18 USART C code examples showing how to configure the USART for transmitting and receiving data

Microcontroller register level programming for the ATmega2560

This nutshell gives two C code examples of how to configure the USART for transmitting and receiving data. The first uses a structure diagram for the code design and configures the USART for no parity, 8 data bits, 1 stop bit, and a baud rate of 9600. The second code uses a state diagram for its design and configures the USART for even parity, 5 data bits, 2 stop bits and a baud rate of 150. The nutshell gives a step-by-step guide in how to set up the registers
