Re: Recording sounds without external codec

It could be just static or something. Or you don't need an amplifier.

Question to you have your code up somewhere. I am interested in getting sound in and out thru the ADC and DAC also and haven't found many examples.

Re: Recording sounds without external codec

I am also interested in this. Considering the on board ADC has a more then high enough sampling rate and has a high-ish bit depth it should work fine. Just depends on it you can actually set it up. Even with the 6khz filtering sort of stuff its fine considering thats about as wide as a SSB conversat...

Re: Max size of Flash memory that can be used? ESP32

I only have an ESP-WROOM to use. I was asking to figure out if you could use say a larger flash and just dynamically swap which blocks are mapped into the address space.

Max size of Flash memory that can be used? ESP32

I am wondering what the max size of flash memory that can be attached to the ESP32. Like I know only 16MB can be mapped at once but does that mean you can have a large flash and just map a different 16MB to access more of the chip. (Losing access to that first 16MB of course until you map back to it...

Re: Documentation Requests/Feedback

Thats very confusing mentions internal details about the DAC and ADC attached to the MACs if they weren't somehow relevant to using the Core.

Re: Documentation Requests/Feedback

I would like too request documentation of the SDR like part of the ESP32 core. (Specifically the two High speed DACs and ADCs used in quadrature to form the 2.4 Ghz Radio.) The only mention of them is the Technical docs. And only mention their existence and now how they are connected or how to use t...
