# GD32vf103 vga ps2keyboard Controller
## Foreword
This is a small project for gd32vf103,an excelent RISC-V microcontroller .However , there are not many projects written by this processor .I decide to share the debugging process and how it works here.This is just a basic demo ,later I'll try to prefect this project and add more features .
## PS2 Keyboard
PS2 keyboard interface was widely used a few years ago(I'm still using ps2 keyboard and mouse now) and its sequence in time is easy ,so I decide to use it as human-computer interaction.
### ps2 interface
We only need to use 4of the 6lines to drive the ps2 keyboard they are
>PS2PIN -> GD32vf103PIN
4 -> 5v
3 -> GND
5(clk)->PA0
1(data) -> PA3
### ps2 sequence in time
# VGA
>VGAPIN -> GD32VF103
HSYNC ->PB0
VSYNC -> PB6
GREEN->PA7
