DRV5055-5057EVM: out put the volts data in GUI

Part Number: DRV5055-5057EVM
Other Parts Discussed in Thread: DRV5056, DRV5055, DRV5057, HALL-ADAPTER-EVM

Hi team,

Our customer want to know do we have software (like GUI) in laptop for DRV5055-5056EVM to output and display volts curve/data?

    Hi Kailun,

    Thanks for posting to the sensors forum.

    We do not have a GUI for the DRV5055-5057EVM as it is a plug-and-play board that only requires a USB power connection, and the values are displayed on the onboard LCD.

    The onboard test points TP2-TP13 are intended for users to be able to easily access device pins. Perhaps the customer can use an oscilloscope or other instrument to gather the data via those test points.

    Best regards,

    Jesse

    Thank you Jesse, 

    One more question, our customer feedback that when they remove other unrelated sensor in the EVM and only reserved DRV5056, they found that the EVM can not work normally. Only D13 is lightening, even they press the selected switch.

    I am not sure if it is due to the heat corrupted the DRV5056 or the EVM have to work with all the sensor in board.

    Hi Kailun,

    I have not tested this myself, but I believe the EVM should still work even if some of the DRV505x sensors are removed. I will see if I have an EVM to test this out on.

    Which components were removed specifically, only DRV5055 and DRV5057 sensors, or were there other components removed as well? Do any other LEDs light up other than D13, even when S1 is pressed multiple times?

    The EVM schematics are shown in section 4.1 of the EVM user's guide. Section 3.2 describes the EVM theory of operation and Section 2 also has details on operation.

    Hi Jesse,

    Thanks for your reply. As you can see in the picture, they only left A1 sensor. I have checked with them, there is no other LEDs light up other than D13, even when S1 is pressed multiple times.

    Hi Kailun,

    I had initially assumed the sensors were removed by desoldering, but I now see that the customer cut the EVM board in order to remove the other sensors.

    We do not recommend modifying the EVM board in this way. It is hard to tell if any components were damaged during the cut, or if traces or planes on the board are now damaged or shorted. I recommend the customer evaluate with a new DRV5055-5057EVM, or they could take a look at the HALL-ADAPTER-EVM, which includes a breakout board with a TO-92 footprint. Note that device samples are not included with the HALL-ADAPTER-EVM--they must be acquired separately.
