The project build is now automated by using either **Arduino-Makefile** or **platformio** (your choice), you can still use **Arduino IDE** as well.

The default build is for Arduino Mega2560, but this can be ported to other boards.  

**'PLEASE NOTE:'** This repo contains submodules, so for the first time cloning the repo you can do it like this: **'git clone --recursive https://github.com/lcapossio/fresca.git'**, or if you already cloned 
you have to initialize the submodules: **'git submodule update --init --recursive'**. Also each time you pull, you have to pull recursively, in case there is an update for the submodules: **'git pull --recurse-submodules'**  

Using **Arduino IDE**:  

* Add all the libraries under **'arduino/lib'**
* The main sketch is **'arduino/src/fresca.ino'**
* Compile and upload the sketch

Using **Arduino-Makefile**:  

* **'cd'** to the **'arduino/src'** folder  
* run **'make ARDUINO_DIR=your/arduino/install/path'**  

Using **platformio**:  

* **'cd'** to the **'arduino'** folder  
* run **'platformio run'**  

### Configuration/Pinout
The configuration/pinout for the code can be modified easily in **'arduino/lib/fresca/fresca_pinout.h'**. Look at the commented description of each line to know what they are used for.

Keypad is connected to an analog pin.
Each sensor is connected to a single digital I/O.
7-Segment displays CLK pins are connected to a single arduino digital pin.
