MSP432P401R: Where can I find slaa681 file?

Ray Buck

Part Number: MSP432P401R

I have read the document "BPSK Modem Implementation With SimpleLink MSP432 MCUs". The link to download the slaa681 file is broken and searching doesn't turn up anything.

I have purchased two of the MSP‑EXP432P401R launchpad boards to test the BPSK transmission. I am more interested in decoding BPSK than encoding it. But the 2 board test setup described in the document will help me understand the demodulation process. I only need to decode 4 bytes of data per second so my requirement is much less demanding than the 125 kbps described in the article.

Does anyone know how I can obtain the slaa681 zip file?

The AppNote is said to be decommissioned, but the .pdf and .zip were supplied (sub rosa, no support) over here:

This thread may also be of interest, since it discusses some refinements:

Bruce, thanks for the links. I was able to download the file. I also read through the other links concerning refinements. Maybe I will be able to make the BPSK modulator/demodulator pair work. My goal is to ultimately have the pair work over a 433 MHz wireless link.

It would be nice if TI could create a new project that actually worked using the MSP‑EXP432P401R LaunchPad boards.
