4 will compile with no issues.

    Please feel free to critique and ask questions. It helps to make us all better.

    Part 1 of 2

    Hardware Needed:
    Launchpad with MSP430G2553
    CC2500 Radio (several variants available; MDFLY CC2500 breakout or ez430-RF2500t)
    (will insert an image of various hardware versions from TI to DIY)

    Software Needed:
    TI's CCS v5.1 http://processors.wi...hp/Download_CCS
    SimpliciTI 1.1.1 for CCS http://www.ti.com/tool/simpliciti
    LP_G2553.zip (launchpad BSP for simpliciTI)
    2274_SimpliciTI_Toggle.zip (only needed for RF2500T used as slave; it will disable the cpu and set up peripherals to toggle leds) 2274_SimpliciTI_Toggle.zip

    Step 1: Install Softwares.

    - Install CCS v5 OR V6 for the MSP430 (if you don't already use CCS)
    - Install SimpliciTI 1.1.1 (make note of the install directory; we'll use C:\Texas Instruments\SimpliciTI-CCS-1.1.1)
    - unzip LP_G2553.zip bsp files to C:\Texas Instruments\SimpliciTI-CCS-1.1.1\Components\bsp\boards
    - modified vlo_rand library for easy address assignment will be unzipped later
    - for RF2500T, unzip 2274_SimpliciTI_Toggle.zip to your current CCS workspace
    --- this project will need to be imported to CCS via Project -> Import Existing CCS Project

    Step 2: Create CCS Project

    -File -> New CCS Project
    -Give project name. Select MSP430 Family and MSP430G2553 as variant. Connection should be left to default and Empty Project selected for template.

    Step 4: Create project file structure

    -Now you will need to open the SimpliciTI\components folder.
    --- for eg; C:\Texas Instruments\SimpliciTI-CCS-1.1.1\Components
    (after the following actions, select "Link To" for the copy action)
    -- drag 3 files from ..\bsp to the bsp project folder
    -- drag 3 files from ..\mrfi to the mrfi project folder
    -- drag all files from ..\Simpliciti\nwk to nwk project folder
    -- drag all files from ..\Simpliciti\nwk_applications folder to nwk applications project folder
    -We'll borrow the nwk .dat files from the EZ430RF project
    --drag smpl_nwk_config.dat from \SimpliciTI-CCS-1.1.1\Projects\Examples\eZ430RF\Simple_Peer_to_Peer\CCS\Configuration to the configuration project folder.
    --drag smpl_config.dat from \SimpliciTI-CCS-1.1.1\Projects\Examples\eZ430RF\Simple_Peer_to_Peer\CCS\Configuration\End_Device to the end device project folder.

    For anybody who missed my comment here i thought i would post it here.
     
    I was able to replace my borked LP and am able to offer one to the next person who needs one but can not afford it. $4.30 isn't a lot of money to most of us, but sometimes things are rough.

    I have not been able to fix the borken one. I wanted to update to let everybody know that I was able to replace my Launchpad. I bought two just in case.
     
    In the spirit of community that this forum has shown me, and because it's the Holiday season, I would offer to help out. If somebody else here knows what it's like not to be able to come up with $5 for equipment and needs a launchpad, please let me know. Limited to places that TI will ship.

    Hello,
     
    My friend has faced the same problem. It was after me trying to get him to embedded design, that he bough his first MSP430 Launch Pad kit. But then it was not working in the same way as you said.
    I suggested a simple route:

    1. Disconnect the LaunchPad board from the PC
    2. Remove the Socketed MCU
    3. Use capacious amounts of IP(Isopropyle Alcohol) to clean the LaunchPad on both sides. (Take care for ESD damage)
    4. Let is dry for some time till all the IP on the board has vaporized
    5. Now remove the All Programming jumpers on J3
    6. Connect the Board to PC
    a. Check it is being detected
    ->if so then one level of your problem is solved
    b. if not detected or as you said its getting heated up
    ->Only option is to buy a new board
    7. If it was working then check for the voltage at the VCCpin of J3 and ground.

    -> If thats 3.0 - 3.29V then everything is alright.
    Place back the MSP430 in the socket and the jumpers on J3
    You can get back to business and have a happy time with MSP430.
     
    Hope that this helps.

    Yes. Should not be a problem at all. Unless it is an entirely different issue.
     
     
    Was this 3.3V or 5V? You cannot supply the target side 5v as it goes directly to the MSP430 chip which can handle a max of 3.6V. I'm unsure what is the voltage requirement of the USB chip though.
     
    Where around are you resided?
