discovery-stm32f072: Blink the LEDs
This just makes the LEDs blink continually, because I have a
development board sitting on my desk and I like to see it doing
something.
You can still force the GPIOs on and off using the tool in
extra/usb_gpio/.
BUG=none
BRANCH=none
TEST=make buildall
Try it:
sudo make BOARD=discovery-stm32f072 flash
The LEDs blink.
Force them on and off with:
cd extra/usb_gpio
make
./usb_gpio write -1 0
./usb_gpio write 0 -1
./usb_gpio write 2 0
./usb_gpio write 4 2
To resume blinking, use
./usb_gpio write 0 0
