Installing vbit py

vbit-py teletext inserter

To run vbit.py you need:

• Raspberry Pi
• vbit teletext inserter
• PAL video source
• Teletext capable TV

vbit-py is a driver for the vbit teletext inserter hardware.

These instructions use vbit2 to provide a teletext stream.

Suitable vbit hardware has been manufactured by Peter Kwan and Nat Dane

Installing vbit.py

The Raspberry Pi should be running Raspbian, preferably with all the software updated. Go into Preferences->Raspberry Pi Configuration and enable SPI and I2C.

Install vbit2

Follow the instructions for installing vbit2. The section about getting vbit2 to auto start can be ignored.
