Sigma-delta Modulation
|
|
========
|
|
|
|
Overview
|
|
--------
|
|
|
|
ESP32 has a second-order sigma-delta modulation module.
|
|
This driver configures the channels of the sigma-delta module.
|
|
|
|
Application Example
|
|
-------------------
|
|
|
|
Sigma-delta Modulation example: `examples/14_sigmadelta <https://github.com/espressif/esp-idf/tree/master/examples/14_sigmadelta>`_.
