Elm Chan ( MCU ) + UHU ( power ) = BG DC SERVO

[emilcnc]

Hello,
Here is 'my' version of Elm Chan servo controller.
'MY' because many people helped me and correct me many times.
Thanks to Kreutz, H.O ( Henrik ), HJozsi, Vlady, Epineh !!
Power stage is from UHU servo.
Servo controller is working ! but please wait for the new version of PCB, because i did some mistakes on wiring TL082. ( current limit )
In the new version you will find 75176 for encoder interface, 4N37 for sending ERROR signal outside ... and connection between current limit signal to 2313 ( if it is needed, when the software is improved )

I will attach:
1. new project - servo.zip - Eagle schematics and board ( not tested - please wait )
2. new project - exported to images
3. old project - pics of working servo .... testing table

TODO in progress:
1. manual routing of new PCB ( wait for new design )
2. understanding source code.
3. testing ...

I don't think tl082 can work on single supplier
