##Hatalogico Libraries for the Hatalogico Raspberry Pi Hat

###Cloning This Repo When cloning, it is crucial that you use the --recursive switch in order to fetch the Adafruit submodules.

All the python files required to drive the I2C chips on the Hatalogico were written and are maintained by Adafruit Industries. I have simply included them as submodules and written a few examples using them.

Before using these files, you need to setup your Pi for GPIO and I2C (note the Pi 2 has a slightly different method for the latter).

Setting up the I2C

Setting up the GPIO

##Installing The RPi2 is slightly different but I recommend you 'apt-get' the following packages on both platforms:

sudo apt-get update -y
sudo apt-get install -y python-dev python-rpi.gpio python-smbus
sudo apt-get install -y i2c-tools libi2c-dev

You can copy and paste all 3 lines into your terminal and they will run one after the other (synchronously).

You will need to add the I2C tools to both versions:
sudo nano /etc/modules

Scroll to the bottom and add:
i2c-dev

####For RPi B+ and older only: Also add a new line underneath 'i2c-dev':
i2c-bcm2708

Crtl-X to close, pressing Y to save the changes (overwrite with the same name by pressing enter)

####For the RPi B+ or older you will need to update the blacklist file:
sudo nano /etc/modprobe.d/raspi-blacklist.conf

Update it to read:
#blacklist spi-bcm2708
#blacklist i2c-bcm2708

After all of this, it's wise to do a little housekeeping (perhaps even removing some unused libraries):
sudo apt-get -y purge wolfram-engine
sudo apt-get -y autoremove
sudo apt-get -y clean
sudo apt-get -y update
sudo apt-get -y dist-upgrade

#I2C Addresses (on the prototype model)

1. 16 Channel PWM: 0x70
2. 4 Channel ADC #1: 0x49
3. 4 Channel ADC #2: 0x48
4. Single Channel DAC #1: 0x60
5. Single Channel DAC #2: 0x61

###Big thanks to Adafruit without whom the Hatalogico would just be a mug coaster.
