Function Documentation

get_board_serial()

void get_board_serial

(

char

out[13]

)

Gets the serial number of the board vll_wsk_01**.

Parameters

out	Out buffer for the returned string.

hal_core1_entry()

(

void(*

entry )(void)

)

Parameters

ms_timeout

How many milliseconds of timeout before the watchdog resets the chip.

hal_sleep_ms()

void hal_sleep_ms

(

uint32_t

ms
