Function Documentation

void hw_timer_arm

(

uint32

val

)

Parameters

uint32

val : Timing In autoload mode, range : 50 ~ 0x7fffff In non-autoload mode, range : 10 ~ 0x7fffff

Returns

null

void hw_timer_init

(

uint8

req

)

Initialize the hardware ISR timer.

Parameters

uint8

req : 0, not autoload; 1, autoload mode.
