James Young a03aa301de Remove Full Bootmagic (#13846 ) * disambiguate Bootmagic rules in keymaps The files edited by this commit were added at a point in time where `BOOTMAGIC_ENABLE = yes` enabled full Bootmagic. This commit edits the files to specify that full Bootmagic is intended. * remove BOOTMAGIC_ENABLE=full setting * unify commented BOOTMAGIC_ENABLE rules in keyboards Explicitly sets `BOOTMAGIC_ENABLE = no` in keyboards where the rule was commented out. Command: ``` find keyboards/ -type f -name 'rules.mk' -and -not -path '/keymaps/' -exec sed -i -e 's;#[ \t]\(BOOTMAGIC_ENABLE\)[ \t=]\+\([a-zA-Z]\+\).;\1 = no # Virtual DIP switch configuration;g' {} + ``` * remove commented Bootmagic rules from keymap/user level Command: ``` find keyboards/ layouts/ users/ -type f -name 'rules.mk' -exec sed -i -e '/#.\(BOOTMAGIC_ENABLE\)[ \t=]\+\([a-z]\+\)./d' {} + ``` * update keyboard BOOTMAGIC_ENABLE rule formatting Sets the formatting of BOOTMAGIC_ENABLE rules to `BOOTMAGIC_ENABLE = [value]`, without the inline comments (which will be replaced later). Command: ``` find keyboards/ -type f -name 'rules.mk' -and -not -path '/keymaps/' -exec sed -i -e 's;\(BOOTMAGIC_ENABLE\)[ \t=]\+\([a-z]\+\).;\1 = \2;g' '{}' + ``` update keyboards' BOOTMAGIC_ENABLE settings Updates keyboard `rules.mk` files to use `BOOTMAGIC_ENABLE = lite` where `BOOTMAGIC_ENABLE = full` was being used.

Commands: ``` find keyboards/ -type f -name 'rules.mk' -and -path '/keymaps/' -exec sed -i -e 's;\(BOOTMAGIC_ENABLE[ \t=]\+\)full;\1lite;g' '{}' + find layouts/community/ users/ -type f -name 'rules.mk' -exec sed -i -e 's;\(BOOTMAGIC_ENABLE[ \t=]\+\)full;\1lite;g' '{}' + ``` * remove and replace inline comments in keyboards and keymap/user files Removes and replaces the inline comments, which have been updated to read `Enable Bootmagic Lite`.

This commit corrects the filenames of the affected files. * update renamed file with new rule formatting * update QMK's template files Updates QMK's `rules.mk` templates to use the new inline comment. * update QMK Docs - remove documentation of full Bootmagic - update links to Bootmagic Lite doc - add doc for Magic Keycodes * rules.mk patch for coarse/ixora and coarse/vinta		2021-08-06 23:59:56 -07:00

Pinout

Challenges

I'm very happy with the result, but at some point Proton C was driving me nuts.

I did a lot of trial and error during assembly & programming. There were a lot of yet undocumented caveats, so I'll outline them here so that you guys can avoid the same issues I had.

Matrix & encoders

Although this is a 48-key board with a 12-col & 4-row matrix, I've decided to add an extra row above the first one to make my matrix 12x5 and wire encoders' push buttons as 2 extra keys, thus making it a total of 50 (12x4 + 2 encoders). I used 2 columns (9 & 12) for those buttons.

So, a first row actually has 2 buttons on columns 9 & 12 (because encoders are located near those columns). Encoders' push buttons are also configured via QMK's keymap.

Check out the d48.h & config.h for pins used & keymap macro definition.

I²C/OLED

Most of the stuff worked out of the box, except me choosing the right pins for my OLED.

On the Proton C pinout, there are 3 labels for I²C and for some reason there are 2 pairs of SDA/SCL for I²C¹ channel: B8/B9 (rear left side) and B6/B7 (rear right side). I'm not sure if this is a mistake or if I was doing something wrong. So initially I picked B8/B9 which were not working. When I switched to B6/B7, things worked like a charm. Later I used B9 for matrix row. No issues so far.

Oh, and by the way, while using B8/B9, keyboard was sometimes swallowing quick keypresses. I believe this was due to I(2)C timeouts (because incorrect pins were used for OLED).

Buzzer

It turns out once you switch on AUDIO_ENABLE, you cannot use A4 & A5 because they interfere with the buzzer. My guess is that buzzer uses DAC channels (not sure why both).

I couldn't find this in documentation. Honestly, Proton C has almost zero documentation and this was the biggest challenge. Anyway, apart from almost going crazy from those challenges, I really liked it!

RGB

I used pin A15 for my WS28128 RGB strip.

D1307 real-time clock

Connecting DS1307 RTC was a piece of cake: same I² pins as OLED (SDA/SCL), GND to GND and power to Proton C VUSB pin (5v).

Other issues

B5 could not be used for matrix.
TAP_CODE_DELAY had to be increased to 10 to fix tap_code(KC_VOLU/KC_VOLD) calls being swallowed in encoder callback.
Be extremely attentive about the pinout: keep in mind that the official Proton C pinout displays the rear of the board, not the front. Being used to front pinouts, I ended up soldering entire matrix to the wrong side, so I had to desolder every wire and connect it to the opposite side.

Conclusion

I had a lot of fun. The layout was inspired by the Planck THK. Feel free to ask any questions!
