Function Documentation

void system_enable_sx_clock ( uint8_t en )

Enables/disables the radio IC's clock.

Parameters

en	1 enable the clock, 0 to disable it.

void system_enable_sx_power ( uint8_t en )

Powers up/down the radio IC.

Parameters

en	1 to power up the radio IC, 0 to power it down.

void system_init ( void )

Initializes the system (IOs, clocks, ...).

Note: This function is used by the scheduler and should not be called anywhere else.

void system_register_lowpower_pins ( io_pin_t * pins )

Registers additional pins whose configuration and state must be kept when the board/device is in low-power sleep mode.

Note: Any pin whose function cannot dynamically change should be declared in boards.h instead.

Parameters

pins	The pins to register.

void system_set_dcdc_high_power ( uint8_t en )

Switches the DC-DC converter to high-power mode.

If the DC-DC converter of the board supports different power modes, this function allows to switch from low-power to high-power mode.

Parameters

en	1 to enable the high power mode, 0 to disable it.

void system_set_sx_nss ( uint8_t state )

Sets to HIGH or LOW the radio nSS (inverted slave select) pin (for SPI communication).

Parameters

state 1 for HIGH the pin (deselects the radio IC), 0 for LOW (selects the radio IC).

void system_set_sx_rst ( uint8_t state )

Sets to HIGH, LOW, or floating the radio reset pin (for SPI communication).

Parameters

state 1 for HIGH the pin, 0 for LOW (selects the radio IC), or 2 for floating.

void system_sleep ( void )

Enters sleep mode.

Note: This function is used by the scheduler and should not be called anywhere else.

void system_sleep_low_power ( void )

Enters low-power sleep mode.

Note: This function is used by the scheduler and should not be called anywhere else.

void system_try_select_rf_path ( rf_path_t path )

Selects the requested RF path.

Note: What can actually be done depends on the RF switches available on the board.

Parameters

path	The path to select. This can be PATH_RX, PATH_TX_RFO, PATH_TX_PA, or PATH_NONE.
