DSP 56800 how to save "view array" data ?

Hi,

I'm using CW 8.0 for 56800 and USBTAP.

I need to follow the time evolution of a rapidly changing float variable (every 10 ms) , so I tried to setup a

visualization point + data visualization but I've discovered that this is extremely slow. So I've moved to

the solution of defining an array of 1000 elements, then I fill the array every 10 ms, and finally I

suspend the execution and use data -> view array to look at all the elements. This works

fine, but the problem is that I'm not able to export the content of this window to to

analyze and plot the data. ctlr +c does not work, copy is greyed ... the only solution

that I've found is to use a window capture program (snagit) that also converts to text .. but it is a

real pain. Does it exist another way to dump this data or which is the standard method of studying

the behaviour of a changing variable without slowering the system ?

thanks for your help

franco

I would like to know this too. Same config as the OP, except for IDE 7.3.

Options I have explored are:

-Freemaster: slow (10ms/ variable, if you have say 3 variables a variable is update at 30ms. This in spite of an update rateof 0.5ms from the target). Freemaster is also unreliable.

-tcl sripts. Arcane, difficult to figure out

-COM: see tcl

-command window , using command that are logged. Unreliable (e.g. IDE crashes if you display large amounts of memory), unable to display data memory, unable to evaluate a c pointer variable e.g. info_ptr->current

All I want it the content of my high speed buffer. Is this too much to ask?

What about just a little export or save as or something in the IDE?

I find this IDE very "closed", slow, unreliable and a PITA to use.
