Before I start re-inventing the wheel, is there any chance that someone here has done Micromite compatible code for the Wii Classic Controller?

Thanks

Jeff, take a look here for the Nunchuck.

However, regarding the Classic controller I personally have not seen anything.

I've got some spin code here for the Wii Classic controller, I'll look at starting to convert it next week.

Hi Jeff

This is code for a WII classic controller in picaxe code.

It should not be to difficult to convert to micromite

I do not have a controller now so I can not attempt to convert and test.

If I understand correctly, the Classic Controller is I2C address &hA4 which the Micromite is unwilling to accept. Have I missed something or uncovered a bug?

Hi Jeff,

According to instructibles the address is &H52

Aha!

A word of caution.. Those china made clones do NOT work on the same as the branded Wii(R) classic controller. I just switched to an actual license product and started getting data.

Jeff,

It wouldnt be because of the selected controller channel would it?

Maybe your original remote (presumably controller 1) was set at &H52, and as you added new controllers they adopted another address? For User 2,3,4 etc?

Just theorising.

Maybe. I'll have to do some more research after I get the real stick working.

BTW, how do I 'bit shift' on the Micromite? :)

Oldbitcollector said BTW, how do I 'bit shift' on the Micromite? :)

If x is your 'original' number then:

(x *2) AND &hFF [to shift left]
or
(x AND &hFE) / 2 [to shift right]

Use additional AND statement to extract bit required . . .

I was looking over my digital IF statement checking code this morning and thinking that it might be a good idea to change that method to a binary 'and' method as the decimal numbers will change when multiple buttons are pressed.
