Detailed Description

Peripheral MCU configuration for Wemos D1 R32 (ESPDuino-32) board.

The peripheral configuration corresponds to the Arduino Uno pinout and guarantees the compatibility with Arduino Uno Shields.

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

ADC and DAC channel configuration
#define	ADC_GPIOS { GPIO2, GPIO4, GPIO35, GPIO34, GPIO36, GPIO39 }
	Declaration of GPIOs that can be used as ADC channels.

#define	DAC_GPIOS { GPIO25, GPIO26 }
	Declaration of GPIOs that can be used as DAC channels.

PWM channel configuration
#define	PWM0_GPIOS { GPIO25, GPIO16, GPIO27, GPIO13, GPIO2 }
	Declaration of PWM_DEV(0) channels, at maximum six channels.

#define	PWM1_GPIOS { GPIO5, GPIO23 }
	Declaration of PWM_DEV(1) channels, at maximum six channels. More...

SPI configuration
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 VSPI
	VSPI is used as SPI_DEV(0)

#define	SPI0_SCK GPIO18
	VSPI SCK.

#define	SPI0_MISO GPIO19
	VSPI MISO.

#define	SPI0_MOSI GPIO23
	VSPI MOSI.

#define	SPI0_CS0 GPIO5
	VSPI CS0.

UART configuration
UART_DEV(0) uses fixed standard configuration. UART_DEV(1) is defined here.
#define	UART0_TXD GPIO1
	direct I/O pin for UART_DEV(0) TxD, can't be changed

#define	UART0_RXD GPIO3
	direct I/O pin for UART_DEV(0) RxD, can't be changed

#define	UART1_TXD GPIO17
	direct I/O pin for UART_DEV(1) TxD

#define	UART1_RXD GPIO16
	direct I/O pin for UART_DEV(1) RxD

Macro Definition Documentation

#define PWM1_GPIOS { GPIO5, GPIO23 }

Declaration of PWM_DEV(1) channels, at maximum six channels.

GPIO5 and GPIO23 are also used for SPI_DEV(0) an can only be used as PWM channels if SPI_DEV(0) is not used an vice versa.
