Hi,

I had a similar project for driving a Pioneer HU using an Arduino and a MCP41100, except I wasn't doing anything related to the VAN-bus since it seemed too obscure for me at the time I wrote it. Instead, I wired the remote stalk directly to my Arduino but thanks to all your recent work on the VAN bus, I overcame my "fear", big thanks for your work 😃

I have some suggestions regarding the Pioneer remotes and before I would like to get your input on it:

• It's unclear which variant of the MPC41xxx you are using. The overall resistance for potentiometer is not the same for all MPC41 and that changes the resistance calculation.
  
  So we could choose an MPC41xxx package and stick to it or allow the "user" to set value of the overall resistance used (maybe in the Pioneer_MCP4100_Remote constructor). The later option allows for better flexibility and ease-of-use.

I haven't properly looked at how you get the stalk commands for the VAN bus yet but from what I've seen, it may be possible to known if a particular button on the stalk command is being held. I think this can actually be helpful to, e.g.:

• send source to the HU if the SRC button of the stalk is shortly pressed
• send mute to the HU if the SRC button of the stalk is held for, say, 1sec
• send on/off to the HU if the SRC button of the stalk is held for 2secs
  I hope you'll get the idea.
