I'm sorry, I've tested it, and it's really no good, we'll think of a way to update it in a later version. I hope you are patient. Thank you for your letter!
Tu, You have spaces within your add command.
With the exception of the single space after add, there should be no other spaces.
This is a general rule for all commands - no embedded spaces within the parameters.
BUG still exist in version 0.34.
Pleas Nextion DEV help us!
The current waveform implementation is expecting numeric values and cannot be parsed variable.
add 1,0,0 ... add 1,0,37 ... add 1,0,255
The way it was implemented allows a connecting MCU to pass values, but not via Nextion variables.
Thanks for your reply.
But I tried with the number, also same error :(
Oopps, remove spaces and it works!
Great thanks! Sorry for silly question :P
I have the same problem.
9 months are a very long time, solved the problem in 2016 ?
Devs promised to fix in the next release
Same problem in 0.36 :( any workarounds?
Now I use 0.39. And cannot add value to waveform also.
It's always said: "Error: Invalid Variables: 0( Double click to jump to code)"
add 1, 0, h0.val
Waveform ID is 1, 1 channel.
h0 is a slider with min=0, max=255
Also tried which others options, but still cannot.
