For the first time to create an ink screen, I'm thinking of adding the Pomodoro Technique to the traditional WIFI clock, making it more powerful instead of providing time and weather information only, and looking for a way to help people increase productivity and become your best, most productive self at work. when using the RedClock.

My RedClock is now supported to implement:

  • Display time and weather info through ink screen.
  • One button can switch into Pomodoro Technique
  • Obtain temperature and air pressure info via the external air pressure sensor lps22hh and passes to ink screen
  • Time, weather, temperature, and air pressure information also supports simultaneously display on the device IP when there is network access to ART-Pi.

Development Environment:

Hardware: ART-Pi 、LPS22HH、SSD1619

RT-Thread inside: V4.0.3

Development Tool:

  • Compiling Tool: arm-none-eabi-gcc、 arm-none-eabi-binutils
  • Editing Tool: vim
  • Burning & Debugging Tool: openocd 0.10+ dirty、kermit、telnet、gdb

Hardware Development Tool：Kicad（RedClock Expansion Board Development Tool）
