Hi, I recently came across this Github library for PCM5142 and other family members: https://github.com/SilverSho0t/PCM5142
Has anybody hare used this lib? My primary interest is to run the chip with custom FIR filter coefficients.
Both the code and TI use the word "DSP program". Would that be a binary or a coefficient file? Either way, is there documentation on how to write those?
I have been in contact with TI support which basically said "there used to be a code but we pulled it from the market and you get nothing". They do offer some ways to write biquad and mixer parameters but not FIR or full-blown custom DSP code.
I'm quite happy with the PCM5142 out of the box. But I have a library of special FIR filters that I would really like to move from my $$$$$ Xilinx FPGA + PCM1704 prototype and into something with a bit more widespread availability
Any info on PCM5142 DSP core welcome!
Thanks,
Børge
