BluePill handwired

Keyboards using a BluePill controller (generic Chinese STM32F103C8T6) and based on the KC64 of Xydane.

Keyboard Maintainer: 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 the build environment setup and the make instructions for more information. Brand new to QMK? Start with our Complete Newbs Guide.

Read everything before using it.

Introduction

First of all thanks to Xydane at GeekHack 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.

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

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.
