So, I should just add these command to my file .hal? Right? Or I should compilate a particular module? And then I can link without problem stepgen to parport pins just with: net stepgen.4.step => parport.0.pin-09-out net stepgen.4.dir => parport.0.pin-08-out net stepgen.5.step => parport.0.pin-07-out net stepgen.5.dir => parport.0.pin-06-out In this way I can combine the two motor to have the rotation and the elevation of wirst? ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity, and more.
