Changelog for Timer V 23.9

  • Timer sends engine run time and used energy amount data of last flight to the programmer
  • propeller brake servo returns to released posotion after braking has done
  • Display changed to 1602 LCD
  • ESC throttle range set to ordinary 1000 – 2000 us
  • LED blinking modified (no blinking at “Ready to start mode”; fast blinking for 60 seconds after DT)
  • new programmable function: “model Id.” – assigning the model number to the altitude data
  • Second servo for large diameter propeller brake added
  • External EEPROM was added to programmer for saving complete altitude diagrams
  • Some functions were modified for more reliable program codes

To download altitude diagram data to computer:

  1. Connect the programmer’s Arduino to the computer
  2. Start Arduino IDE
  3. Run Serial Monitor with baund rate 9600
  4. Press a function change button on the programmer
  5. Copy the series of altitude data to Excel (the altitude values were saved in every 1 second)
