      1 # QMK-based firmware for Sejin EAT-1010R2 keyboard
      2 
      3 * Keyboard Maintainer: [DmNosachev](https://github.com/DmNosachev)
      4 * Hardware Supported: Sejin EAT-1010R2 (membrane keyboard, Sejin
      5 Futaba-mount dome, Asian 101 ISO layout), Blue/Black Pill STM32F103 MCU 
      6 oard. Alternatevely you can use any MCU which is supported by QMK and
      7 has 27 or more IO pins
      8 
      9 Make example for this keyboard (after setting up your build environment):
     10 
     11     make handwired/sejin_eat1010r2:default
     12     
     13 Flashing example for this keyboard:
     14 
     15     make handwired/sejin_eat1010r2:default:flash
     16 
     17 
     18 See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools)
     19 and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide)

     22 
     23 ## Additional hardware
     24 * 16 and 8 pin 2.54mm (0.1'') FPC connectors. They can be found at
     25 Aliexpress for 2–3 USD for 10pcs. Two 8 pin connectors can be glued
     26 together as a replacement for 16 pin.
     27 * Three 5mm LEDs and current limiting resistors (150–300Ω, depending on
     28 LED specs). This keyboard has exactly the same spacing between LEDs as
     29 IBM Model M, so a corresponding PCB can be used after adding resistors.
     30 
     31 ## Membrane
     32 Sejin EAT-1010R2 has 16x8 matrix. There are 16 and 8 pin flex connectors
     33 from membrane sheets. Solder FPC connectors to devboard (numbering from
     34 left to right, see *matrix_pins* in info.json file).
     35 
     36 ## Bootloader
     37 Burn [STM32duino bootloader](https://github.com/rogerclarkmelbourne/STM32duino-bootloader)
     38 to Blue Pill board.
     39 
     40 There are several ways to get into the bootloader:
     41 * STM32duino bootloader waits for 3 seconds in DFU mode before jumping to application.
     42 You just have to start the flashing process, then connect the USB.
     43 * This firmware is configured with [bootmagic feature](https://docs.qmk.fm/#/feature_bootmagic).
     44 Hold the ESC key down when plugging the keyboard in to trigger the bootloader.
     45 
     46 ## Troubleshooting
     47 There is *debug* layout which has mapping for every matrix position and
     48 prints column and raw numbers to console (hid_listen or QMK toolbox).
