LAUNCHXL-F28379D: Compatibility to BOOST-DAC8568

Part Number: LAUNCHXL-F28379D
Other Parts Discussed in Thread: BOOST-DAC8568, MSP430F5529, DAC128S085EVM, DAC8568

Hi,

Good Day.

We have a Delfino F28379D Launchpad board and are wondering about compatibility with the BOOST-DAC8568 Booster Pack.

The Delfino board already has 3DACs on board but we would like at least 8 more in adding the booster pack can we also have access to the 20 ADC channels?

So we are wanting to use the Delfino launch pad board for a multi-channel Active noise control system, so in real-time receiving data through multiple ADCs and sending data to multiple DACs. The point of this inquiry is we need more DACs than are currently available, would this booster pack be compatible (BOOST-DAC8568) and give us additional outputs to the current 3 on the board? How many ADC channels can we have with the current Delfino F28379D Launchpad board? And do you offer any other products which would achieve this?

I have looked but the boost pack documentation only has the MSP430F5529 microcontroller LaunchPad as the example, and it doesn't come under the F28379D documentation.

Although it's the same pin layout so should it just work fine.

Please advise. Thank you very much.

Best Regards,

Ray Vincent

    You could look into using PWM DAC method instead. See https://www.ti.com/lit/spraa88

    The BOOST-DAC8568's MOSI pin is not on the standard location for LaunchPads (it's one pin off), but you could jump the signal over. You would have to develop some software driver for interfacing with the DAC8568. Alternatively, you could look at the DAC128S085EVM instead, which I know we do have some C2000 driver support for in our reference solutions.

    Best,
