Buy this and convert your load cell from heusinkvelds to a potentiometer http://www.leobodnar.com/shop/index.php?main_page=product_info&cPath=73&products_id=199
(That way you can plug it into the handbrake port on v3 board,dont know the wiring. Or just buy an arduino pro micro and upload the amstudio sketch of handbrake)
I have the following situation. I have fanatec advanced paddle module and fanatec dd2, pedals are heusinkveld ultimate. Before the ultimates I had fanatec v3 pedala connected to the base. I used the analog clutch paddeles as a clutch, and they worked as a clutch pedal. I mean in game the pedal and the paddles both worked as a clutch. But now in game i can map only one as a clutch - the paddles or the ultimate pedal.
What I am trying to achieve is to get back the old functionality. For that I have kept the pcb board from fanatec v3 pedals, and I want to connect the heusinkveld clutch pedal to it. The question is how can I do this? They are different - fanatec uses hall sensor, heusinkveld use loadcell and probably input is too diffetent.
Another option is, if possible, purely software solution like mapping the heusinkveld clutch axis as fanatec (or vice versa). But also dont know how to do it,
Any help or advices or specs of the pcb boards and sensors (heusinkveld and fanatec) is appreciated.
