[AVR] UART with atmega128 question ??

[bianchi77]

Guys,

I tried to compile :
#define UART0_RECEIVE_INTERRUPT SIG_UART0_RECV

and got :
attempt to use poisoned "SIG_UART0_RECV"

I'm using avr studio 6.1

any ideas on how to rectify it ?

Thanks

Hi,

You need to use UART0_RX_vect instead of SIG_UART0_RECV

I feel no need to define macros you can use directly Interupt service routine.
ISR(USART0_RX_vect)
{
......
}
