#163287 - Serial communication USART |
Hello
I try to use ATMEGA8 to vwrtite char to RS232 (using hyper terminal) a very simple code can not write any thing. I use CodeVisionAVR // USART initialization // Communication Parameters: 8 Data, 1 Stop, No Parity // USART Receiver: On // USART Transmitter: On // USART Mode: Asynchronous // USART Baud rate: 1200 UCSRA=0x00; UCSRB=0x18; UCSRC=0x86; UBRRH=0x00; UBRRL=0xB9; printf("This is a test of USART.r"); I prefer use internal clock(no crystal) I program with this command avrdude -p atmega8 -P usb -c usbasp -U flash:w:tst.hex shuld I use fuse? or there other problam? |
