BOOST-DRV8711: Which launchpad board to use for two BOOST-DRV8711's?

Matt Praeger
Prodigy 20 points
Part Number: BOOST-DRV8711
Other Parts Discussed in Thread: EK-TM4C129EXL, MSP-EXP432E401Y

I am interested in using two of these BOOST-DRV8711 modules to drive some stepper motors.

(Actually the stepper motors are for use in a vacuum so they require high voltage, low current to minimise heating).

I'm completely new to TI development boards but have used Arduino's before.

Please can you tell me if the BOOST-DRV8711's are compatible (i.e. direct plug-in) to this launchpad module: EK-TM4C129EXL?

Is that the best/cheapest board to choose for this (it would be nice to be able to send motor commands over ethernet eventually).

Is software available for download from TI that will get the two stepper motors operating quickly?

Thanks very much,

Matt

    Hi Matt,

    According to the compatibility checker ( dev.ti.com/.../ ) the BOOST-DRV8711 is compatible.

    The board was designed to be used with a MSP-EXP430G2 LaunchPad.

    The code for the MSP-EXP430G2 LaunchPad is available on line.

    Hi Rick,

    Thanks for your reply.

    Yes, I saw that information on the datasheet but the board suggested seems to only have one launchpad port. If possible, I want to use two of the BOOST-DRV8711 modules connected to the same board.

    Is that possible:

    a) From a hardware point of view. If so which boards with two launchpad positions will work?

    b) From a software point of view. I.e. Does the software mentioned in the BOOST-DRV8711 user guide support two modules?

    In the event that the existing software only supports one BOOST-DRV8711 module; could control of two modules by one board be achieved relatively quickly and easily with some basic programming skills?

    We will contact the experts to provide an answer.

    The software was written to support one module. It is possible to modify the code, but may take some time. Also please note the EK-TM4C129EXL is not MSP430 based. Some of the code will have to be adjusted to account for this.

    Hello Matt and Rick,

    As long as the BoosterPack header conventions are followed with the BOOST-DRV8711, then it should be possible at a hardward level to achieve this. However we do not have any collateral for that BoosterPack as part of our TivaWare offerings so from an MCU standpoint the support we would be able to provide as TM4C device experts may be quite limited unless TivaWare APIs are used for this application which would likely be a large code update to the existing examples.

    Another option you may want to consider is the MSP-EXP432E401Y which would offer the dual BoosterPack headers and allow you stay within the MSP portfolio (though with the MSP432 instead of MSP430).
