4 Peripherals

Feature List

• Eight channels for sending and receiving infrared remote control signals

• Independent transmission and reception capabilities for each channel

• Clock divider counter, state machine, and receiver for each RX channel

• Supports various infrared protocols

For details, see ESP32 Technical Reference Manual > Chapter Remote Control Peripheral.

Pin Assignment

The pins for the Remote Control Peripheral can be chosen from any GPIOs via the GPIO Matrix.

For more information about the pin assignment, see ESP32 Series Datasheet > Section Peripheral Pin

Configurations and ESP32 Technical Reference Manual > Chapter IO_MUX and GPIO Matrix.

4.2.7 Pulse Counter Controller (PCNT)

The pulse counter controller (PCNT) is designed to count input pulses by tracking rising and falling edges of

the input pulse signal.

Feature List

• Eight independent pulse counter units

• Each pulse counter unit has a 16-bit signed counter register and two channels

• Counter modes: increment, decrement, or disable

• Glitch filtering for input pulse signals and control signals

• Selection between counting on rising or falling edges of the input pulse signal

For details, see ESP32 Technical Reference Manual > Chapter Pulse Count Controller.

Pin Assignment

The pins for the Pulse Count Controller can be chosen from any GPIOs via the GPIO Matrix.

For more information about the pin assignment, see ESP32 Series Datasheet > Section Peripheral Pin

Configurations and ESP32 Technical Reference Manual > Chapter IO_MUX and GPIO Matrix.

4.2.8

LED PWM Controller

The LED PWM Controller (LEDC) is designed to generate PWM signals for LED control.

Feature List

• Sixteen independent PWM generators

• Maximum PWM duty cycle resolution of 20 bits

• Eight independent timers with 20-bit counters, configurable fractional clock dividers and counter

overflow values
