History of HalSchematicsUsingGschem

2010 01 17

 I added thread components (base,servo user1,2,3,4)
 each with 32 priority outputs
 the component is dbl-clicked to edit its speed (u32)
 it has 32 numbered pins (prioritized) to connect to functions
 (do i need corresponding input pins for and gates et al?)
 
 to test the tool, i created a schematic of 'stepper_mm' from ...configs/stepper
 this was to compare the hand generated .hal to the automated .halmost file
 
 the schematics, files, netlists and codes are here
 

 the differences between the /config files show what needs to be done...
   a) naming conventions need to be constant thru HAL
       motionDOTservoDOTlast-period  versus   motionDASHcommandDASHhandler
       (the former shows inheritance the latter is a bastard :P
   b) containers must be respected and kept together as much as possible
       motmod contains motion and axis
   c) division must be used to avoid huge widgets
       parport functions occur once for all parports used,
       it'd be redundant to have the functions in each parport widget,
       so a separate parport-function widget should exist
       so:
        make a parport-funct widget ( only one instance necessary for 1 thru N parports)
        make a parport-pin widget ( one needed for every parport)
        keep params for funcs with the func widget,
             parport readall time-max belongs with functions
        keep params for pins with the pin widget
             parport invert & reset belong with pins
       there will still be an parport-in-pins and a parport-out-pins widgets.
 
 
   d)individual halfiles wont result from a single graphic schematic
       multiple schematics dont know about other schematics
       multiple pages of one schematic may be useful
       but nets spread across files would be problematic
        (net name in file 1, pins added in file 3&6)
       i suppose its just reading all the files in a directory and building lists
 
 it may well be back to the drawing board
 esp since its getting more complicated to draw than to just text edit
