# CNC Rotary Macropad
## Overview
https://youtu.be/UmJdvE2cYZE
## CNC MacroPad
You can build a dedicated macropad for controlling your 3D printing slicing software with snap-part NeoKey switches, a CNC rotary encoder and the Feather RP2040 running CircuitPython.
## Glowing Hotkeys
Each key is assigned to a shortcut for the popular Ultimaker CURA slicing software. The large (and heavy) rotary encoder can rotate around your model and even zoom in/out!
## Dynamic Rotary Encoder
The CNC rotary encoder can switch between three different modes. The lower three key switches can toggle between each mode. This makes the rotary encoder much more versatile allowing you to quickly switch between keyboard arrow keys and the mouse scroll wheel.
## Customizable Macropad
The CircuitPython code allows for easily customization. Change the keyboard shortcuts to control any number of software such as CAD, graphics and video editing applications.

# CNC Rotary Macropad
## Install CircuitPython
[CircuitPython](https://github.com/adafruit/circuitpython) is a derivative of [MicroPython](https://micropython.org) designed to simplify experimentation and education on low-cost microcontrollers. It makes it easier than ever to get prototyping by requiring no upfront desktop software downloads. Simply copy and edit files on the **CIRCUITPY** drive to iterate.
## CircuitPython Quickstart
Follow this step-by-step to quickly get CircuitPython running on your board.
[Download the latest version of CircuitPython for this board via circuitpython.org](https://circuitpython.org/board/adafruit_feather_rp2040/)
**Click the link above to download the latest CircuitPython UF2 file.**
Save it wherever is convenient for you.
To enter the bootloader, hold down the **BOOT/**** BOOTSEL button**(highlighted in red above), and while continuing to hold it (don't let go!), press and release the**reset button**(highlighted in red or blue above). **Continue to hold the BOOT/BOOTSEL button until the RPI-RP2 drive appears!**
If the drive does not appear, release all the buttons, and then repeat the process above.
You can also start with your board unplugged from USB, press and hold the BOOTSEL button (highlighted in red above), continue to hold it while plugging it into USB, and wait for the drive to appear before releasing the button.
A lot of people end up using charge-only USB cables and it is very frustrating! **Make sure you have a USB cable you know is good for data sync.**
You will see a new disk drive appear called **RPI-RP2**.
Drag the **adafruit\_circuitpython\_etc.uf2** file to **RPI-RP2.**
The **RPI-RP2** drive will disappear and a new disk drive called **CIRCUITPY** will appear.
That's it, you're done! :)
## Safe Mode
You want to edit your **code.py** or modify the files on your **CIRCUITPY** drive, but find that you can't. Perhaps your board has gotten into a state where **CIRCUITPY** is read-only. You may have turned off the **CIRCUITPY** drive altogether. Whatever the reason, safe mode can help.
Safe mode in CircuitPython does not run any user code on startup, and disables auto-reload. This means a few things. First, safe mode _bypasses any code in_ **boot.py** (where you can set **CIRCUITPY** read-only or turn it off completely). Second, _it does not run the code in_ **code.py**. And finally, _it does not automatically soft-reload when data is written to the_ **CIRCUITPY** _drive_.
Therefore, whatever you may have done to put your board in a non-interactive state, safe mode gives you the opportunity to correct it without losing all of the data on the **CIRCUITPY** drive.
### Entering Safe Mode
To enter safe mode when using CircuitPython, plug in your board or hit reset (highlighted in red above). Immediately after the board starts up or resets, it waits 1000ms. On some boards, the onboard status LED (highlighted in green above) will blink yellow during that time. If you press reset during that 1000ms, the board will start up in safe mode. It can be difficult to react to the yellow LED, so you may want to think of it simply as a slow double click of the reset button. (Remember, a fast double click of reset enters the bootloader.)
### In Safe Mode
If you successfully enter safe mode on CircuitPython, the LED will intermittently blink yellow three times.
If you connect to the serial console, you'll find the following message.
```terminal
Auto-reload is off.
Running in safe mode! Not running saved code.
CircuitPython is in safe mode because you pressed the reset button during boot. Press again to exit safe mode.
Press any key to enter the REPL. Use CTRL-D to reload.
```
You can now edit the contents of the **CIRCUITPY** drive. Remember, _your code will not run until you press the reset button, or unplug and plug in your board, to get out of safe mode._
## Flash Resetting UF2
If your board ever gets into a really _weird_ state and CIRCUITPY doesn't show up as a disk drive after installing CircuitPython, try loading this 'nuke' UF2 to RPI-RP2. which will do a 'deep clean' on your Flash Memory. **You will lose all the files on the board** , but at least you'll be able to revive it! After loading this UF2, follow the steps above to re-install CircuitPython.

# CNC Rotary Macropad
## Code the Macropad
Once you've finished setting up your Feather RP2040 with CircuitPython, you can access the code and necessary libraries by downloading the Project Bundle.
To do this, click on the **Download Project Bundle** button in the window below. It will download to your computer as a zipped folder.
https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/CNC_MacroPad/code.py
## Upload the Code and Libraries to the Feather RP2040
After downloading the Project Bundle, plug your Feather RP2040 into the computer's USB port with a known good USB data+power cable. You should see a new flash drive appear in the computer's File Explorer or Finder (depending on your operating system) called **CIRCUITPY**. Unzip the folder and copy the following items to the Feather's **CIRCUITPY** drive:
- **lib** folder
- **code.py**
Your Feather RP2040 **CIRCUITPY** drive should look like this after copying the **lib** folder and the **code.py** file.
