phungductung 0:e87aa4c49e95 14 [..]
phungductung 0:e87aa4c49e95 15 The common HAL driver contains a set of generic and common APIs that can be
phungductung 0:e87aa4c49e95 16 used by the PPP peripheral drivers and the user to start using the HAL.
phungductung 0:e87aa4c49e95 17 [..]
phungductung 0:e87aa4c49e95 18 The HAL contains two APIs' categories:
phungductung 0:e87aa4c49e95 19 (+) Common HAL APIs
phungductung 0:e87aa4c49e95 20 (+) Services HAL APIs

phungductung 0:e87aa4c49e95 109 ##### Initialization and de-initialization functions #####
phungductung 0:e87aa4c49e95 110 ===============================================================================
phungductung 0:e87aa4c49e95 111 [..] This section provides functions allowing to:
phungductung 0:e87aa4c49e95 112 (+) Initializes the Flash interface the NVIC allocation and initial clock
phungductung 0:e87aa4c49e95 113 configuration. It initializes the systick also when timeout is needed
phungductung 0:e87aa4c49e95 114 and the backup domain when enabled.
phungductung 0:e87aa4c49e95 115 (+) de-Initializes common part of the HAL
phungductung 0:e87aa4c49e95 116 (+) Configure The time base source to have 1ms time base with a dedicated
phungductung 0:e87aa4c49e95 117 Tick interrupt priority.
phungductung 0:e87aa4c49e95 118 (++) Systick timer is used by default as source of time base, but user
phungductung 0:e87aa4c49e95 119 can eventually implement his proper time base source (a general purpose
phungductung 0:e87aa4c49e95 120 timer for example or other time source), keeping in mind that Time base
phungductung 0:e87aa4c49e95 121 duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
phungductung 0:e87aa4c49e95 122 handled in milliseconds basis.
phungductung 0:e87aa4c49e95 123 (++) Time base configuration function (HAL_InitTick ()) is called automatically
phungductung 0:e87aa4c49e95 124 at the beginning of the program after reset by HAL_Init() or at any time
phungductung 0:e87aa4c49e95 125 when clock is configured, by HAL_RCC_ClockConfig().
phungductung 0:e87aa4c49e95 126 (++) Source of time base is configured to generate interrupts at regular
phungductung 0:e87aa4c49e95 127 time intervals. Care must be taken if HAL_Delay() is called from a
phungductung 0:e87aa4c49e95 128 peripheral ISR process, the Tick interrupt line must have higher priority
phungductung 0:e87aa4c49e95 129 (numerically lower) than the peripheral interrupt. Otherwise the caller
phungductung 0:e87aa4c49e95 130 ISR process will be blocked.
phungductung 0:e87aa4c49e95 131 (++) functions affecting time base configurations are declared as __weak
phungductung 0:e87aa4c49e95 132 to make override possible in case of other implementations in user file.
