Detailed Description

Board specific definitions for Espressif ESP-WROVER-KIT V3.

The Espressif ESP-WROVER-KIT is a development board that uses the ESP32-WROVER module which includes a built-in 4 MByte SPI RAM. Most important features of the board are

Micro-SD card interface
OV7670 camera interface
3.2" SPI LCD panel
RGB LED

Furthermore, many GPIOs are broken out for extension. The USB bridge based on FDI FT2232HL provides a JTAG interface for debugging through the USB interface.

When the camera module is connected, add

USEMODULE += esp32_wrover_kit_camera

to the makefile of the application to use the according default board configuration.

For detailed information about the configuration of ESP32 boards, see section Common Peripherals.

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

LED (on-board) configuration
#define	LED0_PIN GPIO0
	LED0 is available when the camera is not plugged in.

#define	LED0_ACTIVE (1)
	LED0 is high active.

#define	LED1_PIN GPIO2
	LED1 is available when the SD-Card is not used.

#define	LED1_ACTIVE (1)
	LED1 is high active.

#define	LED2_PIN GPIO4
	LED2 is available when the camera is not plugged in.

#define	LED2_ACTIVE (1)
	LED2 is high active.

#define	LED_RED_PIN LED0_PIN
	LED0 is a red LED.

#define	LED_GREEN_PIN LED1_PIN
	LED1 is a green LED.

#define	LED_BLUE_PIN LED2_PIN
	LED2 is a blue LED.

SD-Card interface configuration
The SD-Card interface is connected to the HSPI interface. Since HSPI becomes SPI_DEV(0) when the camera is connected, the SD card interface uses SPI_DEV(0) in this case. Otherwise, SPI_DEV(1) is used. This configuration cannot be changed.
#define	SDCARD_SPI_PARAM_SPI SPI_DEV(0)
	SPI_DEV(0) is used when camera is connected.

#define	SDCARD_SPI_PARAM_CLK SPI0_SCK
	HSPI SCK is used (fixed)

#define	SDCARD_SPI_PARAM_MOSI SPI0_MOSI
	HSPI MOSI is used (fixed)

#define	SDCARD_SPI_PARAM_MISO SPI0_MISO
	HSPI MISO is used (fixed)

#define	SDCARD_SPI_PARAM_CS SPI0_CS0
	HSPI CS1 is used (fixed)

#define	SDCARD_SPI_PARAM_POWER GPIO_UNDEF
	power control is not used (fixed)

LCD configuration
This configuration cannot be changed.
#define	LCD_CS GPIO22

#define	LCD_RST GPIO18

#define	LCD_DC GPIO21

#define	LCD_BACKLIGHT GPIO5

#define	BACKLIGHT_ON gpio_clear(LCD_BACKLIGHT)

#define	BACKLIGHT_OFF gpio_set(LCD_BACKLIGHT)

#define	ILI9341_PARAM_SPI SPI_DEV(1)

#define	ILI9341_PARAM_SPI_CLK SPI_CLK_10MHZ

#define	ILI9341_PARAM_CS LCD_CS

#define	ILI9341_PARAM_DCX LCD_DC

#define	ILI9341_PARAM_RST LCD_RST

#define	ILi9341_PARAM_RGB 0

#define	ILI9341_PARAM_INVERTED 0

#define	ILI9341_PARAM_ROTATION ILI9341_ROTATION_HORZ_FLIP
