This is a simple I2C bus scanning tool to scan for and report any
responding devices. All I2C addresses are checked from 1 to 127.
Results are reported on the UART0 serial port.
Configuration:
Attach any I2C devices to your I2C bus. Be sure and enable
the bus pull-up resistors.
Attach a terminal to UART0 (9600, 8N1) for viewing the
results.
