Post by thread:Stimulus files

I wrote a C program to take a hex ascii input from the keyboard that creats an RS232 stimulus file for use with the MPLAB. Does that sound like what you need? >Date: Mon, 2 Feb 1998 >From: Mike Montgomery <spam_OUTmikeTakeThisOuTANALI.DEMON.CO.UK> >Subject: Stimalus files > >Hi > Does anyone have a util that will convert TEXT/BIN/HEX file > to a stimulus file to reproduce RS232 input. > >thanks

Ok all you PIC experts, listen to this I am a beginner at PIC pgming and I need to simulate an input to a PIN whilst simulating my code using MPLAB. I will need a string of inputs (several hndered values) that need to be used every time I read that pin in my code.....how do I do this? the Help file about pin stimulus suggests a maximum of 12 such stimuli....what do I do? please help. Im am currently off the PIC LIST so pls forward any replys to .....frakKILLspam@spam@snakebite.com Thank you Rock On......... >@>@>@>@>@>@>@>@>@>@>@>@>@>@>@>@>@ !! FRAK MAN !! !!

Can someone point me to a web resource that more fully explains the stimulus? The only reference I have found thus far is the one page in the MLAB manual. Specifically, to what is the 'insertion' point referenced with respect to the source code, line number, clock cycles etc.? Can you list any one or set of I/O pins, i.e.( RB0, RB4, RA2) or is the format fixed? Eric J. Marang .....crsc06KILLspam.....email.mot.com

part 0 2614 bytes content-type:application/octet-stream; (decoded 7bit) CYCLE RBO 1 1 ; comment 101 0 ;comment To be able to use this very simple file you would start the debugger, either single step or whatever. Then select "Debug/Simulator Stimulus/Pin Stimulus/Enable" from the menu. Then select the Stimulus file you want to use. This will enable your file. This still will not work. The Stimulus function is tied directy to the "Windows/Stop Watch" function in the menu. Now if you click on the Zero button in the "Stop Watch" window, this will reset the MPLAB back to cycle 0, note this does not reset the PIC simulator function. I guess what I am trying to explain is that every time you click the Zero button on the "Stop Watch" window your Stimulus file will start over again from cycle 0. This is very usefull when you want to repeated test the input signal on RB0. What I don't find usefull and have highlighted to Microchip is that it is very clumbsy to enable and disable the Stimulus file, and there can only be one file active at a time. One file is fine for most cases because you can specify multiply pins in the file, but what I have tried to do is create multiply Stimulus files to emulate different buttons on IR remote control. I asked Microchip to consider being able to configure a button in the Async Stimulus window to use a certain Stimulus file, this way you could simply enable any number of stimulus files with a simply click. Anyway attached is my example of a Stimulus file that I use to emulate the CH+ button on my Sony TV Remote. I hope this helps, if not please send me a Email and I will try to explain it better.

I did the MPLAB tutorial on stimulus files and their sample works fine. I made this stimulus file for myself, and it crashes MPLAB CYCLE RB0 1 0 500 1 750 0 1000 1 1500 0 I'm trying to figure out how to get around this. Clearly MPLAB shouldn't crash, but am I doing something wrong here? My experience is that usually when I start using a new tool I exercise corners an experienced user never would, so I sometimes run into bugs that haven't been fixed. So, does the above file look reasonable? -- Anniepoo Need loco motors? http://www.idiom.com/~anniepoo/depot/motors.html

Then scroll to the bottom of the page and choose "Development Systems Conference." Microchip engineers monitor this conference and other users help with problems here , too. -- ___________________________ | Darrel Johansen | | tempe, arizona | | EraseMEdarreljspam_OUTTakeThisOuTprimenet.com | |_________________________|
