Description:
Example to interact with KEY button and user external button connected to PA1.
For KEY button pull-up resistor is active, board schematic does not show any pull-up or pull-down resistor.
Results: Example working as expected.
BlackPill PWM example
Description:
PWM example using PB0 - Timer3 - Channel 3
Create default configuration for the example.
Controlling_RGB_LED
Description: Controlling a RGB LED on NuttX for Black Pill board [STM32F411]
Note: Example currently not working as expected.
This patch allows user to simply select which GPIOs he wants to use
and access them via /dev/gpio_a0 or similar device with standard
gpio driver.
By default gpio names match pin names printed on the board. So when
enabling A3 pin, it will show as /dev/gpio_a3 in runtime. This name
can be changed in kconfig.
User can also select pin function (input, output, interrupt) as well
as standard pin settings like, pull up/down, output type
pushpull/open drain etc.
All pins that are exposed via boards goldpins are listed in Kconfig.
Extra pins that are supported by chiip but are not exposed for easy
usage are not listed.
To have this nice Kconfig configuration and for things to be easily
debugable/understandable it requires code to have big Kconfig and
header file with all possible definitions
Because of file sizes I decided to split gpio related kconfig and
header into separate files. Otherwise it would really make original
files hard to read and find anything.

The class device only handles descriptor information specific to the class,
and shared descriptor information is passed through parameters and
handled by the composite driver.

* Bind smartfs0 to LUN 0 instead of mmcsd0
* Use USB composite code from similar boards
* Pull in CDC/ACM code as well
boards/stm32f411-minimum: composite: style refactor
* Unalign `int strbase = ` text, use single spaces
* Rename `int n` to `int dev_idx` like in newer `_composite.c` board code
* Add composite defconfig with CDC/ACM and MSC for build-testing
* OTG_FS_VBUS, OTG_FS_ID conflict with USART1. These are not
connected to USB-C in any WeAct Studio MiniF4 board revisions.
* PC9 PWRON & PD5 OVER do not exist on UFQFPN48.
