problem on 33EP64GS506 UART2

[msamar]

hello

we are encounter problem on UART2
dosnt work
but UART1 working fine
33EP64GS506

Code: Select all

Hi,

Have you tried your code without using the UART1 at all, only UART routines ?

Regards,
Filip.

Code: Select all

UART2_Init(9600); 

Delay_ms(100);

void main()
{
   UART_Write('A');

}

the same problem also for UART2

but if i use UART1 code working fine as

Code: Select all

UART1_Init(9600); 

Delay_ms(100);

void main()
{
   UART_Write('A');

}
