BOOSTXL-DRV8301: LAUNCHPADXL-F28379D Compatibility

Part Number: BOOSTXL-DRV8301
Other Parts Discussed in Thread: DRV8301, , LAUNCHXL-F28379D

Hello everyone.

I tried to check if BoosterPack DRV8301 is compatible with Launchpad F28379D. I was sure, that it is. But BoosterChecker told me, they are not. The problem was in BoosterPavk Pin #29 and Launchpad Pin #69, as shown on the picture. BoosterPack sends Phase C current feedback, and the launchdap pin is "CMPIN". But ASAF, Compare function is muxed with ADC. So the Pin #69 of the launchpad can be used as ADC input. The launchpad schema is a little strange with names: ADCINA4 pin of the MCU is named as "Analog Out". The picture is shown.

What should I do? I still think, that there's some mistake or name mismatch. I don't believe, that this launchpad for motorcontrol purposes is not comatible with motorcontrol boosterpack.

    Hi Disona,

    The C2000 experts have been contacted to comment on the difference between the two launchpads.

    The BOOSTXL-DRV8301 was intended to be used with the www.ti.com/.../LAUNCHXL-F28027F

    Hi there Disona,

    The CMPIN1P pin is ADCINA2. please refer to the board schematic and device datasheet. This Boosterpack is compatible, though I am not sure if there is example software for this specific combination. That being said, the differences will be minor between the F2802x and F28379D.

    I will file a ticket to get the BoosterPack Checker updated.

    Regards,
    Mark

    Thank you, Mark

    I've figured out these devices are compatible, I've already spinned a motor. But unfortunately, ADCREFHI is set to 3V at LAUNCHXL-F28379D, and the BoosterPack has it's scale up to 3.3V, so there are some problems. I have Launchpad of Rev 1.1, but i can see, that Rev 2 has also reference at the level of 3V =(
