vsf_driver_init()

bool vsf_driver_init

(

void

)

common hal drivers

Note

initialize device driver

Parameters

none

Return values

true	initialization succeeded.
false	initialization failed

initialise interrupt controller;

vsf_driver_poll()

bool vsf_driver_poll

(

void

)

driver polling service for f1c100s

Parameters

none

Return values

true	it is safe to enter sleep mode
false	polling work is on going, please keep calling the function

Note

example about how to put poll functions for each instance of peripherals ! even if the function doesn't exist, the compilation would not be ! affected as long as the corresponding macro ! VSF_HAL_DRV_CFG_XXXX_POLL_MODE_EN is set to DISABLED, i.e. 0
