![]() But for interfacing with RS-232 devices, such as the COM port of a PC, a converter is necessary which converts the CMOS/TTL signals of the AVR to RS-232 compatible signals. Most of the AVR devices have a serial port, often called UART or USART. UCSR1A = (1 > 8) // Load upper 8-bits of the baud rate value. This document describes how to add an serial interface to an AVR. #define BAUD_PRESCALE (((F_CPU / (USART_BAUDRATE * 16UL))) - 1) #define USART_BAUDRATE 9600 // Baud Rate value AVRlib Sub-Libraries I2c Master (Bit-Bang) UART (software-based, timer interrupt driven) Pulse Output (arbitrary-frequency continuous/counted square wave). Why this problem occurring I don't know please help in this issue. In cute com its displaying the string along with some chars are missing and at the starting and end of the string its appending some hex numbers. ![]() If we were to use false as an argument then the // function will return false and skip the while loop because the UART is slower than the CPU.I want send some string to PC via serial bus.