## How the CircuitPython Code Works
The top of the code has a dictionary called `keymap`. This dictionary has the attributes for each key on the macropad. These include the keyboard shortcut and NeoPixel color. The `axis_states` array affects the keyboard shortcuts for the rotary encoder. These shortcuts are defined in the `encoder_map` dictionary. You can edit these dictionaries to customize the code for your setup.
```python
# axis states selected with keys 9-11
axis_states = [0, "x", "y", "z"]
state = axis_states[0]
# keymap for key matrix
keymap = {
(0): (axis_states[0], (Keycode.COMMAND, Keycode.COMMA), BLUE), # SETTINGS
(1): (axis_states[0], (Keycode.COMMAND, Keycode.P), ORANGE), # SLICE MODEL
(2): (axis_states[0], (Keycode.COMMAND, Keycode.D), RED), # CLEAR BED
(3): (axis_states[0], [Keycode.T], GREEN), # MOVE
(4): (axis_states[0], [Keycode.S], AQUA), # SCALE
(5): (axis_states[0], [Keycode.R], BLUE), # ROTATE
(6): (axis_states[0], [Keycode.M], AQUA), # MIRROR
(7): (axis_states[0], [Keycode.E], PURPLE), # SUPPORT BLOCKERS
(8): (axis_states[0], [Keycode.I], PINK), # TABS
(9): (axis_states[1], None, RED), # SET X-AXIS STATE
(10): (axis_states[2], None, GREEN), # SET Y-AXIS STATE
(11): (axis_states[3], None, BLUE), # SET Z-AXIS STATE
}
# keymap for encoder based on state; pos = [0], neg = [1]
encoder_map = {
("x"): ([Keycode.RIGHT_ARROW], [Keycode.LEFT_ARROW]),
("y"): ([Keycode.UP_ARROW], [Keycode.DOWN_ARROW]),
# ("z"): ([Keycode.W], [Keycode.S]),
}
```
Next the key matrix is setup using a `KeyMatrix`. The `key_to_pixel_map()` function maps the NeoPixels to their key in the matrix. The rotary encoder is instantiated using `rotaryio`.
```python
# make a keyboard
kbd = Keyboard(usb_hid.devices)
# key matrix
COLUMNS = 3
ROWS = 4
keys = keypad.KeyMatrix(
row_pins=(board.D12, board.D11, board.D10, board.D9),
column_pins=(board.A0, board.A1, board.A2),
columns_to_anodes=False,
)
# neopixels and key num to pixel function
pixels = neopixel.NeoPixel(board.D5, 12, brightness=0.3)
def key_to_pixel_map(key_number):
row = key_number // COLUMNS
column = key_number % COLUMNS
if row % 2 == 1:
column = COLUMNS - column - 1
return row * COLUMNS + column
pixels.fill(OFF) # Begin with pixels off.
# make an encoder
encoder = rotaryio.IncrementalEncoder(board.D24, board.D25)
last_position = 0
```
## The Loop
The loop consists of two parts: monitoring the rotary encoder and monitoring the key matrix. The rotary encoder is controlled by keys 9, 10 and 11 in the matrix. These keys select the `axis_states` index to control either the x, y or z axis. Depending on which axis is selected, the rotary encoder will send its defined keycode from the `encoder_map` dictionary; or in the case of the z axis a mouse scroll.
```python
while True:
# poll for key event
key_event = keys.events.get()
# get position of encoder
position = encoder.position
# if position changes..
if position != last_position:
# ..and it increases..
if position > last_position:
# ..and state is x:
if state is axis_states[1]:
kbd.press(*encoder_map[state][0])
# ..and state is y:
if state is axis_states[2]:
kbd.press(*encoder_map[state][0])
# ..and state is z:
if state is axis_states[3]:
mouse.move(wheel=-1)
# ..and it decreases..
if position < last_position:
# ..and state is x:
if state is axis_states[1]:
kbd.press(*encoder_map[state][1])
# ..and state is y:
if state is axis_states[2]:
kbd.press(*encoder_map[state][1])
# ..and state is z:
if state is axis_states[3]:
mouse.move(wheel=1)
# print(position)
# release all keys
kbd.release_all()
# update last_position
last_position = position
```
The `keypad` module monitors the key matrix for events. If keys 0-8 are pressed, then their keyboard shortcut is sent over USB HID. If keys 9-11 are pressed, then their NeoPixel remains lit and an axis is selected for the rotary encoder to control.
```python
# if a key event..
if key_event:
# print(key_event)
# ..and it's pressed..
if key_event.pressed:
# ..and it's keys 0-8, send key presses from keymap:
if keymap[key_event.key_number][0] is axis_states[0]:
state = axis_states[0]
kbd.press(*keymap[key_event.key_number][1])
# ..and it's key 9, set state to x
if keymap[key_event.key_number][0] is axis_states[1]:
state = axis_states[1]
pixels[key_to_pixel_map(10)] = OFF
pixels[key_to_pixel_map(11)] = OFF
# ..and it's key 10, set state to y
if keymap[key_event.key_number][0] is axis_states[2]:
state = axis_states[2]
pixels[key_to_pixel_map(9)] = OFF
pixels[key_to_pixel_map(11)] = OFF
# ..and it's key 11, set state to z
if keymap[key_event.key_number][0] is axis_states[3]:
state = axis_states[3]
pixels[key_to_pixel_map(9)] = OFF
pixels[key_to_pixel_map(10)] = OFF
# turn on neopixel for key with color from keymap
pixels[key_to_pixel_map(key_event.key_number)] = keymap[key_event.key_number][2]
# ..and it's released..
if key_event.released:
# if it's key 0-8, release the key press and turn off neopixel
if keymap[key_event.key_number][0] is axis_states[0]:
kbd.release(*keymap[key_event.key_number][1])
pixels.fill(OFF)
```
