In embedded systems, a simple function rarely exists alone. A simple pushbutton and LEDs controller is useful but if that controller cannot report when a user has pressed a button or share the status its LED indicate, the controllers are not worth their value. Many embedded systems include peripheral devices connected to the microprocessor in…

AVR (ATmega32) contains some in-built registers for TWI communication which not only reduce the level of complexity but also make the whole communication process smooth. These registers have been explained in this tutorial. 1.        TWBR (TWI Bit Rate Register) : TWBR7 TWBR6 TWBR5 TWBR4 TWBR3 TWBR2 TWBR1 TWBR0   This register is used in master…
