Programming the Nucleo STM32L476

I have found it a bit confusing programming the Nucleo in the IDE's suggested from the site. I am use to the Arduino IDE as it is fairly easy to use. So, I found a way to program the Nucleo with the Arduino IDE. This was created by Srihari Koripalli who deserves all the credit for this.

Below is how it is done:

Open the Arduino IDE
Go to the "File" menu
Go to "Preferences"
Under "Additional Boards Manager URLs" enter the link below:

https://raw.githubusercontent.com/stm32duino/BoardManagerFiles/master/STM32/package_stm_index.json

Go to "Tools" menu, Click on "Board" then Click on "Boards Manager"

Scroll down until you find the "STM32 Core" Package by ST-Microelectronics and install it. This will take a bit of time to install.

That is it for this part

Next download the PinMap for the Nucleo Board to the Arduino IDE

https://github.com/sriksh9/Nucleo-PinMapping-for-Arduino

The PinMap is technically for the f401 board, but is the same for the L476 and does work

Put the downloaded folder into the Arduino Library Folder (My directory is "C:\Program Files (X86)\Arduino\libraries")

Next you will have to change the Board in the IDE to the correct Nucleo board by going to "Tools" - "Board" - Select the correct board type "Nucleo-64"

Then select "Board Part Number" - Select "Nucleo L476RG" - Finally select the correct "Port" the board is attached to

This quick program blinks a light from "Pin D2" on the board (PinMap 1)

#include 
int a = pinMap(1); //pinMap(Mapped Pin) - for mapped pin refer the attacted image
void setup()
{
  pinMode(a, OUTPUT);
}
void loop()
{
  digitalWrite(a, 1);
  delay(500);
  digitalWrite(a, 0);
  delay(500);

}

I want to thank Srihari Koripalli for coming up with this!!

I hope this helps others with the programming of the board. It works great!!
