Makefile Setup

1. Get the code

• Clone the repository (using git on the command line, or Sourcetree, etc.)
• Add to .bash_profile (Mac) or .bashrc (Linux / Cygwin)

  export KODUINO_DIR=<koduino_location>/stm32

2. Toolchain setup

If you have the Arduino IDE 1.6.1

• Add to .bash_profile (Mac) or .bashrc (Linux / Cygwin)

  export PATH=$PATH:/Applications/Arduino.app/Contents/Resources/Java/hardware/tools/gcc-arm-none-eabi-4.8.3-2014q1/bin

...otherwise,

• Download gcc-arm-embedded 4.8 2014 q1 for your platform
• Add to .bash_profile (Mac) or .bashrc (Linux / Cygwin)

  export PATH=$PATH:<directory_you_extracted>/bin

In either case, test that it worked by running

arm-none-eabi-gcc --version

from a new terminal window.

3. Write your first program

Makefile template

In a new directory, create a file called Makefile with the following contents.

VARIANT = f37x
HSE_VALUE = 16000000UL
UPLOAD_METHOD = SERIAL
UPLOAD_BAUD = 230400
# Put libraries you want to use here
LIBRARIES = SPI Wire

include $(KODUINO_DIR)/project.mk

Sketch template

Create another file called Blink.cpp with the following contents. (This is the Blink example from the Digital output section.)

#include <Arduino.h>

// Change to whatever pin an LED is connected to
const int led = PC13;

void setup() {
  pinMode(led, OUTPUT);
}

void loop() {
  digitalWrite(led, TOGGLE);
  delay(1000);
}

4. Upload the code

Run make in this directory. Hint: Sublime Text 3 with the "Make" build system is very convenient for this.
