Serial communication (Data receive) using AVR Microcontroller (ATmega16) USART

Communication between two entities is important for the information flow to take place. In general the information transport system can be parallel in which the complete byte of data is sent at a time, with each bit having a separate dedicated line or it can be serial where only one communication line is available which […]

Serial communication (USART) with different frame size using AVR microcontroller

The previous article explains serial communication using 8-bit data transfer. AVR microcontroller also supports serial data transfer with frame size of 5, 6, 7 and 9 data bits. The size of data frame can be adjusted according to application. For example, consider a system that needs to transmit only ASCII codes as data. In this
