XBEE1 bus

XBEE1 is enabled by default.

The enable pin is 'XBEE1_EN_PIN'. To disable this bus call 'XBEE1_DISABLE', to re-enable it call 'XBEE1_ENABLE'.

#define XBEE1_EN_PORT   PORT->Group[PB]
 
#define XBEE1_EN_MASK   (1 << 3)
 
#define XBEE1_EN_MODE   GPIO_OUT
 
#define XBEE1_EN_PIN   GPIO_PIN(PB, 3)
 
#define XBEE1_ENABLE   (XBEE1_EN_PORT.OUTCLR.reg = XBEE1_EN_MASK)
 
#define XBEE1_DISABLE   (XBEE1_EN_PORT.OUTSET.reg = XBEE1_EN_MASK)
 
#define XBEE1_CS_PIN   GPIO_PIN(PA, 18)
 
#define XBEE1_INT_PIN   GPIO_PIN(PA, 21)
 

XBEE2 bus

XBEE2 is enabled by default.

The enable pin is 'XBEE2_EN_PIN'. To disable this bus call 'XBEE2_DISABLE', to re-enable it call 'XBEE2_ENABLE'.

#define XBEE2_EN_PORT   PORT->Group[PB]
 
#define XBEE2_EN_MASK   (1 << 10)
 
#define XBEE2_EN_PIN   GPIO_PIN(PB, 10)
 
#define XBEE2_EN_MODE   GPIO_OUT
 
#define XBEE2_ENABLE   (XBEE2_EN_PORT.OUTCLR.reg = XBEE2_EN_MASK)
 
#define XBEE2_DISABLE   (XBEE2_EN_PORT.OUTSET.reg = XBEE2_EN_MASK)
 
#define XBEE2_CS_PIN   GPIO_PIN(PA, 14)
 
#define XBEE2_INT_PIN   GPIO_PIN(PA, 15)
 

I2C bus

I2C is enabled by default.

The enable pin is 'I2C_EN_PIN'. To disable this bus call 'I2C_DISABLE', to re-enable it call 'I2C_ENABLE'.

#define I2C_EN_PORT   PORT->Group[PB]
 
#define I2C_EN_MASK   (1 << 11)
 
#define I2C_EN_PIN   GPIO_PIN(PB, 11)
 
#define I2C_EN_MODE   GPIO_OUT
 
#define I2C_ENABLE   (I2C_EN_PORT.OUTSET.reg = I2C_EN_MASK)
 
#define I2C_DISABLE   (I2C_EN_PORT.OUTCLR.reg = I2C_EN_MASK)
