Uart data ready

By the way, here's the code I currently use for debugging. Id basically reads the STATUS bits and sends them to labview. It reads 64 continuosly, even if labview is writing onto rx...

# include <stdio.h># include <string.h># include "alt_types.h"# include "altera_avalon_spi.h"# include <altera_avalon_spi_regs.h># include "altera_avalon_uart.h"# include "altera_avalon_uart_regs.h"

// these includes allow us to perform a quick sanity check that the system was properly assembled in SOPC Builder# include "system.h"# include "inc/system_validation.h"# include <stddef.h>

// all helper routine includes are condensed into this one file for neatness# include "inc/main_includes.h"# include "sys/alt_irq.h"

alt_u16 status = 0;

int main(void)

{

alt_u16 new_divisor; //clk speed divisor to uart speed

alt_u32 serial_speed = 1000000; //uart speed, as to be match with labview VI. max 1250000

alt_u32 FPGA_CLK = 50000000; //set at 50Mhz in Quartus

uart_init(); // see src/uart_util.c

new_divisor = (alt_u16)(FPGA_CLK/serial_speed+0.5); //set the divisor for the uart speed wanted

IOWR_ALTERA_AVALON_UART_DIVISOR(UART_BASE, new_divisor);

validate_me();

while(1) //loop for the run||

{

if (IORD_ALTERA_AVALON_UART_STATUS(UART_BASE) & ALTERA_AVALON_UART_STATUS_TRDY_MSK)

{

status = IORD_ALTERA_AVALON_UART_STATUS(UART_BASE);

IOWR(UART_BASE,0x01, status);

}

}
