I've been looking for specs for sending audio to USB-C headphones and I can't seem to find any information. I know that you can send analog audio over USB-C using the D+/- line but I'd also like to send digital audio for headphones capable of that. Is this something you've tried? Do you know what pr...

Hey guys - Finally getting back to my project here! I had settled on the 1053 but going back to considering the 1010 again. My design goal is to have a totally self-contained player/recorder recording to an SD card. All recording would be done via a stereo analog line-in or a MEMs mic. Going through...

Hi Panu - Getting started revitalizing my project with the 1053. I have both of your books but I'm wondering if you can recommend any books to get started with the core electronic principles. Something to really dive in and understand the workings of the filters, reasons for caps and resistors and a...

Thanks for bearing with me Pasi. I'm still a bit lost. I'd prefer to have the SD directly connected to the 1053 and use the arduino to control operation. The SD card will be internal to the device so there will be no swapping or need for CD. Can you provide some more details on how I should set this...

Hey Pasi- Thanks for the info. I've redone the layout to use the arduino and the vs1053 as the slave. Can you look if this looks alright so far? Again, I'm not dealing with any signal interference, isolation, filtering, etc. just yet. 23 is the chip select pin right? I was unsure if it should be 13....

Wow, good call on the chip orientation. I've been using a socket adapter and the alignment corner was wrong. Using a fresh chip I hooked everything up and I'm no longer getting a spike in amps, the crystal is working, and voltages are good. I'm just not getting playback now so I'm sure I'm close. He...

Hi Panu - Thanks for the info!! I'm using an SD card for storage. Looking more at the 1010, this chip doesn't have line-in encoding does it? I want to be able to record both digital MEMS and analog line-in. I think you're saying I would need an external DAC for that? I'd prefer to avoid adding anoth...

I'm working on a super basic MP3 player to be part of a consumer product. I've never worked with audio or chips like this so I'm wondering if there's anyone who is willing to consult or help with the design of this portion of the design. Please let me know!

Hi, I'm working on a simple project using the 1053 that I want to have the following functionality: 1. Record input to a single track (or treated as a single track during playback) 2. Allow only 2 hours of recording 3. Use LEDs to indicate where you are in the track (example: 4 LEDs that light up wh...

Thanks for that quick reply! This is my first adventure into these ICs, I normally have worked only with coding Arduinos so editing the firmware isn't something I know how to do (yet!) I'm going to explore VSIDE but can you elaborate just a little on where I would "Set the codec services struct...
