ICC / Propeller Beginner, cannot get terminal to work using printf examples

lurker93

Hello everyone!
I searched for icc terminal but wasn't able to find an answer to my question.· I want to splash information on the terminal emulator on my ICC software but nothing is ever displayed.· The propeller is on Com 6 of my laptop on a usb port.
Suggestions?
Thanks,
Scott

Hi Scott,

I don't use ICC, so can't help with specifics, but I hope the following is useful: Are you *sure* the Propeller's been programmed correctly (e.g. you've downloaded a simple LED blinker)?

Sorry if that's teaching you to 'suck eggs'.

You'll always have as many take-offs as landings, the trick is to be sure you can take-off again

Yes, I used the blink LED program which I used to blink the LED's. In the same program after turning the led on and then off, I would fire a printf statement. Again, nothing on the terminal. Also I had no led activity on the serial board of my professional development board either. So it seems maybe I haven't told the propeller what the std out is?

Hmmm, OK, so you definitely have a working serial connection. As I said, I'm not a user of ICC (I'm not even a C programmer!), so you're being lead by the 'blind' here!

Have you included the stdio? (Not sure how to do that, but I guess you are?) I expect you'll need to do that, and maybe tell ICC which pins your Tx/Rx are on too...

Beyond that, I'm not sure if I can help.

Hope that helps though.

Here is the code

#include <stdio.h>
#include <asio.h>
#include <propeller.h>

void BlinkLED(void);

main()
{
asio_init(57600);

while (1)
{
DIRA = 1 << 16;
OUTA ^= DIRA;
msleep(250/2);
OUTA ^= DIRA;
msleep(500/2);
printf("hello world\n");
}
}

Are stdio.h & asio.h from ICC? The only code I found - from OBEX - has the following (albeit, not for serial comm's, but for TV_Text):

#include <ctype.h>
#include <stdlib.h>
#include <string.h>
#include <propeller.h>

Otherwise, to my untrained eye, your code looks OK to me!

I don't think that is it, if I were calling a function that wasn't defined I would get a compiler error.

bump help!

OK, I just tried the examples.prop\printf\hello.prj under 7.04 and it works fine. The code looks pretty similar to above. What version of the IDE are you using? Help->About tells. Presumably you also have the Project->Options->Target->""ASync IO" box checked (you must be, otherwise you will get an undefined...)

ASync IO checked!
Thanks,

And you enabled the right com port on the Tools->EnvOptions->Terminal tab? 7.03A should be fine....

COM 6 57600
Still not workinig...:-(

Scott...when you set DIRA = (1 << 16), you overrode the direction bits for the serial port which are set in asio_init from the defs in <asio.h>.

Try this:

#include <stdio.h>
#include <asio.h>
#include <propeller.h>

void BlinkLED(void);

main()
{
asio_init(57600);

// [noparse][[/noparse]RX] [noparse][[/noparse]TX] [noparse][[/noparse]LED]
DIRA = (0 << 31) | (1 << 30) | (1 << 16); // --->>better coded as: DIRA |= (1 << 16);

while (1)
{
OUTA ^= (1 <<16);
msleep(250/2);
OUTA ^= 1 <<16;
msleep(500/2);
printf("hello world\n");
}
}
