sahilmgandhi | 18:6a4db94011d3 | 13 | ============================================================================== |
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 | 123 | =============================================================================== |
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. |
