# BluePill handwired
Keyboards using a BluePill controller (generic Chinese STM32F103C8T6) and based on the [KC64 of Xydane](https://github.com/Xydane/qmk_firmware).
Keyboard Maintainer: [FPazos](https://github.com/fpazos), but I hope to leave the project in better hands.
Hardware Supported: Bluepill STM32F103C8T6
Hardware Availability: Everywhere
Make example for BluePill70 (after setting up your build environment):
make handwired/bluepill/bluepill70:default
See [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) then the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information.
Read everything before using it.
## Introduction
First of all thanks to [Xydane](https://github.com/Xydane) at [GeekHack](https://geekhack.org/) for his advice and his repository, without it you couldn't be reading this.
That's was an attempt to create a firmware using an STM32F103C8T6, and in a "future", also developing a revision for split keyboards. But...
As I'm mainly a web developer I didn't even get to debug the controller, not to speak about ChibiOS. So I just structured everything, created a working 70% layout and leave the project to someone with more knowledge and patience.
## Resistor fix
If you want to use the Bluepill USB port, it's very likely that you need to solder a 1.8 kΩ between PA12 and 3.3V. That depends on the PC's motherboard but I needed, more info [here](https://wiki.stm32duino.com/index.php?title=Blue_Pill).
## No bootloader
Neither Xydane or I used the bootloader, the code for it is commented and you can use it if you want. I didn't achieve to run it and just used a serial programmer (FTDI, ST-LINK).
## Adding layouts and revisions
If you want to create new layouts just add them to the keymaps folder. If you prefer to develop a more complex revision just copy the bluepill70 folder, rename it and create a new keymap in /keymap.c (I tried to divide the project even more but it didn't worked).
## Pinout
That's the pinout;
A5 A15 A10 A9 A8 B15 B14 B13 B12 B11 B10 B1 B0 A7 A6
B9 ESC| F1 | F2 | F3 | F4 | F5 | F6 | F7 | F8 | F9 | F10| F11| F12| PSC| PGU| PGD
B8 GRA| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 0 | ' | ¡ | BCKS | DEL
B7 TAB| Q | W | E | R | T | Y | U | I | O | P | ` | + | | HOM
B6 CAP| A | S | D | F | G | H | J | K | L | Ñ | ´ | Ç | ENTER | END
B5 LSI| < | Z | X | C | V | B | N | M | , | . | - | RSHIF | UP | FNT
A4 LCT| WIN| ALT| ESPACE | ALG| FN | RCT| LEF| DOW| RIG
And the wiring:
ISO
ANSI
It also uses:
PC13: Caps Lock led.
Backlight dual color leds, my version is for common anode that's more common, for leds with common anode just replace the palSetPad with palClearPad and viceversa.
PA1: Backlight color A.
PA0: Backlight color B.
