| saloutos | 0:083111ae2a11 | 15 | The common HAL driver contains a set of generic and common APIs that can be |
| saloutos | 0:083111ae2a11 | 16 | used by the PPP peripheral drivers and the user to start using the HAL. |
| saloutos | 0:083111ae2a11 | 17 | [..] |
| saloutos | 0:083111ae2a11 | 18 | The HAL contains two APIs' categories: |

| saloutos | 0:083111ae2a11 | 111 | [..] This section provides functions allowing to: |
| saloutos | 0:083111ae2a11 | 112 | (+) Initializes the Flash interface the NVIC allocation and initial clock |
| saloutos | 0:083111ae2a11 | 113 | configuration. It initializes the systick also when timeout is needed |
| saloutos | 0:083111ae2a11 | 114 | and the backup domain when enabled. |
| saloutos | 0:083111ae2a11 | 115 | (+) de-Initializes common part of the HAL |
| saloutos | 0:083111ae2a11 | 116 | (+) Configure The time base source to have 1ms time base with a dedicated |
| saloutos | 0:083111ae2a11 | 117 | Tick interrupt priority. |
| saloutos | 0:083111ae2a11 | 118 | (++) Systick timer is used by default as source of time base, but user |
| saloutos | 0:083111ae2a11 | 119 | can eventually implement his proper time base source (a general purpose |
| saloutos | 0:083111ae2a11 | 120 | timer for example or other time source), keeping in mind that Time base |
| saloutos | 0:083111ae2a11 | 121 | duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and |
| saloutos | 0:083111ae2a11 | 122 | handled in milliseconds basis. |
| saloutos | 0:083111ae2a11 | 123 | (++) Time base configuration function (HAL_InitTick ()) is called automatically |
| saloutos | 0:083111ae2a11 | 124 | at the beginning of the program after reset by HAL_Init() or at any time |
| saloutos | 0:083111ae2a11 | 125 | when clock is configured, by HAL_RCC_ClockConfig(). |
| saloutos | 0:083111ae2a11 | 126 | (++) Source of time base is configured to generate interrupts at regular |
| saloutos | 0:083111ae2a11 | 127 | time intervals. Care must be taken if HAL_Delay() is called from a |
| saloutos | 0:083111ae2a11 | 128 | peripheral ISR process, the Tick interrupt line must have higher priority |
| saloutos | 0:083111ae2a11 | 129 | (numerically lower) than the peripheral interrupt. Otherwise the caller |
| saloutos | 0:083111ae2a11 | 130 | ISR process will be blocked. |
| saloutos | 0:083111ae2a11 | 131 | (++) functions affecting time base configurations are declared as __weak |
| saloutos | 0:083111ae2a11 | 132 | to make override possible in case of other implementations in user file. |
