I am not an expert or have a big knowledge of the driver itself but it would be great to be able to change the channel width (even if it was a "dirty" solution, like manually hardcode some register values to achieve the desired channel widths). Maybe someone has any useful tips for me? I can do the "dirty work" but i just need some indications on HOW to do it.
