ATmega128 USART assyncronous connection

#1 · November 27, 2024, 6:17 pm

I made a program for ATmega128 for USART assyncronous connection, specifically.

However, i have no idea how i get or send stuff, i probably need a serial port/monitor. How do i connect it to the ATmega?

Hi.

You can use Serial Terminal (click on "Serial terminal"): https://simulide.com/p/component-list/#peripherals

i tried to use the serial terminal, by connecting Rx to PD2 and Tx to PD3 (Rx and Tx of USART1), but nothing is happening
I KNOW this code works cuz in a real ATmega128, it worked connected to a real computer

Maybe try Rx to Tx and Tx to Rx.

Also I'm assuming that the Serial Terminal is configured for the same baudrate, etc than the USART in the Atmega.

It is set to 9600, like the default one.

Ill send the hex file tomorow, and maybe the sim1 file if u wish to see if it's well done
