Evaluation Module floating point and peripherals

Other Parts Discussed in Thread: TMS320C6678, DRV8301, DRV8312, TMS320F2812

Hi,

I was searching for a starting kit. What i would need is a fast processor (I need to perform a lot of floating point multiplications fast as posible),  and peripherals like ADC, Quadrature encoder and PWM. The only evaluation board that i know is the eZdsp F2812. I have read about other evaluation boards with  floating point processors
(like The TMS320C6678 Lite Evaluation Modules (EVM) ), but i havent find anyone which also contains the peripherals that i need (ADC, interface for encoder and PWM). Does something like this exist?

Thank you very much.

    I assume since you are on the motor driver forum you are looking for a kit to control a motor.

    Would say your first step should be looking at that hardware first, then select the processor portion.

    DRV8312-C2-KIT : Up to 50V, 3.5 continuous

    DRV8301-HC-C2-KIT : Up to 60 V, 60A continuous

    TMDSHVMTRPFCKIT: Up to 350V, 4-10A continuous

    All kits ship with F28035 fixed point device on a controlCARD.  The HVMTR kit also ships with F28335 floating point on controlCARD.  The DRV8312 and DRV8301 kits CCS project are dual built to also support F28069 on isolated controlCARD.  The 069 is floating point, though the projects don't specifically take advantage of the FPU.

    ChrisClearman thank you for the answer.

    Mi application is actually parameter identification of a drive.

    I already have the motors and inverter that I will use. What is important  to my application would be the  speed of the  processor to run my identification algorithm but I would also like to have some peripherals (actually just ADC and a encoder interface) to  compare my estimations to some measurements.

    Do you know if there is such a board?

    What do you mean the projects don't specifically take advantage of the FPU?

    Maria,

    We have many inverter boards with a QEP interface, and a digital interface to what we call controlCARDs (Emulation, Serial connection, MCU)

    But since you have your own inverter, If you have low current motors I'd use

    http://www.ti.com/tool/tmdxdock28069

    If you have high current I'd still get above to get started, but then add either an external isolated JTAG pod, or swap in the soon to be released (I hope) ISOLATED version of the F28069 controlCARD (similar to the ISO 28035 version http://www.ti.com/tool/tmdscncd28035iso )

    I forgot to tell that I wont perform the control of the motor . The task of the board will only the identification algorithm, but for this I would require processing speed  to perform a lot of floating point multiplications fast as possible. Im not sure that  60 MHz could be enough. I have read about the eZdsp module for TMS320F2812, it has the pheripherals and the processor is a 150MHz device. Is there  something like this but faster?

    There is a similar breadboard for F28335 if you want 150 MHz and FPU.

    Yes, the F2812 wasnt  FP, this one with FPU will be better. Thank you!
