/* UsiSerial by email@example.com * * UsiSerial is a simple wrapper around the code from AVR307 so that Arduino can use USI to implement a hardware serial port * * The USI class works almost exactly like HardwareSerial * So you can use print and println and other functions like that * * PORTB0 is DI, thus it is RX * PORTB1 is DO, thus it is TX * default baud rate is 19200, which can only be changed in USI_UART_config.h * only some baud rates will work, depending on CPU frequency * buffers are small to save memory, since this library is designed for ATtiny * testing was done using a 16 MHz Trinket * * Important note: requires Timer1 and PCINT to be occupied * Copyright (c) 2013 Frank Zhao All rights reserved.
