Firmware files

[JacSko]

Hi,

Really nice project! I'm working on portable, ESP-based AM/FM/DAB receiver and looking for a firmware (especially for AMFM mode). Is there any chance, that You have such and could share with me?

The firmware for the Si468x series is proprietary and typically distributed under NDA, so it can't be shared publicly.

You might find useful background information and discussions in community forums such as:
