| 24 | The common HAL driver contains a set of generic and common APIs that can be |
||
| 25 | used by the PPP peripheral drivers and the user to start using the HAL. |
||
| 26 | [..] |
||
| 27 | The HAL contains two APIs' categories: |

| 28 | (+) Common HAL APIs |
||
| 29 | (+) Services HAL APIs |

||
| 102 | and the backup domain when enabled. |
||
| 103 | (+) de-Initializes common part of the HAL. |
||
| 104 | (+) Configure The time base source to have 1ms time base with a dedicated |
||
| 105 | Tick interrupt priority. |
||
| 106 | (++) SysTick timer is used by default as source of time base, but user |
||
| 107 | can eventually implement his proper time base source (a general purpose |
||
| 108 | timer for example or other time source), keeping in mind that Time base |
||
| 109 | duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and |
||
| 110 | handled in milliseconds basis. |
||
| 111 | (++) Time base configuration function (HAL_InitTick ()) is called automatically |
||
| 112 | at the beginning of the program after reset by HAL_Init() or at any time |
||
| 113 | when clock is configured, by HAL_RCC_ClockConfig(). |
||
| 114 | (++) Source of time base is configured to generate interrupts at regular |
||
| 115 | time intervals. Care must be taken if HAL_Delay() is called from a |
||
| 116 | peripheral ISR process, the Tick interrupt line must have higher priority |
||
| 117 | (numerically lower) than the peripheral interrupt. Otherwise the caller |
||
| 118 | ISR process will be blocked. |
||
| 119 | (++) functions affecting time base configurations are declared as __weak |
