DRV5055EVM: Interfacing with EVM and getting hall sensor readings with Tivac123gx

Part Number: DRV5055EVM
Other Parts Discussed in Thread: MSP-FET, DRV5055, DRV5057

Hi all,

I have DRV5055EVM and I want to interface with it though any communication protocol with Tivac123gx. Is it possible and if yes, is MSP-FET required to establish this communication?

I want to know the alternatives to access the hall sensor readings in EVM from another TI launchpad.

Thanks in advance

    Hello Maha,

    Thank you for using the TI forum. The DRV5055EVM is not setup to send sensor data digitally via any communication protocol or the MSP-FET. However, there are test points available for each sensor if you would like to read the device analog output directly with your MCU (it is possible that you may need/want a dedicated ADC). The EVM source code is also available on the product webpage if you would like to use it or modify it for your needs. If all you want to do is use the sensor data directly, then you may also be interested in the Hall adapter EVM (http://www.ti.com/tool/hall-adapter-evm) for a more compact board to place the sensors on.

    If you do not want to use an ADC, or do not want an analog output, then you could use the DRV5057, which is essentially the same as the DRV5055, but has a PWM output. This device is also compatible with the Hall adapter EVM, and can be evaluated using the DRV55055-5057EVM (which also has available source code on TI.com).
