Piotr Esden-Tempski 976720c355 Updated libopencm3 to current master. Made all examples compile again.

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.

README

This is functionally identical to the "button-irq-printf" example, but has been modified to use some low power features.

There is a 115200@8n1 console on PA2, which prints a tick count every second, and when the user push button is pressed, the time it is held down for is timed (in milliseconds)

Instead of free running timers and busy loops, this version uses the RTC module and attempts to sleep as much as possible, including while the button is pressed.

Status

Only very basic power savings are done!

Current consumption, led off/on, 16Mhz HSI: 2.7mA/5.4mA Current consumption, led off/on, 4Mhz HSI: 1.4mA/?.?mA Current consumption, led off/on, 4Mhz MSI: 0.9mA/?.?mA
