MSP430FR6043: Code and hardware Modification

A A8

Part Number: MSP430FR6043
Other Parts Discussed in Thread: TMUX1209

Hi,

I am Looking forward to do a setup as mentioned in the SLAA969 Application note for High speed Anemometer. For which I have purchased the 200khz transducers as mentioned and now I would like to connect the same on the EVM430 Kit but as the EVM430 BOARD does not have a onboard TMUX1209 I want to connect it externally but as per the application note a software-controlled GPIO from the MSP430FR6043 has to be connected to pin A0 of the TMUX1209 to take alternating measurements between the two transducer pairs and the EVM board does not have a free GPIO on board as well as there is no provision in the code for interface of TMUX1209. Please help me how to make connection and make this work using the development kit.

Regards,

Aishwarya

Your understanding is correct: the TMUX1209 should be on another board to connect to the MSP430FR6043 EVM.

From TIDM2003 board schematic, there are 2 signals not used: TxSel, XPB0. They are on connector J10, and you can find which GPIOs are connected to these two signals and select one for TMUX1209 control signal A0.

Sorry, I am not clear about the source code. Please read the code and modify the code by yourself. It should be not difficult.
