Can anyone tell me if the VS1053B is also supported? With these offers, you often don't know which chip you're getting...

Hi Frank,
this is what Google says about it:

Quote Overview with AI

The difference between VS1053 and VS1053B is minimal, as "VS1053B" is the correct designation for VLSI Solution's versatile audio codec chip, which decodes a wide variety of formats (MP3, AAC, Ogg Vorbis, WMA, MIDI, FLAC, WAV) and even enables recording and DSP functions (bass, treble, volume). Often, "VS1053" is simply used as an abbreviation, but the "B" denotes the specific version with hardware support for the MIDI synthesizer feature.

Key differences (implicit):

VS1053B (often the "B" is omitted): This is the full name of the chip that supports the extended functionality, such as the integrated General MIDI synthesizer.

VS1053: Often used synonymously, but if there were a difference, it would be an older version without the MIDI synth capabilities; however, in practice, today's breakout boards are mostly the B version.

...

I have a VS1053B module, but it's been lying unused and unconnected for over a year.

So I can't say for sure, but I would always buy a VS1053B!
Kind regards und guten Rutsch!

Michael

Assuming the AI is correct then MMbasic expects the B version as it supports MIDI synthesis

I have a "B" type which I tried with a 2350B(A2) on pins higher than GP29

It gives some output but scrambled and with delays (1sec until MP3 starts to play) and loud cracks.
Unless you want to have MIDI and predefined instruments like piano etc. I cannot suggest this. Maybe it runs better if setup on GPs < 30

I don't trust this AI information. I would prefer someone to confirm that the “B” variant works.

@dddns: THANK YOU! - Unfortunately, that doesn't sound very encouraging...

@matherp: Thanks, I hope you're right about that...

Note: ddns seems to have problems with pins over GP29. I don't. For example the HDMI reference board uses 29,30,31 and 32 for sd and works perfectly. The Palm Pico I'm developing uses every pin on the RP2350B and works perfectly including 42,43,44 for system spi, 41 for sd-cs and 46 for touch irq
