Yes, I found that too. I built my code based on the GS2 module and Michael's code. > Early on, I avoided using the GS2 component as a sample because it > appeared that it had to be compiled within the LinuxCNC tree.

The idea was to have one user hal module that would be configured by an ini file, eg loadusr -W vfdmodule sj2002.ini All that would change would be the ini file. My module is driven by the two tables, currently in the code, but I planned to move the vfd specific part to the configuration file. The tables define the Modbus registers and coils, and which ones you want to appear as hal pins. ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
