debug + propeller

Hi,

I would just like to know if it is possible to debug a propeller chiplike like you do a bs2 chip? if so how?

nvale most people use the parallax serial terminal that comes with the propeller tool and also a parallax serial terminal.spin program to use in your program to display number's and string's. Include it in your program like this

Con                                                                     
                                                                        
  _CLKMODE = XTAL1 + PLL16X                                             
  _XINFREQ = 5_000_000                                                  
                                                                        
Var                                                                     
                                                                        
                                                                        
Obj                                                                     
                                                                        
  pst : "parallax serial terminal"                                        
                                                                        
Pub main                                                         
                                                                        
  pst.startrxtx(31, 30, 0, 115200) 'start serial terminal                   
  waitcnt(clkfreq*3+cnt)       'wait 3 seconds for time to open terminal        

Then within the rest of your code you would print a string like this

pst.str(string("This is a string"))

or a number

a := 12
pst.dec(a)

Edit: spelling and starting of object parallax serial terminal

One of the tricks I used in many of my programs is to start a secondary Spin cog that prints variables I'm interest in to PST -- in the "background" and unattended.

I would often use the TV_TEXT object calling it debug in the OBJ declaration. In the first few lines of the main method, I'd initialize the TV_TEXT object, then I could insert a debug.str(string("Here I am",13,10)) or something similar wherever I needed to know what the program was doing. I could display variable values with debug.hex(value,8) or something like that.

Not sure on how the bs2 debugs, but I've been trying viewport, and it allows some pretty cool debugging features. Including, IO display, Variable display, Pause, Step code, plus alot of other stuff I haven't even looked at.

Debugging to many people involves the ability to set breakpoints, step one line at a time through code, watch variables, change variables...
ViewPort does all this and more...
ViewPort also includes an integrated terminal with absolute and relative positioning so you can build text interfaces. You can also graph variable values in real time and watch IO states change at up to 80 million samples/second. ViewPort supports PropBasic, Spin and C.
