MSP430FR6043: Using multiplexer and using at least 2 MSPs together with another device

Tool/software:

Hi MSP team,

I have two questions in regards to a project that I'm doing on my own.

1. Is it doable to use a multiplexer with MSP430 in order to use more than 1 set of ultra sound transducers? For example TS5A9411 from this eerd https://www.ti.com/tool/TIDM-02005 ?

2. If not, can 2 MSPs be synchronized by another device in order to take more than 1 measurement from the same pipe?

Thanks for any help and suggestions,

Adam

Hi Adam, thanks for the question! Are you needing these to be done simultaneously, or just one after the other. Using a mux, you will need to consider the channel-to-channel switch time and the settling delay as well. You could probably use 2 MSPs if this needs to be done simultaneously, but there could be issues with clk sync, etc.

Hi Brian,

If using 2 MSPs together and specifically theirs EVMs modules is an option, could you maybe confirm info from this old post https://e2e.ti.com/support/microcontrollers/msp-low-power-microcontrollers-group/msp430/f/msp-low-power-microcontroller-forum/554542/connecting-two-msp430-launchpad-together-through-i2c that such connection is possible via I2C port?

Cheers,

Adam

Hi Adam, yes I think this information is still valid for your application.
