The DTMF decoder hardware may not be necessary. The ESP32 should be capable of decoding a DTMF natively, perhaps by feeding straight into the analog input.

Struggled to make this work, and re-introduced the MT8870 DTMF decoder. Which is a shame, as I could use those 5 pins for something else!! Will have another stab later.
