[..]
|
|
The common HAL driver contains a set of generic and common APIs that can be
|
|
used by the PPP peripheral drivers and the user to start using the HAL.
|
|
[..]
|
|
The HAL contains two APIs categories:
|
|
(+) Common HAL APIs
|
|
(+) Services HAL APIs

##### HAL Initialization and Configuration functions #####

|
[..] This section provides functions allowing to:
|
|
(+) Initialize the Flash interface the NVIC allocation and initial time base
|
|
clock configuration.
|
|
(+) De-initialize common part of the HAL.
|
|
(+) Configure the time base source to have 1ms time base with a dedicated
|
|
Tick interrupt priority.
|
|
(++) SysTick timer is used by default as source of time base, but user
|
|
can eventually implement his proper time base source (a general purpose
|
|
timer for example or other time source), keeping in mind that Time base
|
|
duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
|
|
handled in milliseconds basis.
|
|
(++) Time base configuration function (HAL_InitTick ()) is called automatically
|
|
at the beginning of the program after reset by HAL_Init() or at any time
|
|
when clock is configured, by HAL_RCC_ClockConfig().
|
|
(++) Source of time base is configured to generate interrupts at regular
|
|
time intervals. Care must be taken if HAL_Delay() is called from a
|
|
peripheral ISR process, the Tick interrupt line must have higher priority
|
|
(numerically lower) than the peripheral interrupt. Otherwise the caller
|
|
ISR process will be blocked.
|
|
(++) functions affecting time base configurations are declared as __weak
|
|
to make override possible in case of other implementations in user file.
