Introduction

Arudino APRS tracker is based on Arduino UNO with next periherals:

Requirements

  • Minimum: Arduino UNO with 2k SRAM, 32k FLASH
    • may require some manual libraries optimization, such as buffer size decrease
    • or different screen, PCD8544 requires 500 bytes of RAM for the buffer
  • Recommended: Arduino MEGA with 8k SRAM
    • NB! needs some tweaks in LibAPRS internals

Dependencies

Supported user operations

  • Rotary encoder rotation iterates over transmit heuristics selection, such as periodic transmit every 1 minute, 2 minutes, 500 meters, etc.
  • Short encoder release activates current heuristic if it is different from the current one or iterates over different APRS SSIDs
  • Long encoder release forces current position to be sent out
You can’t perform that action at this time.
