Hi guys

I will give a quick run down so you can gauge my ability, as well as how you can help - which I would very much appreciate

equipment I am using:

Nucleo F030R8ST-Link v2STM32CubeMXKeil uVision5

I started using the Nucleo recently, and it has been a big step up . In the past I used the Arduino comfortably. I made an app for the iphone to control LED lights connected to a Teensy(Arduino adaptation in simple) via bluetooth. I also touched upon the ESP8266 and hosted a webpage.

Since stepping up to the Nucleo I have struggled. I use the STM32CubeMX and downland to Keil. I have done a basic �Hello World� program which is to light up LD2 on my Nucleo. Success (link I used-

http://www.instructables.com/id/STM32F103-Blink-LED/).

However, I feel stuck and unsure of what to do now. I do not know the commands to do things. When the code was downloaded to Keil there is a line that reads:

HAL_GPIO_TogglePin(LD2_GPIO_Port,LD2_Pin);

My understanding is this sets off the light when the button is pressed. However, how do I know what all the other commands are?

If I want to turn on the light, what do I do. and to turn off?If I wanted turn on for 2 seconds, turn off for 1, how would I do that?

Then to advance, if i wanted to light up an external led on a breadboard, how would I go about that? and finally are there any projects you recommend I do to get stuck in?

Many thanks in advance, and I will reply as soon as I can

If you want to use the Cube HAL library, read its documentation

Examples under the Cube F0 tree that toggles LED, one on board, but could be changed to use pin on Arduino header, etc

Hi JW,

thank you, however, do you know any shortened guides, or resources which focus on using the LED's?

Hi, I dont have the following file path on my computer.

also, I dont want to use an Arduino in any form, just Nucleo

The file is part of the CubeF0 package, you can either unpack it directly, or use CubeMX and have that install it under the repository directory.

The pin headers, including the Arduino header, provide an arbitrary point to which to connect a breadboard or LEDs.

I would suspect YouTube to be a good source of videos, tutorials and the like.

thanks for the help, this is what i need...for now.

I have looked around for youtube videos, and maybe I am looking in the wrong places, but I did not find them so useful, or not aimed at the f030r8.

The file you said to download is a great starting point, and I am sure when I dig into it further I will begin to get a greater understanding

thank you!
