112 LED Panel Driver

112 : LED Panel Driver


How it works

  • The circuit updates a P10 16x16 LED display module
  • It initially displays the string TT03P5
  • It provides a 1.2Mbaud uart input to
    • paint pixels
    • erase pixels
    • clear the display
    • change the displayed colour
  • Functionality is limited by resource availability
    • single colour at once
    • no double buffer, updates may have artifacts
  • Mode pin to allow for 2 different clocking patterns

How to test

  • Connect the display module as per the outputs
  • Connect the uart
  • Power on and see the TT03P5 text
  • If the display is swapped by quadrant change the mode pin
  • Use the script(s) in the software directory to control the display
