LaunchPad EK-TM4C123GXL

Other Parts Discussed in Thread: EK-TM4C123GXL, TRF7970A

I plan to buy the EK-TM4C123GXL LaunchPad with its NFC and Bluetooth BoosterPacks.

I would like to confirm its hardware/software compatibility with the following two BoosterPacks:

(1) TRF7970A NFC BoosterPack

(2) The BluePack - HC05/HC06 Bluetooth BoosterPack Breakout PCB (from 43oh) + HC06 RF Wireless Bluetooth Transceiver Slave Module (from 43oh)

Please help.

  • Hello Rajmohan,

    The compatibility of the booster pack to the LaunchPad for TM4C123 is given at the following web link

    http://www.ti.com/ww/en/launchpad/boosterpacks.html

    Use the "Filter LaunchPads" option to select TIVA-C and see which booster pack will be applicable. if it is not there then HW interposer and SW would need to be built

    Regards

  • Hello Amit,

    Thanks for the quick reply.

    The NFC and BT BoosterPacks are listed only when I filter with "MSP430" as LauchPad type.

    But, the TM4C123G LaunchPad User Guide states that, "Tiva C Series BoosterPacks and MSP430 BoosterPacks expand the available peripherals and potential applications of the Tiva C Series LaunchPad."

    Does it mean, these BoosterPacks are compatible with Tiva C Series LaunchPad also? I'm confused.

    Regards,

    Rajmohan

  • Hello Rajmohan

    In which case the correct strategy would be to check the pin outs of the booster pack and launchpad. This way you will get to understand more than me telling a simple "yes/no"

  • Hi,

       The boosterpacks that are not pin compatible with Tiva Launchpad, you would need to re-wire by means of protoboard or similar to make it compatible with Tiva Launchpad.

  • TivaWare 2.1 has examples for the TRF7970A so it works.  They (TI) do build and test the binaries for each build on the given board(s).

    Look for the ek-tm4c123gxl-boost-dlptrf7970abp folder in examples\boards\

     

    I am not familiar with the BluePack.  I have been using the KooTek BT2S Bluetooth to serial adapter (originally made for Arduino) lately with good success on LaunchPad. http://www.amazon.com/Kootek%C2%AE-Bluetooth-Serial-Module-Arduino/dp/B00DQ4A7O6 I believe it will work off of the serial boosterpack pins and not interfere with the 7970 operation nor the debug serial port.

    That's good input - thank you.

    Might not your group's creation of a, "proper, direct/exact, plug-in" such booster-board create a market opportunity?  Having something ready made - tested/verified - and both comfortable & convenient for the end user - usually results in Sales success. 

  • We'll consider it.  I have not yet determined if the boosterpack 3rd party market is sufficient to warrant our entry.  Chasing a few hundred units here and there does not make compelling arguments to the business managers.

     

    This may be a good entry point as it would be useful internally regardless of the external market.  We have to date been wiring up the four connections manually with jumper wires.  A total of under 10 units so far.

     

    To the community: Would an out of the box ready to work on Launchpad BoosterPack based on the Kootek or similar Bluetooth to serial module be worth $29?  Would you rather have a more complicated full feature Bluetooth or something simple that just works like the serial ports we all know and love?

     

     

  • I found the examples for TRF7970A in TivaWare. Thank you very much.

    However, I couldn't find examples for any Bluetooth module. Does it mean that the LaunchPad not supports any BT module?

    Where can I find the datasheet/software stack for the KooTek BT2S Bluetooth to serial adapter?

    Please help.

  • The best information resource on the kootek I have found is https://www.virtuabotix.com/virtuabotix-bt2s-slave-configuration-pinout/ Though on review I am wondering if the kootek is a knockoff of this device. In which case I suggest buying from virtualbotix since they actually document and appear to offer some support.

    Regardless the kootek responds to the AT commands at this link.  Aside from that it just hooks up to a 3.3V or 5v digital UART signal directly off of Launchpad with out a converter. It basically just works out of the box. All the stack is on the module.

    On the embedded side it just looks like a serial port.  On the Bluetooth master side it does all the right Bluetooth stuff and enumerates as a Bluetooth serial port profile (SPP).
