Zhihuijun's new work: Hanwen smart keyboard with FOC force feedback knob, multi-function, modular mechanical keyboard (schematic, firmware, etc.)

Hanwen Smart Keyboard is another new product of Zhihui Jun. It is a multi-functional and modular mechanical keyboard designed according to his own needs. Currently, the schematics, firmware, etc. are open sourced. Due to some small bugs with flying wires on the PCB, they have been fixed and need to be re-prototyped and verified before development. For video demonstrations of the work, you can go to Zhihuijun’s B station account to view: https://www.bilibili.com/video/BV19V4y1J7Hx

The keyboard adopts a modular design. The multi-functional scene interaction module on the left can be replaced with various custom components. The default one is a Dynamic component with an e-ink screen and FOC force feedback knob ; the keyboard uses a dynamic component developed by Zhihui Jun himself. The keyboard firmware and module firmware of the ARM Cortex-M chip; the keyboard body uses a shift register to implement an optimized key scanning circuit ; the module and the keyboard body can be used alone, or they can communicate and call each other through the serial port protocol.

In the download package below, the open source information includes:

    - 10 PCB design source files of Hanwen font hardware design, providing the file format of Lichuang EDA Professional Edition
    - Shell design structure file
   - Firmware source code of the keyboard body (relatively complete )
    -Dynamic component firmware source code (completed framework, more APP extension WIP)
    -Keyboard secondary development SDK (under development)
