Code examples for this API section are provided in the peripherals directory of ESP-IDF examples.

Feb 23, 2018 · The three peripheral blocks that I’ll be covering are: The Remote Control peripheral; The Pulse Counter peripheral; The LEDC controller peripheral; I’ll also briefly discuss the I 2 S and DAC/Cosine Generator blocks and provide some routines that enable you to generate some useful signals using these blocks.

The RMT (Remote Control Transceiver) peripheral was designed to act as an infrared transceiver. However, due to the flexibility of its data format, RMT can be extended to a versatile and general-purpose transceiver, transmitting or receiving many other types of signals.

Peripheral is using event_iface to control the event, all events are send out to event_iface queue. This function will be useful in case we want to read events directly from the event_iface queue. Parameters

BLE Peripheral Example (See the README.md file in the upper level 'examples' directory for more information about examples.) This example creates GATT server and then starts advertising, waiting to be connected to a GATT client.

Learn about SPI communication protocol with the ESP32 using Arduino IDE. We’ll take a look at the ESP32 SPI pins, how to connect SPI devices, define custom SPI pins, how to use multiple SPI devices, and much more.

ESP32 Peripheral Drivers built with ESP-IDF. This top-level driver collection provide high-level functions to operate the peripherals. If you are using ESP-IDF and cmake, clone it into the components directory of your project.

Sep 8, 2021 · we are using esp-idf 4.3 and using the device as both BLE peripheral and BLE central. When the central is trying to connect to a device using function ble_gap_connect it is impossible for a central device (mobile phone in this case) to connect to the peripheral.

Nov 16, 2015 · In a separate thread there was an excellent suggestion for using the "RMT peripheral" for part of a project (driving WS2811/WS2812/NeoPixels). See: http://esp32.com/viewtopic.php?f=13&t=293

It provides a common interface for all peripherals and is used to access the peripheral’s registers. It is primarily designed to be used as a base class for peripheral classes that communicate using I2C (address-based) or SPI (CS-based) protocols.
