ATmega128 USART assyncronous connection
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.
it didnt work still
Maybe share something that I can try?
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

this is the USART setup:
UBRR1H = 0;
UBRR1L = 207;
UCSR1A = 0b00000010;
UCSR1B = 0b10011000;
UCSR1C = 0b00001110;
(as u can see, or not, i enable double speed, maybe its that the issue? it uses the next baudrate value, maybe i need to put the next baudrate too in the monitor)
im sending my simulation file and the hex file with the program. try sending s and d. its suposed to switch to s mode, and then u can use the switches to make the DC motor rotate

Thank you.
Found the problem: an error in a configuration file, to fix it replace the file attached here:
data/AVR/mega64_128/mega64_perif.xml
Also connect Rx to Tx and Tx to Rx:
