# 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.

## 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).

|

|
|
|
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. |
