I did some performance testing.
The Pro Micro runs an Atmel 32u4 at 8MHz.
If the code does nothing else,
I was able to poll all pins around 13 times every 1ms,
or 13kHz.

You can adjust this if you want to.

I don't know how I can verify that I'm setting this right,
but the `rbdrum2midi` program looks at these bytes to detect hits.
I set them to 127 when a hit is detected on the digital pin.
Sending these values does not seem to cause problems with my Wii games.

* [Cheap children's drum toy](https://www.amazon.com/Electronic-Sboet-Practice-Headphone-Christmas/dp/B0CHJMYCH9/),
each pad is a momentary switch.
## Drums
I bought a [Cheap children's drum toy](https://www.amazon.com/Electronic-Sboet-Practice-Headphone-Christmas/dp/B0CHJMYCH9/)
from Amazon.
There are dozens of copies of this thing,
the one I got was on sale for $25.
I had to unscrew the cover and remove the
logic board, battery, and speaker.
The pads were connected with
a sort of ribbon connector,
which I desoldered and removed,
then placed in my own perma-proto board.
I also hooked up a 3.5mm TRS jack for the two pedals,
which I could have desoldered from the toy
(I already had these).
I'm sorry I didn't photograph or record any of this,
but it was pretty straightforward.
# Compiling
This compiles in the Arduino IDE.
It doesn't have any library dependencies.
You need to make two edits to `boards.txt`.
Instructions for this are all over the place.
Find your board, and edit the `build` lines.
Don't edit anything that doesn't say `build` on the line! I can't help you if you do this.
In my examples, I'm editing the lines for the leonardo build. Yours might be different:
it should match the board you're using.
## Build flags
This disables serial communications on the board.
leonardo.build.extra_flags={build.usb_flags} -DCDC_DISABLED
Hat tip to Nicholas Angle for figuring this out
so I didn't have to.
## VID and PID
These set the USB identifiers.
VID is the Vendor ID,
and PID is the Product ID.
`0x1bad` means "Harmonix Music",
at least, it does to the Linux kernel.
### For guitar
PID `0x004` means "Guitar controller".
leonardo.build.vid=0x1bad
leonardo.build.pid=0x0004
leonardo.build.usb_product="Mockband Guitar"
### For drums
PID `0x3110` means "Rock Band 2 drums".
This works better with all versions of Rock Band on my wii,
even if you don't use the cymbal inputs.
leonardo.build.vid=0x1bad
leonardo.build.pid=0x3110
leonardo.build.usb_product="Mockband Drums"
# Wiring
![see standard.hh for pin connections](wii-rb-std.png)
Both the guitar and drum kit I used
provide simple momentary switches:
nothing fancy like a piezo.
If you're using fancier types of inputs,
you'll need to modify the source code.
## Guitar

| RX1 | strum down |
| 2 | tilt switch |

| 14 | orange solo |
| 15 | blue solo |
| 18 | yello solo |
| 19 | red solo |
| 20 | green solo |
| 21 | no connection |
The solo buttons and wammy bar are optional.
I don't use them.
If you hook up a wammy bar,
be sure to uncomment the `#define WAMMY`
in the code!
## Drum Kit
On the drum kit,
![drum wiring](drums.png)
* Orange: kick pedal
* Solo Buttons: cymbals
* Red Solo: high hat
* Tilt: 2x kick
I think. I haven't been able to test this yet,
but the Clone Hero wiki leads me to believe this is how it works.
You can hook up a wammy bar for the drum kit,
and it will be sent the same way as the guitar.
I don't know why anyone would want this,
but I'm not going to tell you how to live your life.
