FIFOed UART BSP errors

you have to defined functions, registers, ...

I use altera IO function so I have included this file.

# include "fifoed_avalon_uart_regs.h"

an example to use the fifoeduart (read/write) :

void WriteCharUART(alt_u8 ch)

{

IOWR_FIFOED_AVALON_UART_TXDATA(USB_FIFO_UART_BASE,ch);

while (!(IORD_FIFOED_AVALON_UART_STATUS(USB_FIFO_UART_BASE) & 0x0040)); // while trdy==0

}

void WriteSentenceUART(char* text)

{

int temp = 0;

while (text[temp] != '\0')

{

WriteCharUART(text[temp]);

temp++;

if (temp == 100)

return;

}

}

void handle_io_uart_interrupts(void* context, alt_u32 id)

{

char tmp_buff;

// you can use "context" as a parameter

tmp_buff = IORD_FIFOED_AVALON_UART_RXDATA(USB_FIFO_UART_BASE);

if (tmp_buff>=0x20)

printf("| %c ", tmp_buff);

else

printf("| 0x%X ", tmp_buff);

}

int main()

{

int ctrl;

// IRQ off

IOWR_FIFOED_AVALON_UART_CONTROL(USB_FIFO_UART_BASE, 0);

// init program

…

// init uart

IOWR_FIFOED_AVALON_UART_CONTROL(USB_FIFO_UART_BASE, 128); // Enable interrupt for a read ready = caractere receive

alt_irq_register(USB_FIFO_UART_IRQ, (void *)&ctrl, handle_io_uart_interrupts);

while (1)

{

}

return 0;

}
