Description
3x3 Macro Keypad
Simple 3x3 Macro Keypad, I made some time ago using CherryMX switches, some SK6812 Mini-e RGB LEDs and a small 0.91" OLED display.
You can replace switch 1 (S1) with an rotary encoder if you want.
Since it uses an Arduino ProMicro - ATmega32u4 chip, you can program the this macro keypad with Arduino IDE or via QMK Toolbox.
However, if you use QMK you won't have OLED functionality.
I attached bellow, a small sketch for Arduino IDE with a code example (please be sure you have all the libraries required). The sketch is based on the awesome work of Ryan Bates from retrobuiltgames.
You can use an external 2004 LCD display as well, using the extra I2C connector.
If you have any questions please let me know.
! Also attached Gerber files for TOP and a BOTTOM plates (check Circuit diagrams and Schematics section). You can order those as regular PCBs.
BE CAREFUL !
DO NOT SOLDER THE PRO MICRO ON TOP OF THE PCB!
YOU HAVE TO SOLDER THE PRO MICRO ON THE BACK OF THE PCB WITH THE CONNECTOR FACING UP.
Code
Sample Sketch. Adapt it to your needs.

/******************************************************************* v 3.4.3 - 26.05.2021 change log: refactored the color based filling patterns function by adding params - [ setColorsModeHUE( long, int) ] added a 5th MODE - AUTOMATICALLY MOUSE MOVEMENT - YOU KNOW WHAT FOR !!! v 3.4.2 - 25.05.2021 change log: added color based filling patterns for Photoshop and Excel mode added a rainbow filling effect for keypad mode v 3.3 - 22.05.2021 change log: update the display order of function's numbers to match the keypad numbers. [in the switch function keys are numbered from top left (1) to bottom right (9), but in order to match the classc keypad i changed the way they appear n the screen from bottom left (1) to upper right (9)] in switch 1 2 3 on display 7 8 9 4 5 6 4 5 6 M 6 7 9 M 1 2 3 Pro Tips: =============== Keyboard Control================================================================================ Keyboard.write(); Sends a keystroke to a connected computer. This is similar to pressing and releasing a key on your keyboard. Will send a shift command if applicable. Example: Keyboard.write('K') will automatically do SHIFT + k. Can also accept ASCII code like this: //Keyboard.write(32); // This is space bar (in decimal) Helpful list of ASCII + decimal keys http://www.asciitable.com/ Keyboard.press(); Best for holding down a key with multi-key commands; like copy/ paste This example is [ctrl] + [shift] + [e] //Keyboard.press(KEY_LEFT_CTRL); //Keyboard.press(KEY_LEFT_SHIFT); //Keyboard.press('e'); //delay(100); Keyboard.releaseAll(); Keyboard.print(); Sends a keystroke(s) Keyboard.print("stop using aim bot"); // types this in as a char or int! (not a string)! Keyboard.println(); Sends a keystroke followed by a newline (carriage return) Very practical if you want to type a password and login in one button press! SOMETIMES, applications are coded to recognize Keyboard.press() and not Keyboard.write() and vice versa. You might have to experiment. =============== Mouse Control================================================================================ Mouse.move(x, y, wheel); Moves the mouse and or scroll wheel up/down left/right. Range is -128 to +127. units are pixels -number = left or down +number = right or up Mouse.press(b); Presses the mouse button (still need to call release). Replace "b" with: MOUSE_LEFT //Left Mouse button MOUSE_RIGHT //Right Mouse button MOUSE_MIDDLE //Middle mouse button MOUSE_ALL //All three mouse buttons Mouse.release(b); Releases the mouse button. Mouse.click(b); A quick press and release. **********************************************************************************************************/ // -------------------------------------------------------------- // Standard Libraries // -------------------------------------------------------------- // Library with a lot of the HID definitions and methods // Can be useful to take a look at it see whats available // https://github.com/arduino-libraries/Keyboard/blob/master/src/Keyboard.h // This library is for interfacing with the 3x3 Matrix // Can be installed from the library manager, search for "keypad" // and install the one by Mark Stanley and Alexander Brevig // https://playground.arduino.cc/Code/Keypad/ const byte ROWS = 3; //three rows const byte COLS = 3; //three columns char previousPressedKey; boolean hasReleasedKey = false; //use for button Hold mode.
