bsp_get_timer_register()

uint32_t bsp_get_timer_register

(

void

)

Returns the time difference from last call of bsp_clear_timer_register to this bsp_get_timer_register. It handles overflow.

Return values

32-bit

time elapsed since last call to bsp_clear_timer_register

bsp_clear_timer_register()

void bsp_clear_timer_register

(

void

)
