| * @brief Board defitions 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. | ||
| * | ||
| * Board configuration defined in this file is: | ||
| * | ||
| * Pin | Defined Function | Prerequisites / Remarks | ||
| * :------|:-------------------------|:---------------------------------- | ||
| * GPIO0 | LED red / PWM_DEV(0):0 | Camera not connected | ||
| * GPIO2 | LED green / PWM_DEV(0):1 | SD Card interface not used | ||
| * GPIO4 | LED blue / PWM_DEV(0):2 | Camera not connected | ||
| * GPIO5 | I2C_DEV(0):SCL | Camera not connected | ||
| * GPIO27 | I2C_DEV(0):SDA | Camera not connected | ||
| * GPIO19 | SPI_DEV(0):SCK | Camera not connected | ||
| * GPIO23 | SPI_DEV(0):MOSI | Camera not connected | ||
| * GPIO25 | SPI_DEV(0):MISO | Camera not connected | ||
| * GPIO22 | SPI_DEV(0):CS0 | Camera not connected | ||
| * GPIO1 | UART_DEV(0):TxD | Console (cannot be changed) | ||
| * GPIO3 | UART_DEV(0):RxD | Console (cannot be changed) | ||
| * GPIO26 | DAC:0 | Camera not connected | ||
| * GPIO12 | ADC:0 | | | ||
| * GPIO36 | ADC:1 | Camera not connected | ||
| * GPIO39 | ADC:2 | Camera not connected | ||
| * GPIO9 | Digital In/Out | SPI RAM not used, used as CS for MRF24J40, ENC28J60 | ||
| * GPIO10 | Digital In/Out | SPI RAM not used, used as RESET for MRF24J40, ENC28J60 | ||
| * GPIO13 | Digital In/Out | SD Card interface not used | ||
| * GPIO14 | Digital In/Out | SD Card interface not used | ||
| * GPIO15 | Digital In/Out | SD Card interface not used | ||
| * GPIO34 | Digital In | used as INT for MRF24J40, ENC28J60 | ||
| * GPIO35 | Digital In | | | ||
| * | ||
| * **PLEASE NOTE:** | ||
| * LCD and camera can not be used at the same time as both use the same | ||
| * signals. The availability of some peripherals depends on the use of the | ||
| * camera and the SD card interface. | ||
| * | ||
| * **PLEASE NOTE:** | ||
| * Most of the board defitions can be overriden by an application specific | ||
| * board configuration file. For that purpose, a header file located in | ||
| * application directory can be specified using the BOARD_APP_CONF make | ||
| * variable at command line, for example: | ||
| * | ||
| * BOARD_APP_CONF=esp32_wrover_kit_conf.h | ||
| * | ||
| * If this option is defined, the given file is included from application | ||
| * source directory. | ||
