Mesa 5i25 custom bitfile

Hallo Gemeinde,

ich benutze eine Mesa 5i25 (PROB_RFX2) um 3 Achsen zu steuern.
(Closed Loop mit Stepper und Glasmassstab.)
X und Y funktionieren einwandfrei nur bekomme ich Z nicht zum laufen da die Karte nur 2 Eingänge für Encoder hat.

Ist es möglich ohne Daugtherboard 3 Eingänge für Encoder zu erzeugen? Zum Beispiel durch ein entsprechendes Bitfile ?

<q>Hello community ,

I use a Mesa 5i25 ( PROB_RFX2 ) to control 3 axes .
( Closed Loop with Stepper and glass scale . )
X and Y function properly only I get Z not to run because the map only 2 inputs for encoder has .

Is it possible without Daugtherboard 3 inputs to produce for encoder ? For example, by a corresponding bitfile ? </q>

Sure, can you post your desired P3 and P2 pinout here

Hello PCW

currently I have no fixed pinout as I am still trying on .

To test all axes together I need 3 Stepgen and 3 encoder .
The pins should be on P3 .
For example,

01 - step 0
02 - dir 0
03 - step 1
04 - dir 1
05 - step 2
06 - dir 2
07 - A 0
08 - B 0
09 - I 0
10 - A 1
11 - B 1
12 - I 1
13 - A 2
14 - B 2
15 - I 2





thx

Hello.

When I try it myself I get from ISE 2 Error. But i change nothing! Whats wrong?
Version 14.7

Not sure why you have that error
I just tried compiling from the sources and didn't find an issue

are you using the fivei25.xise project file and the latest hostmot2.zip?
MD5 (hostmot2.zip) = 537d9e74c60b1d0864163f0b75eab74d

the error is that the files cannot be found

Actually only the hostmot2.zip file needs to be unzipped
the other zip files:

etherhm2.zip
resmod.zip
sslbp.zip
twiddler.zip
serhm2.zip
ssremote.zip

Are all sources for machine language code that goes in various processor ROM VHDL files
They are provided for reference but are not needed (or usable) by ISE

Ok i try it with the actually files.

Surprise ! It works! :woohoo: :woohoo: :woohoo:

Many thanks for your help.

Talla,
Did you have to do any other changes in ise 14.7 ? , i have just moved from ise 13.1 and having problems that the map will not
compile and errors .
