I have one on order but have not yet received it. For me, with some experience programming chips, I was going to look at the demo code to see how the registers are programmed. That means downloading the datasheet for the chip and studying the registers. There is also help in the vlsi.fi website. Then I was going to modify the code to my liking, including adding a display. But this is just a plan.
I don’t know what your goals are but for a beginner, programming a chip like this is probably too complex.
BTW, that board is “dirt cheap”. Just the vs1053 chip will cost you $20 elsewhere…
