MiTuner / Firmware for LayraTD-MSC ZL38063 (AUD-2936) #602

Closed expresspotato closed 3 years ago

expresspotato commented 3 years ago

Since AEC, AGC and NS aren't really very good with the current software algorithm, I'm actively investing doing it with a DAC that supports these in hardware, namely the Espressif Dev Kit LayraTD-MSC with the MicroSemi ZL38063.

https://github.com/espressif/esp-adf/blob/c3b792c1e129f0ccd8877fc082a253ded78e984f/components/audio_hal/driver/zl38063/Readme_twolf.txt

The software links don't work, does anyone know where I can download the firmware / MiTuner / Guide PDF to properly tune / enable these functions?

Hi @expresspotato

I think MSC dsp firmware was updated in ADF, please have a try.

expresspotato commented 3 years ago

Thanks, I see it was updated 17 days ago! Any documentation though on the chip itself (parameters, AEC, AGC, etc)? Seems like the functionality is set via i2c and set in registers once the firmware is loaded but I can find zero documentation on which registers to set for what functionality...

That DSP firmware contains AEC, NS, BF, AGC functions. If you want to get customized firmware, you need to configure it with MSC software.

Okay I'll buy a LayraTD-MSC and give it a go. I've reached out to MSC but just like Qualcomm they're tight lipped about how to actually configure the thing.

Hi, I found following : https://www.microchip.com/wwwproducts/en/ZL38063 Then view datasheet... 63 pages.. Regards Ludo

Thanks, it seems all of it is configured in firmware, then flashed to the device on initialization. There is not much to configure other than switching between pre-configured modes. I'm trying to get the software from micro semi to check if we can evaluate this chip for mass production but it's also taking time.

What happens when the host audio application is configurated differently for music playback vs a call? That's another thing I don't know.

@expresspotato Did you ever get the MiTuner ZLS38508 software? I'm in a similar situation, waiting on their approval.

We found it difficult to work with Microchip, they didn't provide any information and their sales person was quite rude. So we moved onto an older but well working chip from Taiwan.

NathanSweet commented 1 year ago

Ah, damn. Any chance you can share the chip in case I need to go that route?

Yep, Microchip sucks. I went through their partner, filled out a survey, and they don't want to bother. In the meantime I found the Xmos XVF3610 which is much better anyway, so I'll use that. Xmos provides the software without jumping through any hoops and their technology is more modern with more features and better hardware.

I received the MSC software (MiTuner Gui). However, i found the ZL38063 firmware inside the adf repository https://github.com/espressif/esp-adf/tree/master/components/audio_hal/driver/zl38063/firmware in form of a static lib (.a) which contains the compiled object file of the timberwolf firmware. the original timberwolf firmware and config files (.s3 and *.cr2) are are not available. is there any chance to receive receive them from Espressif , so I can fine tune the filters?
