debounced_button_irq_handler()

void debounced_button_irq_handler

(

GPT_TypeDef *

timer

)

Interrupt handler of the button debounce timer.

Connected by the board to the timer set in its button configuration.

Parameters

timer

Debounce timer.

rc10k_cyc_to_milli_ticks()

uint32_t rc10k_cyc_to_milli_ticks

(

uint32_t

rc10k_cyc

)

Convert RC10K cycles to RTC milli-ticks.

Parameters

rc10k_cyc

Number of RC10K cycles.

Returns

Duration in thousandths of an RTC tick.

rc10k_get_freq_hz()

uint32_t rc10k_get_freq_hz

(

void

)

Get the calibrated RC10K frequency.

Returns

Frequency in Hz, nominal 10 kHz if no calibration is available.

rc10k_init()

void rc10k_init

(

void

)

Initialize the RC10K low-power oscillator calibration.

Calibrates the oscillator against the 48 MHz crystal now and then every 15 seconds.
