Nucleo-F303 blink example

When I first powered up my board it ran a program that would flash the red, green, and blue LEDs at different rates upon a button press.

I would like to examine the source but I cannot find it in the CubeF3 projects. Is it there? I thought it would be GPIO_EXTI but that does not seem to be it.

Which Nucleo has 3 user-controllable LEDs? Nucleo-F303 comes in all 3 formats, but AFAIK all of them have only one single LED actually connected to the mcu.

The factory-programmed firmware is always in [CubeXX]/Projects/[Board]/Demonstrations directory. For Nuclei, it's confusingly called Adafruit something, but read the accompanying Release_Notes.html, the blinky *is* there.

Nucleo-144 boards have 3 user LEDs - green, blue and red.

Hi JW,

Thanks for posting.

I have a Nucleo-F303ZE, the number is fresh in my mind as I just saw it while checking the status of SB119 and SB120. It came with a program that flashed the green LED 4 times a second, pushing the button would cause it to flash the red once a second, or the blue every two seconds.

I will go search per your directions.

Thanks,

John.

It looks like all Nucleo packages are not created equally. The only demonstration code that came with this device's examples is a joystick program.
