I2C Peripheral Mode

We highly encourage everyone to use our new Python package which is packed with features. This library is still supported, but is not recommended for new design.

This example demonstrates how to use Binho Nova as an I2C Peripheral device, with a device address of 0xA0 and operating in USEPTR mode of emulation.
