Hi everyone,

Can I use SPI from BeagleBone Black to connect to one TDC1000/TDC7200 circuit for a water flow measure?

Thanks in advance,

Yes you should be able use beaglebone black SPI, to connect to TDC1000/TDC7200. Why are you having problems?

Thank you Mahendra for your reply,

I intend to use the Beaglebone Black instead of a MSP430FR6989. I was figuring out if there is any tip & trick at circuit or programming level that I need to be concerned about.

Sergio,
The TDC1000_7200EVM uses MSP430F5528 as the MCU controlling the SPI bus. When using an external SPI master like Beaglebone Black, then you need to make sure MSP430 is not active on the SPI bus. Either you can erase the default firmware of the MSP430 or disconnect the resistors connecting MSP430 to TDCs (R6/R7).
Thanks,
Vishy

Vishy,

So I can use the TDC1000 7200EVM circuit changing the connection with MSP430 by Beaglebone Black SPI's, am I right?
Thanks,
Sérgio

Sergio,

This is something you have to explore. MSP430 Firmware source code is part of the GUI software install folder that you might want to use it as reference.

Thanks,

Vishy,

I agree with you, explore is the fun part after all.

Thanks for the tips,

Sergio,

In my experience doing the work on beagle bone black might be much more easy because you can develop software on user space. Also you can take advantage of the unix OS. The big trade off is ultra low power vs power hungry BBB.

Hello Sergio,

I'm looking to do something similar, did you manage to connect SPI to BB in the end? I'm thinking of connecting the evm to a CC2650.

Thanks,

Remi
