Hey,

This is a function thats send one byte to the UART

void UART1_T(unsigned char ch)

{

while((IORD_ALTERA_AVALON_UART_STATUS(UART1_BASE) & 0x040) != 0x040){ ;}

IOWR_ALTERA_AVALON_UART_TXDATA(UART1_BASE,ch);

}

You only have to change UART1_BASE address to your UART address that you can find back in your system.h file

Good luck

Regards
