The STM libraries provide access to STM specific hardware such as GPIO, DMA, UARTs, etc. It has a driver API but which is not talking to the CMSIS compliant drivers( ST). This could be useful in some library where it is necessary to : read the state of an gpio input ( get a state) set a gpio output state ( launch an action) get an interruption/ e.


The GPIO controller driver directly accesses the hardware registers of the GPIO controller device. Add an < examples> section with the. Gpio driver cmsis.


In the code below, a general GPIO typedef is declared for the group of GPIO reregisters. For all remaining bits that are not activated in bitValue ( value ' 0' ) will not be effected by this function. For the first pair, the relative position would be zero. The ARM: : CMSIS Pack contains an example of a Software Pack that contains device support, board support and software components. Gpio driver cmsis.

It works fine when I use printf function. Unfortunately when I want to use Ethernet library from cmsis this command " printf" hangs my mcu and when I change printf with USART_ SendData( USART1, ch) ; my mcu works fine. Also I want to find out how CMSIS configures the processor at start up, e. I want to build a new project, using the outstanding CMSIS library, because this is a complete driver library for the MCU peripherals. And doesn' t work out of box without modification.
