Hi Stephen, thank you for your clear description! I got inspiration from the AXIS blog at http://axis.unpy.net/01188134101 , this plays with a parameter, enabled by setting the stepgen.N.doublefreq parameter to TRUE. but obviously it was eventually implemented in another way. This is from a while ago!

The way you tell stepgen to use doublestep mode is to set stepspace to 0. This tells stepgen that it can generate a step every period, rather than needing a period (or more) for spacing. The function order in the base thread also has to be set up right, you need to run the stepgen, then parport.write, then you can do other stuff, then parport.reset. The reset-time has to be set to the longest step time needed, and you have to set parport.0.pin-xx-out-reset to 1 (it may be spelled differently, look it up) By defauilt, this is the only type of config that stepgen will generate with 2.2.x. There has been some work done on making non-doublestep setups in for 2.3, but I don't know that it's complete. - Steve ---------------------------------------------------------------------------- -- Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
