PutTile16x16 Pixels + Attributes

[oblo]

Hi all

I'm trying to use britlion's putTile library but I'm getting screen garbage instead of a defined 2x2 UDG. For instance, please look at this code that defines a 2x2 circle:

Code:

Dim circulo(31) As uByte => { _
      0, 63, 64, 67, 79, 79, 95, 95, _        REM bloque circulo 1 de 4
      0,252,  2,194,242,242,250,250, _
     95, 95, 79, 79, 67, 64, 63,  0, _
    250,250,242,242,194,  2,252,  0 _
}
Poke uInteger 23675, (@circulo (0))

putTile (10,10,@circulo)

Instead of printing a 2x2 circle with an outside square, it prints some screen garbage, including flashing sprites, so I must be reading and/or writing in a wrong memory address.
Please, could you tell me what is the right way to deal with putTile and 2x2 sprites?

Thanks and regards
