Two small fixes:

  • Sparrow 4" has TCXO temperature sensor, so enable it on that type of board.
  • TCXO state stored in EEPROM was read from EEPROM on boot but then zeroed in memory.

TCXO settings are saved properly to EEPROM. Unfortunately on boot
EEPROM was read first and then this code zeroed these.

That caused TCXO deactivation and unit setting back to Celsius
regardless of what settings were saved in EEPROM.
