VGA + VS1053B

For the lucky owners of the VGA output, try this code : (pumped from elsewhere)

Mesmerising. And that's even without the VS1053 which I only just ordered today... I do love the VGA capability.

Have you tried pairing the sounds to a bluetooth speaker device yet ?

Never tested but the Bluetooth functionality requires too much memory so is much easier to use an external Bluetooth adapter sold for very cheap. In this specific case (the vs1053b) it is the only option as the sound is generated externally.
Anyway, I'll give a try.

Just for fun, for a pure performance exercise, I did the same using javascript

Wow, some sentence... doing javascript purely as a fun performance exercise !
The demo is great BTW, so could be useful to post its code in HTML Stuff for us to look at and perhaps learn from.

[cicciocb]

The term "performance" was related to the graphic performances of the browser

The code source is very simple, you can just obtain it doing right click on the page and then "view page source".
It is essentially the same code for the basic plus some additional html elements.

You can eventually copy / paste it into a file.html and then play freely with it.

S3 N16R8 is about as powerful and capable as Annex gets, so should be an interesting test.

BTW, just had confirmation from JLCPCB that their incorrect SMT assembly weight over-estimate resulted in 200% price overestimate, so instead of ten S3 N16R8 VGA PCBs with the SMT VGA resistors pre-installed costing 40€ (with slow delivery) it will now cost less than 20€, which is much more acceptable. Could be a welcome precedent for anyone who has been previously put off SMT pre-assembly by over-priced estimates.

I've got one of the red boards the same as Electroguard's on which I did a (very fiddly) cut and link hardware mod to make it boot up in serial mode with access to the midi instruments over serial interface for a simple rhythm generator box. Francesco, does your support for this chip give access to the instrument wavetables?

I've a good news for you, I've implemented the support for the midi files and also the access to the midi command (notes, instruments , ..)

WOW! The man is unbelievable
Ordering a couple of new VS1053 boards today. And a couple of S3 boards too.

[cicciocb]

You don't need a -S3, it will work also with the classic ESP32 (probably all the ESP32)
