Function Documentation

ri_power_enter_bootloader()

void ri_power_enter_bootloader

(

void

)

Enter bootloader.

This function attempts to enter bootloader. It's main purpose is to provide a wireless recovery mechanism on fatal error.

Warning

Behaviour is undefined if bootloader is not onboard.

ri_power_regulators_enable()

rd_status_t ri_power_regulators_enable

(

const ri_power_regulators_t

regulators

)

Enable given regulators.

The implementation must work regardless of software radio state, i.e. on S132 on nRF52 the function must check if softdevice is running and call softdevice wrapper to DC/DC if it is and write registers directly if SD is not running.

Parameters

[in]

regulators

binary flags of regulators to enable.

Returns

RD_SUCCESS on success, error code from stack in case of a error.

ri_power_reset()

void ri_power_reset

(

void

)

Reset IC.

This function attempts to reset and restart the program as closely as possible to a power cycle.

Warning

This functions affects only the CPU, any peripheral sensors must be reset separately.

Some registers might retain their values across soft resets.
