In the ESP32 module the built-in DAC and ADC are used for audio in and output, which provide just about enough resolution for voice communication. So why use ESP-NOW rather than WiFi or Bluetooth?
Even so, together with simple VGA output using a DAC, this library provides yet another way to add analog video output to ubiquitous MCUs like the ESP32. Even if these MCUs are not going to be ...
It is common for an ADC or DAC to be required to meet a SFDR (spurious free dynamic range) specification. Definition: “Spurious-free dynamic range (SFDR) is the strength ratio of the fundamental ...
