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.
#define	UART0_TXD   GPIO43
	direct I/O pin for UART_DEV(0) TxD, can't be changed
#define	UART0_RXD   GPIO44
	direct I/O pin for UART_DEV(0) RxD, can't be changed

ADC_GPIOS

#define ADC_GPIOS   { GPIO1, GPIO2 }

Declaration of GPIOs that can be used as ADC channels.

GPIO1 can be used for USB_DEV voltage monitoring as ADC_LINE(0). GPIO2 can be used for Battery voltage monitoring as ADC_LINE(1).
