*** Step 2: Create the columns
The next step is to create the columns by soldering the diodes. There are two options for
- soldering the diodes. The end where that color-mark is denotes the direction of the diode. The
- way these diodes are directed is crucial for the algorithm that detects the
- key-press. Detecting the key-press can be done in two ways, row- or column-driven.
-
- These following sketches are supposed to make the two "driving"-options the ergodox-firmware
- has more clear.
+ soldering the diodes, all heading towards the switch or all heading away from the
+ switch. These two ways are called "row-driven" or "column-driven" and here again it is
+ cruciual for the firmware and the actual wiring to be on the same page.

- Luckily in our firmware "ergodox-firmware" we have the option that adapts to that. However if
- you want to try and use the "tmk_keyboard" firmware which seems to be also interesting you
- want to wire the diodes the other way. This way the "columns are driving". As a side note, if
- I understand it correctly the tmk_keyboard firmware thinks of rows as columns and the other
- way around.
-
- The tmk_keyboard firmware could also be used for this kind of wiring, but it would have to be
- rewritten, maybe in a beautiful way, such that it can also "drive rows". However I didnt go
- ahead and perfom that rewriting, so I had to stick with the "ergodox-firmware". In retrospect
- I'd wish I had wired the diodes the other way around.
+ If you want to try and use the "tmk_keyboard" firmware which seems to be also interesting you
+ want to wire the diodes in the according way (check whether the tmk_keyboard firmware expects
+ a row-driven or a column-driven setup).
- This first picture doesnt show how the 6 thumb-keys are actually individually connected to the 6
- main columns, but you can see very clearly that the diodes are all wired in the same direction.
