Programable Button Box with encoder and screen

prusaprinters

<p>This is a Button Box with 17 programable buttons as well as a rotary encoder and an OLED screen. This box is very customizable using some simple python code. You can program it to send individual key commands or program macros to send with the push of a button.</p><p>I used Thonny to put it all together but you can really use anything including a text editor like Notepad++.</p><p><strong>Attn: You will also need the file font5x8.bin. </strong>Printables will not let me upload a bin file so I am including a link to the Git page. <a href="https://github.com/adafruit/Adafruit_CircuitPython_framebuf/blob/main/examples/font5x8.bin">https://github.com/adafruit/Adafruit_CircuitPython_framebuf/blob/main/examples/font5x8.bin</a></p><p>The font5x8.bin file should be placed in the same spot as your code.py file. See font5x8_file_placement.pdf for a screenshot.</p><p>&nbsp;</p><p><strong>Printing:&nbsp;</strong></p><p>Since I didn't need a lot of detail, I printed at .3 layer height in PETG for the case and .2 for the knob.</p><p>&nbsp;</p><p><strong>Hardware:</strong></p><p>1 - Raspberry Pi Pico</p><p>1 - KY-040 Rotary Encoder</p><p>1 - .96in. SSD1306 compatible display. I used this one: https://a.co/d/by2PZQ6</p><p>16 - keyboard switches. I used these: <a href="https://a.co/d/dBdjb3q">https://a.co/d/dBdjb3q</a></p><p>16 - keycaps. I used some that I had laying around but any will work as long as they're compatible with the switches you choose.</p><p>&nbsp;</p><p><strong>Code:</strong></p><p>I've added all of the Python code that I used except the font5x8.bin file which you will need to get from Adafruit's Github since Printables won't let me upload it here.</p><p>You can modify any of the keys by replacing the command with any (single or combination) of commands from the attached Keycode.py file.</p><p>The current setup has the rotary encoder setup to control Volume up/down and the encoder button is setup for Mute/Unmute.</p><p>I also setup the keys to link to numbers and symbols but they can be easily changed to any combination of the keycodes found in keycode.py</p><p>&nbsp;</p><p><i>*** Important note ***</i></p><p><i>You will need to make sure you have included all of the module files in a folder named \lib</i></p><p><i>within that folder you will also need to have a folder named adafruit_hid.
