Functions

void board_init (void)
 Initialize the board (GPIO, sensors, clocks).
 

Xtimer configuration

The timer runs at 1000 kHz to increase accuracy, or at 32.768 kHz if LETIMER is used.

#define XTIMER_DEV   (TIMER_DEV(0))
 
#define XTIMER_HZ   (1000000UL)
 
#define XTIMER_WIDTH   (32)
 
#define XTIMER_CHAN   (0)
 

Board controller configuration

Define the GPIO pin to enable the BC, to allow serial communication via the USB port.

#define BC_PIN   GPIO_PIN(PE, 1)
 

Push button pin definitions

#define PB0_PIN   GPIO_PIN(PC, 8)
 
#define PB1_PIN   GPIO_PIN(PC, 9)
 

LED pin definitions

#define LED0R_PIN   GPIO_PIN(PH, 10)
 
#define LED0G_PIN   GPIO_PIN(PH, 11)
 
#define LED0B_PIN   GPIO_PIN(PH, 12)
 
#define LED1R_PIN   GPIO_PIN(PH, 13)
 
#define LED1G_PIN   GPIO_PIN(PH, 14)
 
#define LED1B_PIN   GPIO_PIN(PH, 15)
 
#define LED0_PIN   LED0R_PIN
 
#define LED1_PIN   LED1R_PIN
 

Macros for controlling the on-board LEDs

#define LED0_ON   gpio_set(LED0_PIN)
 
#define LED0_OFF   gpio_clear(LED0_PIN)
 
#define LED0_TOGGLE   gpio_toggle(LED0_PIN)
 
#define LED1_ON   gpio_set(LED1_PIN)
 
#define LED1_OFF   gpio_clear(LED1_PIN)
 
#define LED1_TOGGLE   gpio_toggle(LED1_PIN)
 

Display configuration

Connection to the on-board Sharp Memory LCD (LS013B7DH03).

#define DISP_SPI   SPI_DEV(0)
 
#define DISP_COM_PIN   GPIO_PIN(PA, 11)
 
#define DISP_CS_PIN   GPIO_PIN(PC, 14)
 
#define DISP_EN_PIN   GPIO_PIN(PA, 9)
 

Temperature sensor configuration

Connection to the on-board temperature/humidity sensor (Si7021).

#define SI7021_I2C   I2C_DEV(2)
 
#define SI7021_EN_PIN   GPIO_PIN(PB, 3)
 
#define SI70XX_PARAM_I2C_DEV   SI7021_I2C
 

Core temperature sensor configuration

Connection to the on-chip temperature sensor.
