Bitfield draw error

[yarkomar18]

Bitfield can’t be drawn, the script gives an error :(

[
    { "name": "IPO",   "bits": 8, "attr": "RO" },
    {                  "bits": 7 },
    { "name": "BRK",   "bits": 5, "attr": "RW", "type": 4 },
    { "name": "CPK",   "bits": 1 },
    { "name": "Clear", "bits": 3 },
    { "bits": 8 }
]

./wavedromtikz.py wavedrom bitfield.drom

Traceback (most recent call last):

    hscale = wavedrom.get("config", {}).get("hscale",1)

But simple timing diagrams with no problem, thank you very much for that!

Your wavedrom definition is not correct (quickly checked via: https://wavedrom.com/editor.html). it should be:

{ reg:[
    { "name": "IPO",   "bits": 8, "attr": "RO" },
    {                  "bits": 7 },
    { "name": "BRK",   "bits": 5, "attr": "RW", "type": 4 },
    { "name": "CPK",   "bits": 1 },
    { "name": "Clear", "bits": 3 },
    { "bits": 8 }
]}

So I'm expect a dictionary, and you gave me a list.. so the code will trow a fit at you when try to fetch the config :D As this is just a simple script, I don't do a formatting check on the wavedrom input (I should but I don't have much time now). Anywhay I'll leave this issue open as a todo.
