Peripheral configurations for ESP32 ProS3 boards. More...
Peripheral configurations for ESP32 ProS3 boards.
The peripheral configurations in this file can be used for Espressif ESP32 ProS3x board.
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 and DAC channel configuration | |
#define | ADC_GPIOS { GPIO1, GPIO2, GPIO3, GPIO4, GPIO5, GPIO6, GPIO7, GPIO8, GPIO9, GPIO10 } |
Declaration of GPIOs that can be used as ADC channels. | |
I2C configuration | |
For generic boards, only one I2C interface I2C_DEV(0) is defined. The GPIOs listed in the configuration are only initialized as I2C signals when module | |
#define | I2C0_SPEED I2C_SPEED_FAST |
I2C bus speed of I2C_DEV(0) | |
#define | I2C0_SCL GPIO9 |
SCL signal of I2C_DEV(0) | |
#define | I2C0_SDA GPIO8 |
SDA signal of I2C_DEV(0) | |
PWM channel configuration | |
Two PWM devices are configured. These devices can use all GPIOs that are not defined as I2C, SPI or UART for this board. Generally, all outputs pins could be used as PWM channels.
| |
#define | PWM0_GPIOS { GPIO12, GPIO13, GPIO14, GPIO15, GPIO16 } |
Declaration of the channels for device PWM_DEV(0), at maximum PWM_CHANNEL_NUM_DEV_MAX. | |
#define | PWM1_GPIOS { GPIO6, GPIO7, GPIO21, GPIO38 } |
Declaration of the channels for device PWM_DEV(1), at maximum PWM_CHANNEL_NUM_DEV_MAX. | |
SPI configuration | |
| |
#define | SPI0_CTRL FSPI |
FSPI is used as SPI_DEV(0) | |
#define | SPI0_SCK GPIO36 |
FSPI SCK (pin FSPICLK) | |
#define | SPI0_MISO GPIO37 |
FSPI MISO (pin FSPIQ) | |
#define | SPI0_MOSI GPIO35 |
FSPI MOSI (pin FSPID) | |
#define | SPI0_CS0 GPIO34 |
FSPI CS0 (pin FSPICS0) | |
UART configuration | |
ESP32-S3 provides 3 UART interfaces at maximum: UART_DEV(0) uses fixed standard configuration. | |
#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 | |
#define ADC_GPIOS { GPIO1, GPIO2, GPIO3, GPIO4, GPIO5, GPIO6, GPIO7, GPIO8, GPIO9, GPIO10 } |
Declaration of GPIOs that can be used as ADC channels.
All pins of ADC1 are declared as ADC channels. Keep in mind that GPIO10 is not broken out and used as VBAT signal. GPIO3 is a strapping pin if EFUSE_STRAP_JTAG_SEL
is set, see Strapping pins.
