Detailed Description

Configuration and management of SPIRIT VCO-RCO calibration.

This module allows the user to set some parameters which deal with the oscillators calibration. The state machine of Spirit contemplates some optional calibrating operations in the transition between the READY and the LOCK state. The user is allowed to enable or disable the automatic RCO/VCO calibration by calling the functions SpiritCalibrationVco() and SpiritCalibrationRco(). The following example shows how to do an initial calibration of VCO.

Example:

  uint8_t calData;

  SpiritCalibrationVco(S_ENABLE);
  SpiritCmdStrobeLockTx();

  while(g_xStatus.MC_STATE != MC_STATE_LOCK){
      SpiritRefreshStatus();
  }

  calData = SpiritCalibrationGetVcoCalDataTx();
  SpiritCalibrationSetVcoCalDataTx(calData);

  SpiritCmdStrobeReady();
  SpiritCalibrationVco(S_DISABLE);

Similar operations can be done for the RCO calibrator.
