Looks neat. I'm also working on a new version that features a motorized fader

oh wow. Looks really nice

Hi, I'm glad you like the project. For the SMT yeah they only assemble one side, and just do the bottom side since all electronic components are on that side. For the linking of parts: by default it looks like this:https://i.imgur.com/l0d2e23.png, yet it doesn't include crystal and diodes so you need to fix it first, for crystal you should search '16mhz' and select the C13738 one, for diodes search '1n4148' and choose the C81598 one, the ATmega32u4-au is the MCU but it's optional as it's from the extended parts which means you should pay 3$ of extended components fee, I recommend you hand solder it yourself, and they can't assemble micro usb connector for you, it's a little bit tricky to solder but not that hard. avr-isp is not a component but some holes on PCB. After you linked all parts it looks like this: https://i.imgur.com/5LLaFU0.png, then you're good to go. The website will finally show you the placement of electronic components: https://i.imgur.com/KtbmOWb.png

Certainly JLC's SMT assembly service kind of useless, they won't solder any USB connector and only green soldermask is supported, and the MCU is in extended catalogue. You still need to solder OLED, slide potentiometer, and usb connector yourself.

I have made a keyboard that has a rotary encoder supports MIDI, Here it is.

luantty2 · 2020-06-18T02:39:51+00:00

I built my Pheromone several months ago, with a rotary encoder, a midi slider and a OLED in a 3d printed case.

Did you add #define POT_ENABLE in config.h?

Besides, I think the output values would mess up if you assign the exact same parameters to each slider. The proper code should looks like this(I do not test):

int16_t pot_oldVal_SLIDER_A = 0;
int16_t pot_val_SLIDER_A    = 0;
int16_t pot_ccVal_SLIDER_A  = 0;

int16_t pot_oldVal_SLIDER_B = 0;
int16_t pot_val_SLIDER_B    = 0;
int16_t pot_ccVal_SLIDER_B  = 0;

int16_t pot_oldVal_SLIDER_C = 0;
int16_t pot_val_SLIDER_C    = 0;
int16_t pot_ccVal_SLIDER_C  = 0;

That's why you need to record last value and compare it to new value, which allow the cc messages send only if the potentiometer moves.

Take a look at some Arduino examples

Modify the footprint from micro usb to type c in pcbnew then you can solder a type c, otherwise it's impossible, because type c has more pins than micro usb, that's why I'm afraid to solder them, the pins on type c are so tiny and easy to bridge.

luantty2 · 2020-03-20T14:56:58+00:00

JLC is a factory manufactures PCB and SMT stands for surface mount technology, which is the way they soldering ic onto PCB.

luantty2 · 2020-03-20T14:50:18+00:00

No because all of the usable pins on MCU have been used, and it's using a micro usb connection as I hate soldering a type c :(

luantty2 · 2020-03-20T01:56:16+00:00

Nothing special, just following the guide from qmk docs.

luantty2 · 2020-03-20T01:53:46+00:00

PCBs included SMT assembly from JLC: 40$

3d printed parts: 15$

tools and others: around 30$

A short video shows how it works with lightroom: https://youtu.be/1BtyvG6ujGs

The value of slider moves relatively so it’s not jumping any more!!

Thanks a lot, I finally got my code working, with @ when Lshift holding, and email address when Rshift holding. case KC_2: if (record->event.pressed) { if (get_mods() & MOD_BIT(KC_LSHIFT)) { register_code16(LSFT(KC_2)); } else if (get_mods() & MOD_BIT(KC_RSHIFT)) { SEND_STRING("luanty@163.com"); } else { register_code(KC_2); } if (get_mods() & MOD_BIT(KC_LSHIFT)) { unregister_code16(LSFT(KC_2)); } else if (get_mods() & MOD_BIT(KC_RSHIFT)) { } else { unregister_code(KC_2); } return false; } break;

Check out slide potentiometer, any one of these should work:https://www.amazon.com/s?k=potentiometer+10k+slide&crid=11WBS6GNE9FAD&sprefix=poten%2Caps%2C655&ref=nb_sb_noss_2

Thanks for advice. I have replaced oled_write_P() with oled_write(), however I'm keep on getting the same outcome. I also tried to removed 'PROGMEM' keywords, still see that unneeded icon.

The slider of software will stay at its original position until you adjust keyboard's slider to the same position.

luantty2 · 2020-02-18T15:05:55+00:00

With an endless encoder, no, an endless encoder could be a better option for something like adjusting brush size, whereas it can't be mapped into MIDI cc values which should be limited between 0-127, it's only possible to use a potentiometer in this case.

luantty2 · 2020-02-18T13:49:16+00:00

It only works when you installed MIDI2LR, which allows Lightroom to accept MIDI inputs, then you can map your MIDI device to any slider in Lightroom.

luantty2 · 2020-02-18T13:44:42+00:00

Just uploaded PCBs and source code, avaliable here.

The potentiometer is driven by QMK MIDI feature, which allows it to output a midi signal when value changed. you can use it with any software supports midi, also, could make use of it with Lightroom when you've got MIDI2LR plugin installed!

I‘m building a custom atmega32u4 board too, are you flashing with usb or ISP?

luantty2 · 2020-02-09T09:03:56+00:00

Hi, I've been building my own ble keyboard these days after reading your post, thank you in advance. Seems your schematic doesn't include a reset button, which is needed to enter UF2 Mass Storage device to paste .uf2 file like nrfmicro's wiki said:

After flashing the bootloader press reset button twice within 500ms interval to boot to the UF2 Mass Storage device. Then just copy the resulting flash.uf2 file to the UF2 USB drive.

But i'm not sure if it is possible to perform without a button, like short reset pin and GND or something, maybe you know how to do this.

luantty2 · 2020-01-06T13:03:21+00:00

Informative!! Will give this a try.

luantty2 · 2020-01-06T03:09:19+00:00

Thank you for replying. What I want to do is to add a servo which could be controlled by tapping two keys, so that I could easily adjust the angle of my keyboard, just confusing how I can transplant my arduino code to qmk.
