BOOSTXL-PGA460:

Part Number: BOOSTXL-PGA460
Other Parts Discussed in Thread: MSP-EXP430F5529LP, PGA460, ENERGIA

Tool/software:

Hello,

I'm looking to buy a BOOSTXL-PGA460 for research purposes, but had some questions about capabilities that I'd like to ask before I purchase.

1. How easy is it to interface the BOOSTXL-PGA460 to a microcontroller/microcomputer? 

2. Are we able to program a script that triggers the BOOSTXL-PGA460 and then is able to receive and read the raw data?

Thank you,

Olivia

    Hello Olivia,

    Thanks for posting to the sensors forum!

    1. The BOOSTXL-PGA460EVM is made to connect directly to an MSP-EXP430F5529LP microcontroller. So if you are open to using this it will be fairly easy to interface the EVM with a microcontroller since the modules pinout is already set to match with the launchpad. If you have another MCU you can jumper some signals over to the board but it might requires some additional work. Regardless of your choice I still strongly encourage the purchase of both the MCU and EVM since the PGA460 is a very feature heavy device so using the GUI that requires the suggested MCU is strongly encouraged.
    2. We do have an Energia library and code examples for the PGA460 in which you can create something that does this fairly easily. You can check out the example code and libraries here:https://www.ti.com/tool/download/SLAC741. I don't believe we have code that shows you how to read the direct RAW ADC from the PGA460 if this is something you are looking for. But we do have code to read the down-sampled results.

    I hope this helps!

    Best,

    Hi Isaac,

    Thank you for your quick reply.

    What is the down-sampled rate? Also, is there a way to get the RAW ADC values at all in that way, or through the GUI?

    We would need the RAW ADC values for our project.

    Thank you again,

    Olivia

    Hello Olivia,

    This is the data-dump feature on the device that provides 128-bytes of data regardless of your measurement time. The sample rate of the data does not change so its still 1us/sample but the output of the data is what is down-sampled to the 128 bytes. Yes you can get raw ADC data from the GUI or through a MCU I just dont think we have example code on how to do it.

    You are welcome, always glad to help out!

    Best,

    Isaac
