| elmot | 1:d0dfbce63a89 | 14 | [..] |
| elmot | 1:d0dfbce63a89 | 15 | The common HAL driver contains a set of generic and common APIs that can be |
| elmot | 1:d0dfbce63a89 | 16 | used by the PPP peripheral drivers and the user to start using the HAL. |
| elmot | 1:d0dfbce63a89 | 17 | [..] |
| elmot | 1:d0dfbce63a89 | 18 | The HAL contains two APIs' categories: |
| elmot | 1:d0dfbce63a89 | 19 | (+) Common HAL APIs |
| elmot | 1:d0dfbce63a89 | 20 | (+) Services HAL APIs |

| elmot | 1:d0dfbce63a89 | 116 | =============================================================================== |
| elmot | 1:d0dfbce63a89 | 117 | [..] This section provides functions allowing to: |
| elmot | 1:d0dfbce63a89 | 118 | (+) Initialize the Flash interface the NVIC allocation and initial time base |
| elmot | 1:d0dfbce63a89 | 119 | clock configuration. |
| elmot | 1:d0dfbce63a89 | 120 | (+) De-initialize common part of the HAL. |
| elmot | 1:d0dfbce63a89 | 121 | (+) Configure the time base source to have 1ms time base with a dedicated |
| elmot | 1:d0dfbce63a89 | 122 | Tick interrupt priority. |
| elmot | 1:d0dfbce63a89 | 123 | (++) SysTick timer is used by default as source of time base, but user |
| elmot | 1:d0dfbce63a89 | 124 | can eventually implement his proper time base source (a general purpose |
| elmot | 1:d0dfbce63a89 | 125 | timer for example or other time source), keeping in mind that Time base |
| elmot | 1:d0dfbce63a89 | 126 | duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and |
| elmot | 1:d0dfbce63a89 | 127 | handled in milliseconds basis. |
| elmot | 1:d0dfbce63a89 | 128 | (++) Time base configuration function (HAL_InitTick ()) is called automatically |
| elmot | 1:d0dfbce63a89 | 129 | at the beginning of the program after reset by HAL_Init() or at any time |
| elmot | 1:d0dfbce63a89 | 130 | when clock is configured, by HAL_RCC_ClockConfig(). |
| elmot | 1:d0dfbce63a89 | 131 | (++) Source of time base is configured to generate interrupts at regular |
| elmot | 1:d0dfbce63a89 | 132 | time intervals. Care must be taken if HAL_Delay() is called from a |
| elmot | 1:d0dfbce63a89 | 133 | peripheral ISR process, the Tick interrupt line must have higher priority |
| elmot | 1:d0dfbce63a89 | 134 | (numerically lower) than the peripheral interrupt. Otherwise the caller |
| elmot | 1:d0dfbce63a89 | 135 | ISR process will be blocked. |
| elmot | 1:d0dfbce63a89 | 136 | (++) functions affecting time base configurations are declared as __weak |
| elmot | 1:d0dfbce63a89 | 137 | to make override possible in case of other implementations in user file. |
