This brings in the new ADC api for STM32 parts.
Update to new standardized ADC apis.
Drops pointless channel definitions, uses common names for common functions.
No functional changes.
Based on work in: https://github.com/libopencm3/libopencm3-examples/pull/130
Update documentation and comments in code to reflect reality.
Ensure that GPIO pin output speed is actually set, to ensure that 48Mhz sysclk
output is functional.
Actually set AF, instead of relying on reset values.
Replace the systick code, the core of this example, with some code that has
less traps and surprises. Instead of trying to get a direct interrupt x times
per second, and reguarly running into problems with the 24 bit counter limit,
use a method that triggers an interrupt every x ms instead. Tested MCO and
blink rates with a logic analyser, properly verified working now :)
These should have been moved over when the library was initial split.
Even if we eventually drop any attempt at flash support, at least have all the
files here.
Correctly migrate stm32f103_usb_driver to st_usbfs_v1_driver instead of the
f107 driver.

Be specifically careful with the usb examples. There is likely some
breakage to be expected, not sure I updated all the drivers to the
correct types for the respective chips.
As found in 6f2b39c1be6a8b9531264d92138dc2629d51cfa0, you can't just register a
control callback by itself, you can only register them in the set config
callback, (or, at least, _after_ set config has been done.
This has been compile tested only for the extra examples that were found to
have this failing pattern.
This has been broken since f87170e when set config started clearing control
handlers to be re-registered by different configurations.
Fix this example to use a set config callback to setup control transfer
callbacks, just like CDC-ACM demos. With this fix, this demo works with
dfu-tool 0.8

This example muxes two pins as GPIO and enables one GPIO (logical
high). The other GPIO is then read in the main loop. One can use
a jumper to bridge the two GPIOs to see that also reading succeeds.
The UART's baud rate is calculated using the current clock
configuration from the clock module. This example makes use
of the standard C library and writes the characters to the
UART in blocking mode.
This example takes advantage of the big Flash memory space and
uses the standard library functions printf, and fgets to
implement a simple interactive application.
This example is just using buffers and built in alpha overlay
functionality to animate a dmond floating on a checker board. After
initializing of the frame buffers only 7 registers are being modified to
implement the animation.
This version is the ASCII one but uses the LCD display
that is attached to the board for a more colorful result.
This example also zooms into a more "interesting" place in the set so
the display stays interesting during the full 100 generations.
Remove the ISR function and remains of the hack in lcd-spi.c and
convert console.c to use the LOC3 system reset code rather than
the hack which only works on the F4 as it turns out.
Now that I know a bit more about how SPI is working on the STM32F4
I removed the egregious hack and replaced it with some cleaner code
for driving the LCD. On the positive side it gets a faster update
rate on the screen.
