sahilmgandhi 18:6a4db94011d3 14 [..]
sahilmgandhi 18:6a4db94011d3 15 The common HAL driver contains a set of generic and common APIs that can be
sahilmgandhi 18:6a4db94011d3 16 used by the PPP peripheral drivers and the user to start using the HAL.
sahilmgandhi 18:6a4db94011d3 17 [..]
sahilmgandhi 18:6a4db94011d3 18 The HAL contains two APIs' categories:
sahilmgandhi 18:6a4db94011d3 19 (+) Common HAL APIs
sahilmgandhi 18:6a4db94011d3 20 (+) Services HAL APIs

sahilmgandhi 18:6a4db94011d3 124 [..] This section provides functions allowing to:
sahilmgandhi 18:6a4db94011d3 125 (+) Initializes the Flash interface the NVIC allocation and initial clock
sahilmgandhi 18:6a4db94011d3 126 configuration. It initializes the systick also when timeout is needed
sahilmgandhi 18:6a4db94011d3 127 and the backup domain when enabled.
sahilmgandhi 18:6a4db94011d3 128 (+) de-Initializes common part of the HAL
sahilmgandhi 18:6a4db94011d3 129 (+) Configure The time base source to have 1ms time base with a dedicated
sahilmgandhi 18:6a4db94011d3 130 Tick interrupt priority.
sahilmgandhi 18:6a4db94011d3 131 (++) Systick timer is used by default as source of time base, but user
sahilmgandhi 18:6a4db94011d3 132 can eventually implement his proper time base source (a general purpose
sahilmgandhi 18:6a4db94011d3 133 timer for example or other time source), keeping in mind that Time base
sahilmgandhi 18:6a4db94011d3 134 duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
sahilmgandhi 18:6a4db94011d3 135 handled in milliseconds basis.
sahilmgandhi 18:6a4db94011d3 136 (++) Time base configuration function (HAL_InitTick ()) is called automatically
sahilmgandhi 18:6a4db94011d3 137 at the beginning of the program after reset by HAL_Init() or at any time
sahilmgandhi 18:6a4db94011d3 138 when clock is configured, by HAL_RCC_ClockConfig().
sahilmgandhi 18:6a4db94011d3 139 (++) Source of time base is configured to generate interrupts at regular
sahilmgandhi 18:6a4db94011d3 140 time intervals. Care must be taken if HAL_Delay() is called from a
sahilmgandhi 18:6a4db94011d3 141 peripheral ISR process, the Tick interrupt line must have higher priority
sahilmgandhi 18:6a4db94011d3 142 (numerically lower) than the peripheral interrupt. Otherwise the caller
sahilmgandhi 18:6a4db94011d3 143 ISR process will be blocked.
sahilmgandhi 18:6a4db94011d3 144 (++) functions affecting time base configurations are declared as __weak
sahilmgandhi 18:6a4db94011d3 145 to make override possible in case of other implementations in user file.
