Quickpin

Quickpin helps devs quickly translate pinouts between boards of similar footprint. This lets you write a single kb.py that can be swapped between microcontrollers with only a single line change and less mistakes.

Supported footprints/boards

  • Pro micro footprint
    • Sparkfun Pro micro RP2040
    • Boardsource Blok
    • Nice!nano

Example

In this example, we are converting a Boardsource 3x4 from a hard pinned nice!nano to a controller agnostic pinout.

row_pins = (board.P1_15, board.P0_02, board.P0_29)
col_pins = (board.P0_09, board.P0_10, board.P1_11, board.P1_13)

Converts to the following. Notice that nice_nano can be subbed for boardsource_blok or sparkfun_promicro_rp2040, or any other board sharing this pinout.

from kmk.quickpin.pro_micro.nice_nano import pinout as pins

row_pins = (pins[16], pins[17], pins[18])
col_pins = (pins[12], pins[13], pins[14], pins[15])

Porting from AVR pro micro

An additional added convenience for translating from other firmwares with AVR pro micros has also been added to speed up porting.

from kmk.quickpin.pro_micro.nice_nano import pinout as pins
from kmk.quickpin.pro_Micro.avr_promicro import translate as avr

row_pins = (
pins[avr['F7']],
pins[avr['F6']],
pins[avr['F5']],
)
col_pins = (
pins[avr['B6']],
pins[avr['B2']],
pins[avr['B3']],
pins[avr['B1']],
)

Adding boards to quickpin support

Quickpin format is simply a list of pins in order of all through hole pins, going anticlockwise starting at the top left. The orientation should be with the chips facing toward you, with USB facing the top. If this isn't appliable, or otherwise is not true, it should be stated in a comment in the file. Any pin that is not addressable in software should be left as None to fill the space, and align pins correctly for all boards. All boards should be stored in kmk/quickpin/<footprint>/boardname.py.
