	I am including an Arduino library for the Dallas Semi DS18B20 temp sensor and the INO file does not compile. My target device is the ESP32S3 Dev Module. The error message is: Arduino.h:36: In file included from OneWire.cpp:142: from OneWire_direct_gpio.h: In function void directModeInput(uint32_t) OneWire_direct_gpio.h: 191:38: error: 'esp32_gpioMux' was not declared in this scope ESP_REG(DR_REG_IO_MUX_BASE + esp32_gpioMux[pin].reg) = pinFunction ^~~~~~~~~~~~~ esp32-hal.h:73: note in definition of macro ESP_REG #define ESP_REG(addr) ((volatile uint32_t )(addr)) ^~~~ OneWire_direct_gpio.h: In function void directModeOutput(uint32_t) OneWire_direct_gpio.h: 232:38: error: 'esp32_gpioMux' was not declared in this scope ESP_REG(DR_REG_IO_MUX_BASE + esp32_gpioMux[pin].reg) = pinFunction ^~~~~~~~~~~~~ esp32-hal.h:73: note in definition of macro ESP_REG Error compiling libraries #define ESP_REG(addr) ((volatile uint32_t )(addr)) ^~~~ Debug build failed for project 'test'

	Thanks for the report. The OneWire Library needs to be upgraded to v2.3.7 to add the ESP32 support: https://github.com/PaulStoffregen/OneWire/releases/tag/v2.3.7
