craig,

yes i have read it.
i thought the 'EncScale' was a variable
the largest problem i am having with this script is the line "local hreg = mc.mcRegGetHandle(inst, 'iRegs0/EncScale')"
this is the exact same line i have in another script "local hreg = mc.mcRegGetHandle(inst, 'Encoder_0')"
the second works the first does not
both are registers

Mach4 General Discussion / write to a register

« on: February 27, 2019, 10:08:07 AM »

Ok.
Yesterday I had a script that would read a register then set another register.
I realized that is not what I needed and deleted it.
Now I need to read a dro then write the value to a register.
Of course it is not working so I am once again asking for help.
The script editor is telling me the problem is the last line.
Here is the code:

--read value from dro
local EncScale = scr.GetProperty('droEncScale', 'Value')
--set register handle
local hreg = mc.mcRegGetHandle(inst, 'iRegs0/EncScale')
--set register
local mc.mcRegSetValue(hreg,'EncScale')


BTW how to do this will be written down this time.

Thanks,
Bill

The attached code is giving me a nil value on the first line.
What do I have wrong.

Craig,

I had the registers taken care of but thanks for making sure I had it all.
I will work on the rest in a little while.

Thanks,
