Peripheral configurations for ESP32-S3-Box boards. More...

Detailed Description

Peripheral configurations for ESP32-S3-Box boards.

The peripheral configurations in this file are for the Espressif ESP32-S3-Box.

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.

Note: Most definitions can be overridden by an application-specific board configuration if necessary.

I2C configuration
I2C_DEV(0) is available at the PMOD1 connector. Note The GPIOs listed in the configuration are only initialized as I2C signals when module `periph_i2c` is used. Otherwise they are not allocated and can be used for other purposes.
#define	I2C0_SPEED I2C_SPEED_FAST
	I2C bus speed of I2C_DEV(0)

#define	I2C0_SCL GPIO40
	SCL signal of I2C_DEV(0)

#define	I2C0_SDA GPIO41
	SDA signal of I2C_DEV(0)

SPI configuration
SPI_DEV(0) is available at the PMOD2 connector. SPI_DEV(1) is used for the LCD display with an ILI9342C as driver chip. Note The GPIOs listed in the configuration are first initialized as SPI signals when the corresponding SPI interface is used for the first time by either calling the `spi_init_cs` function or the `spi_acquire` function. That is, they are not allocated as SPI signals before and can be used for other purposes as long as the SPI interface is not used.
#define	SPI0_CTRL SPI2_HOST
	FSPI is used as SPI_DEV(0)

#define	SPI0_SCK GPIO12
	FSPI SCK (pin FSPICLK)

#define	SPI0_MISO GPIO13
	FSPI MISO (pin FSPIQ)

#define	SPI0_MOSI GPIO11
	FSPI MOSI (pin FSPID)

#define	SPI0_CS0 GPIO10
	FSPI CS0 (pin FSPICS0)

#define	SPI1_CTRL SPI3_HOST
	SPI3 is used as SPI_DEV(1)

#define	SPI1_SCK GPIO7
	LCD_SCK.

#define	SPI1_MISO GPIO35
	not used and not broken out on ESP32-S3-WROOM-1

#define	SPI1_MOSI GPIO6
	LCD_SDA.

#define	SPI1_CS0 GPIO5
	LCD_CS.

UART configuration
UART_DEV(0) is available at the PMOD2 connector.
#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
