Macros
#define	PWM0_GPIOS { LED0_PIN }
	Declaration of the channels for device PWM_DEV(0)

ADC channel configuration
#define	ADC_GPIOS { GPIO4, GPIO12 }
	Declaration of GPIOs that can be used as ADC channels.

SPI configuration
SPI_DEV(0) is used for the LCD display 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. Otherwise 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
	SPI2 (FSPI) is configured as SPI_DEV(0)

#define	SPI0_SCK GPIO10
	LCD SCLK.

#define	SPI0_MOSI GPIO11
	LCD SDA.

#define	SPI0_MISO GPIO_UNDEF
	LCD SDO (not connected)

#define	SPI0_CS0 GPIO9
	LCD CS.

I2C configuration
I2C_DEV(0) is used for the touch controller. I2C_DEV(1) is connected to the external I2C header. It has a level shifter and is therefore 5V tolerant. 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 GPIO7
	SCL signal of I2C_DEV(0)

#define	I2C0_SDA GPIO6
	SDA signal of I2C_DEV(0)

#define	I2C1_SPEED I2C_SPEED_FAST
	I2C bus speed of I2C_DEV(1)

#define	I2C1_SCL GPIO39
	SCL signal of I2C_DEV(1)

#define	I2C1_SDA GPIO38
	SDA signal of I2C_DEV(1)
