The gladevcp EMC_Action_MDI can be used to do pretty much the same, and you could link that action to a HAL pin change trigger (see the examples in configs/gladevcp). Doesnt win the beauty price, too, and assumes you can switch to MDI mode inter-component communication beyond HAL is worth considering IMO I can, in principle, imagine a new NML message which is just used for setting and maybe reading named/numbered parameters, and link that into a widget, but that's trés sportif; I actually saw the need for that coming when Pavel and me worked on gladevcp, because it's an obious feature if that's considered generally useful, I'd look into it -- semi-related: I've been toying with named HAL pins in the interpreter short of abusing a comment for a hal pin name like 'o<readpin> call (comp.pin-name)' which is a royal wart one would need to think about extending the o-word name syntax a bit so it can convey pin names this is not that difficult but backwards compatibility is an issue also, I've done an experimental named parameter syntax which pulls values from the ini file like so: #<_[section]name> and it would fish out a value from [SECTION] NAME=<value> but then this is setup time, not runtime and probably not what you need -mah Am 16.08.2011 um 17:47 schrieb andy pugh: > Is there anyway for a bash script to write values directly to numbered > parameters? > > halcmd setp motion.analog-in-00 works, but it a bit clunky. > > A related query is whether a GladeVCP number box can be linked direct > to a parameter.
