Add Bluepill (stm32f103) handwired keyboard (#4126)
* Main folder
Main folder with some changes like the base layout and matrix for uploading in a future to the qmk repositorie
* First Commit
Firsts non previously commited changes:
-Changed to keyboards/handwired
-Basic credit to Xydane
-70% Layout
* Modified file structure for several keyboards
As I don't want to create several folders and overcrowd the main folders I made a few modifications to being able of configure several keyboards as revisions of the main keyboard.
Added a second variant.
Compiling tests went right but I haven't tried it on the controller.
* Starting leds
* Started dual color leds PWM functions and configs
I started to create the PWM functions and configs based on internet examples, it doesn't compile yet
* Backtraced a bit to establish and try debug before continuing the pwm
Just this, algo some doc as a new pinout image, space cadet modification to try if it works and little more
* Deleted unuseful stuff
After trying the reestructure to being compatible with several keyboards and that it worked I deleted the other keyboard.
Added space cadet shift to ISO.
Finally I couldn't debug everything and I'm getting quite frustrated to continue much more than just adding pwm leds
* Changed again Iso fix for Space Cadet
* Renamed keyboard, future pull
I just renamed the keyboard and made some simplifying changes in order to make a pull request sometime soon.
I'm too frustrated, tired and knowledge limited to achive using the PWM for leds, I didn't even get to use the debug mode...
I intend to end basic led color change using layers (if I can), document everything properly and make a pull request so other users can continue/use this project.
* Writed Readme.md file
I also corrected a previous compilation problem and ordered a bit the keymaps
* Corrected readme
* Try to add layer activated light
* Revert "Try to add layer activated light"
This reverts commit 205af820d845dab08988f329b9f062f558060220.
* Progress to fork
Coming back to work, upcoming pull
* Linked image
Corrected readme
* Some cleanning
Added images to readme, som cleaning, burning after commit.
* Almost finished (working)
Finally
* Finished bluepill firmware
Just finished and tried layer dependant led colors. Going for merge
* Deleted innecesary stuff and trailing spaces
Just as commit title said.
* Coding conventions
Just modified some files to respect coding conventions
* Deleted XXXXXX define
Checking some other PR seen this improvement
* Changes suggested on PR
Firs doing the easy changes
* More changes for the PR
-I also deleted one unused function for led toggling on matrix.c (Now it uses layer dependent baklight, algo on of on start)
-Deleted commented function on keymaps.
Right now only needs testing and all pragma replaces.
* Almost every pragma change on PR
That's almost finished, only waiting for reply due to compiling errors
* Revert "Almost every pragma change on PR"
This reverts commit 07f23aa862b370cdf0ae37d6f2130c9e9856f491.
* Revert last commit
I moddified by mistake a file from another keyboard
* Solved last pragma
Compiles fine.
Now I only need to test it, I say you if it works to include it in the main repository.

# 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).

## Pinout

|
|
|
|
|
|
|

|

That's the pinout;
|

|
|
|
|
|
|
|
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.
