Wire keys directly to pins
Hello,
There are some cases where you have so few keys (ej: a 9 key macro pad) that it's way easier to attach each key to a single pin than building a matrix. Is there a way to specify this on your tool ?
Thanks in advance
FInally I figured it out I'm compiling here the proper steps so anyone else can follow them easily. The scenario is as follows: you have an arduino pro micro, with enough pins for your 3x3 macro keypad, so you want to save some diodes and don't use a matrix.
- The first step is to create a 9x1 layout at keyboard-layout-editor. You can take this one as [[example|http://www.keyboard-layout-editor.com/#/gists/63503f3118a7a71aadbdfb23e743716c]]
- Then you want to copy the info at the raw data section, and paste (or import it) into https://kbfirmware.com/
- Probably the most confusing part is the pinout. Leave the rows at B0, which seems to mean ground.
- Set the pins on the columns making use of this this schema:
just remove the letter P and you will have the correct pin. EJ: PD1 -> D1 which is labeled as 2 on the arduino
- Download the .hex file and burn it using QMK toolbox
DONE! It is working fine for me
