Thanks for the firmware file! When I try to flash it with mesaflash, I get the error Invalid bitfile header. It looks like this is a raw Xilinx ISE/Vivado .bit file. Could you please provide the firmware in the proper format for mesaflash (with the MESA header, or as a .bin file for the 7i90)?

Hey guys,
I want to measure the internal temp of my jianken ATC spindle. I have a NTC with a classic voltage divider setup, and at room temperature the V_out of this divider carries 12V. (Measured against GND with a multimeter).

However, as soon as I put this cable into analog_in1 of my Mesa 7i76eu, the voltage drops to 8v, and thous the calculated temperature is garbage...

Any ideas why this is happening? 

regards
Sebastian

 

 

Note that the pins listed in the source file comments are DB25 pins

so

7I90  P4.1  --> DB25.1
7I90  P4.3  --> DB25.14
7I90  P4.5  --> DB25.2

etc

Thanks a lot for the explanation! I will try this solution.

Hi thanks for your answer. Yes i saw your Macros and i think they look really good. You did and do a great jobs there for all, thank you for that! But as far as i understand them, you can only use one at a time right? and there is also no macro for a free contur ? or do i miss something? 

edit: oh sorry my bad, they are from andypugh of course! so thanks andy

Note that this is not a standard configuration as the 7I90 is a 50 pin connector FPGA card
and the 7I85S is s 25 pin FPGA card daughtercard. I pinned this out so a flat cable adapter
should be relatively simple (look at the included VHD source file for the pinout)

 

This has 3 stepgens and 1 PWMgen, 4 encoders and a sserial port
(on the 7I85S) 
 

Very briefly:

In the hal file (use the sample: basic7i97 or use MesaCT to generate the basic configurations)
The PID output pin connects to the PWM value pin. You would change this connection to 
add the abs component so you have:

PID output --> abs in --> abs out --> PWM value

That is, for example, in the basic7i97 hal file you have:

net x-output     => [HMOT](CARD0).pwmgen.00.value

This would need to change to:

net x-output     => abs.0.in
net abs-x-output    <= abs.0.out
net abs-x-output     => [HMOT](CARD0).pwmgen.00.value

 

 

i'm not even close to being done but got the viewer hooked into a custom .ui file. i think i am on the downhill side of things now but this seems to be the hard way to do it but since i have so much time in teaching myself this i will finish what i started. but basically, it's done in OpenGL.

I understand, thank you! The duplication was unintentional. My apologies

Hallo Franz,
hast du die Kombination ServoStar - EL6751 in der Zwischenzeit noch zum Laufen gebracht?

Schöne Grüße,
Gerhard

You posted the same question twice, and that is not good as it makes it impossible for us to follow what has been answered, and for users to find the correct info when they need to.
Duplicate post was deleted.
Thank you.

Thanks a lot for the answer.

Good message: it is doable and I can use the RS Pro amplifier. Unfortunately the Mattke not. In any case, I have to forget the Tach function of the motors.

Sorry for my further questions - I`m an absolute beginner and not an experienced programmer. This are my first steps in learning to run.

Below I have formulated my questions in red font. I need to understand, whether the I/Os on my MESA are sufficient by number and by functionality.
 
Thanks a lot and best regards
Hartwig

Sorry, I didn’t quite understand what you mean by "without double posting". Could you please explain?
