LAUNCHXL-F28379D: LAUNCHXL-F28379D and BOOSTXL-C2KLED compatibility

Carlo

Part Number: LAUNCHXL-F28379D
Other Parts Discussed in Thread: BOOSTXL-C2KLED, CONTROLSUITE, BOOSTXL-BUCKCONV, C2000WARE

Hi team,

Good day.

Are the LAUNCHXL-F28379D and BOOSTXL-C2KLED  compatible?  What is the connection between the two boards?

Do we also have a voltage sensor board compatible with LAUNCHXL-F28379D?

Regards,
Carlo

    Carlo,

    We are trying trying to located SME, please expect response by tomorrow or Monday.

    Hi Carlo,

    From a hardware perspective:

    These boards can connect together without creating contention, but the F28379D LaunchPad would not be able to control that LED boosterpack without making some modifications.  Specifically, it looks like IRED, IBLUE, VGREEN, VRED, and VDCIN would need to get connected to other pins on the LaunchPad header in order to enable software to control it.  It seems like it would be feasible to do this via jumper wires at the expense of some robustness.


    From a software perspective:

    We don't have a software example connecting this LaunchPad & BoosterPack.  So customer would need to create it themselves.


    Because of the above, this would likely be a pretty tough user experience.  So I would have two suggestions for a different path:

    1. This BoosterPack was designed around the F28027 LaunchPad.  Its hardware can connect up directly & there is a software example within controlSUITE for this combination.
    2. The BOOSTXL-BUCKCONV controls a buck stage instead of a boost stage as is done in the LED BoosterPack.  However, the software framework & concept are similar.  This buck design is more up to date & easier to use.  The documentation for it is written for a customer using the F280049C LaunchPad, which is similar to the F2837x & C2000's newer device families.  This would be a great starting point, and is one of the main system boards we suggest for new customers to learn on.

    Can you give some more information on what you mean by a voltage sensor board?


    Thank you,

    Hi Brett,


    Thank you so much for a very detailed response. Our customer is looking for the name of the pins of the  BOOSTXL-C2KLED   to make the necessary connections with LAUNCHXL-F28379D, do we have a document indicating these pins?


    Regarding the voltage sensor board, our customer needs an EVM which contains 3 voltage sensors, these sensors will measure circuit voltage and the signal bandwidth to be measured is 500kHz. Do we have this type of device?


    Regards,
    Carlo

    Hi Carlo,

    You can find schematics for both these boards within C2000Ware (or the older controlSUITE).  Once downloaded, these would be located within C2000Ware at:
    \ti\c2000\C2000Ware_2_00_00_03\boards\LaunchPads\

    Below is an image of the signals that would need to be rerouted to an unused LaunchPad pin which has an ADC input.

    I'm not aware of a BoosterPack exactly like this.  However, the implementation wouldn't be too complicated.

    • If the voltage source is within range of 0-3.3V & has low output impedance, it can go directly into a C2000 ADC input pin.
    • If not, the signal's amplitude may need to get reduced by a voltage divider & then buffered by an opamp in a voltage follower configuration.
    • Note that the F2837x has 4 ADC each capable of working at 1.1MSPS.  So multiple analog signals/voltages could be sampled simultaneously.


    Hopefully this helps!


    Thank you,
    Brett
