| // I2C to USB Adapter using Arduino | |

| /** | |
| * This sketch can get loaded onto an Arduino to use it as USB to I2C Adapter. | |
| * It uses the Wire library. So take a look at the documentation of the Wire | |
| * libarary about the pins being used as SDA/SCL. For most Arduino boards this | |
| * will be analog input pin 4 for SDA and analog input pin 5 for SCL. | |

| * On the USB side the default serial link of the Arduino is used. A protocol |

This is a collection of code snippets for various features on the STM8S family microcontrollers (specifically the STM8S003F3). These are written against the STM8S/A SPL headers and compiled using SDCC.
Some of this controller's functions aren't particularly intuitive to program, so I'm dumping samples for future reference here. These are based on the STM8S documentation:

###Setting up Pi Zero OTG - The quick way (No USB keyboard, mouse, HDMI monitor needed)
More details - http://blog.gbaman.info/?p=791
For this method, alongside your Pi Zero, MicroUSB cable and MicroSD card, only an additional computer is required, which can be running Windows (with Bonjour, iTunes or Quicktime installed), Mac OS or Linux (with Avahi Daemon installed, for example Ubuntu has it built in).
1. Flash Raspbian Jessie full or Raspbian Jessie Lite onto the SD card.
2. Once Raspbian is flashed, open up the boot partition (in Windows Explorer, Finder etc) and add to the bottom of the config.txt file dtoverlay=dwc2 on a new line, then save the file.
3. If using a recent release of Jessie (Dec 2016 onwards), then create a new file simply called ssh in the SD card as well. By default SSH is
