Peripheral configurations for ESP32-S3-USB-OTG boards. More...

Detailed Description

Peripheral configurations for ESP32-S3-USB-OTG boards.

Any modifications required for specific applications can be overridden by application-specific board configuration.

For detailed information about the peripheral configuration for ESP32-S3 boards, see section Common Peripherals.

ADC channel configuration
#define	ADC_GPIOS { GPIO1, GPIO2 }
	Declaration of GPIOs that can be used as ADC channels.

PWM channel configuration
#define	PWM0_GPIOS { LED0_PIN, LED1_PIN }
	Declaration of the channels for device PWM_DEV(0)

SPI configuration
SPI_DEV(0) is used for LCD display SPI_DEV(1) is used for SPI SD Card (only configured if `sdcard_spi` is enabled)
#define	SPI0_CTRL SPI2_HOST
	FSPI is configured as SPI_DEV(0)

#define	SPI0_SCK GPIO6
	LCD SCLK.

#define	SPI0_MOSI GPIO7
	LCD SDA.

#define	SPI0_MISO GPIO3
	not used (dummy pin)

#define	SPI0_CS0 GPIO5
	LCD CS.

UART configuration
ESP32-S3 provides 3 UART interfaces at maximum: UART_DEV(0) uses fixed standard configuration. UART_DEV(1) is not used.
