Sopc uart rs232

Hi Alberto,

I don't know if a uart rs232 example is available; I've never seen one.

Anyway, if you've already read the ip user guide, you may take a look to the device HAL driver in \ip\altera\sopc_builder_ip\altera_avalon_uart\HAL

I think it is easy to integrate it in your application.

Regards

Thank you Cris.

I've tried again with the ip simple example and I get it work, maybe I will go for the HAL API code now.

Regards.

Alberto.

Hi,

Please can you tell me how you processed to getting it done because I am trying it unsuccessfully since 2 weeks.

I used the step by step example from the doc 351 (simulating nios ii embedded processordesigns) but I couldn't simulate it within Modelsim.

Please any advice would be appreciate

Hi.

I'm not simulating this, I'm running it in real word, and it works perfect, just the exactly code in the doc.

Cheers.

Hi,

Please can you tell me which code do you means?

I don't get it. I intend to test my uart. How should I start?

Please Help

This is a part of my test code.

Cheers.

Alberto.

 int count = 0;
 int largo_cadena = 0;
 char* msg = "Detected the character 't'.\n";
 FILE* fp;
 IOWR(RTS_BASE,0,1); //
 DEMO_PRINTF("In UART.\n");
 fp = fopen ("/dev/serial", "r+"); //Open file for reading and writing
    if (fp)
    {
    cursorX=0;
    cursorY=-1;
    DEMO_PRINTF("UART in ready.\n");
    IOWR(RTS_BASE,0,0); //
    largo_cadena = getc(fp);       // Get string size
    IOWR(RTS_BASE,0,1); //
    int prompt;
    while (1){
        for(i=0;i<largo_cadena;i++){
          prompt=32;
        }
        i=-1;
        while (1) //
        { // Loop until we receive a 'v'.
        IOWR(RTS_BASE,0,0); //
        prompt = getc(fp);  // Get a character from the UART. 
        IOWR(RTS_BASE,0,1); // 
        if (prompt == 13) {
            cursorY++;
            DEMO_PRINTF("Find a  Enter.\n");
        }
        if (prompt == 255) {
            break;
        }
        i++;
        DEMO_PRINTF("%c", prompt);
        }
     i=i-1;
     DEMO_PRINTF("Largo cadena: %d\n", largo_cadena);
     TMostrar_String(cursorX, cursorY, 0, 0, 0xFFFE, 0, prompt, largo_cadena-1, Fuente);
     usleep(500000);
    }
    DEMO_PRINTF("Out UART.\n");
    fprintf(fp, "Closing the UART file.\n");
    fclose (fp);
    }

Hi there are many undefined expressions on your example: Can you send me the zipped file on my private email? [email protected]

I would appreciate it.........

The UART example is complete, forget the cursorX, cursorY, RTS_BASE, etc.

You shouldn't need more.
