* @brief init() and board routines. |
|||
* |
|||
* This file is mostly interesting for the init() function, which |
|||
* configures Flash, the core clocks, and a variety of other available |
|||
* peripherals on the board so the rest of Wirish doesn't have to turn |
|||
* things on before using them. |
|||
* |
|||
* Prior to returning, init() calls boardInit(), which allows boards |
|||
* to perform any initialization they need to. This file includes a |
|||
* weak no-op definition of boardInit(), so boards that don't need any |
|||
* special initialization don't have to define their own. |
|||
* |
|||
* How init() works is chip-specific. See the boards_setup.cpp files |
|||
* under e.g. wirish/stm32f1/, wirish/stmf32f2 for the details, but be |
|||
* advised: their contents are unstable, and can/will change without |
|||
* notice. |
