ActivityBot2013-10-31 problem

Rsadeika

I just installed SimpleIDE 0.9.44 and the ActivityBot2013-10-31 folder, and after reading the Documentation for abdrive, I noticed a command called 'drive_getTics()'. So, I decided to see what that is all about, but I keep getting a compile error, 'no such command', even though I have the '#include "abdrive.h" in my program. Is there a problem with the abdrive library, or is something else going on? Since this is not my first time with the IDE, I thought I had all the correct libraries associated with the program.

/*
  test_AB.c

*/
#include "simpletools.h"
#include "abdrive.h"

int main()
{
  // Add startup code here.
  drive_getTics();
 
  while(1)
  {
    // Add main loop code here.
    
  }  
}

Hi Ray,

Please uninstall 0-9-44, and install SimpleIDE 0-9-45 which was posted today to:

http://learn.parallax.com/propeller-c-set-simpleide

I accidentally posted the wrong package the first time. Sorry about that.

I just installed 0-9-45, and I noticed, in the new Simple Libraries folder which contains a Motor folder, but it does not have the abdrive library. Are we supposed to still get that at the Learn site and copy it to the Simple Libraries folder? Will that be the latest abdrive library, considering that the Learn site still shows 0-9-43 as the version that should be downloaded? I thought that the abdrive stuff would have been included in the latest update.

Hi Ray,

There's a "Documentation abdrive Library.html" page in your ActivityBot2013-10-31 folder that explains the library's functions. In the drive_getTicks section, it explains that the *left and *right parameters have to be pointers to the variables that you want loaded with the left and right ticks. Here is an example that declares variables and passes their pointers to the drive_getTicks function:

#include "simpletools.h"
#include "abdrive.h"

int ticksL, ticksR;

int main()                   
{
  drive_speed(32, 32);
  for(int i = 0; i < 4; i++)
  {
    drive_getTicks(&ticksL, &ticksR);
    print("ticksL = %d, ticksR = %d \n", ticksL, ticksR); 
    pause(1000);
  }
  drive_speed(0, 0);
}

Hi Ray,

The abdrive library is still getting updated on a regular basis, so we are not including it with the software yet. So yes, please copy the ActivityBot2013-10-31 folder back into Simple Libraries and restart SimpleIDE. Also make sure to correct your drive_getTicks call (discussed in previous post).

The Learn site has the SimpleIDE 0.9.45 installers posted for Windows and Mac.

(@Ray, Steve just happened to see your email within the hour of posting the 0-9-45 Windows installer to the open source project code repository. We had not yet finished updating our own web resources to use the new packages.)

Sorry for any confusion.

Rsadeika

No confusion, things just got out of sync. I got 0-9-45 installed, and it seems to be working as expected, plus the 'drive_getTicks()' is working as expected, so everything is good...

I was just looking through SimpleIDE Libraries and I cannot find sonyremote.h, where did it go?

Hi Ray,

The tutorial for this came out a few days ago with a download. We'll probably add it to the next SimpleIDE. So for now, the IR remote library is a download on this page:

http://learn.parallax.com/propeller-c-simple-devices/ir-receiver-and-remote

Its function names are different from what you've been using, so some code updates will be necessary.
