BOOSTXL-SENSORS: Launchpad signal matrix help

Part Number: BOOSTXL-SENSORS

Hi,

I need some guidance on the launchpad and accessories, I want to attach multiple boost-xl modules to receive several analog signals. I would like to collect analog signals from 6-8 sensors, and then the launchpad would do some computations on the 6-8 signals to output 6 signals. The 6-8 signals are load cell signals that require computations/processing using either a 6x6 matrix or a 6x8 matrix to give 3 force outputs and 3 moment outputs for a total of 6 outputs. See example below where the D1-D6 are the analog signals and the R1-R6 are the computed outputs.

Is this possible with the boostxl launchpad? Is there any training/videos to help with this?

Thanks,

  • Hello Adam,

    Looking at the BOOSTXL-SENSORS schematic, its on-board sensors appear to be communicating over I2C. Some sensors may allow you to configure the I2C addresses, so you could connect more than one on the I2C bus. If not, I would recommend using a single BOOSTXL-SENSORS and just duplicate the data for the other (virtual) sensors. Plus, the other analog signals from your other sensors can be connected to the header pins if needed.

    Now, for the host MCU, I would recommend using the MSP-EXP430FR5994 LaunchPad. The MSP430FR5994 features the Low Energy Accelerator (LEA) that can help with matrix multiplication.

    Regards,

    James
