DolphinV4 Calibration

Each module based on the EO3100I chip is already calibrated in the EnOcean production. The calibration values are stored in the Configuration area. In case these values are lost or they are for some reason not available (for instance for chip customers who are working with uncalibrated chips) using the calibration utilities the values can be newly calibrated.

NOTE:
If the configuration area values were for some reason lost, be sure to check for cfg backup in the program directory before using the calibration utilities, for example: c:\Program Files\EnOcean\DolphinSuite\Backup directory!

When using calibration please backup the MOD area with the following command: 

eopx2 –read –fmod modbackup.hex

For more information about the configuration area read the EO3100I_API manual Chapter Flash Architecture\Configuration Area.

For calibration choose the calibration steps you want to perform and click "Execute Calibration".

Timer and Temperature Calibration

The calibration of the timers and the temperature senor is quite easy. After you have clicked on "Execute Calibration" the calibration firmware automatically calibrates the timer. If you also selected temperature calibration you will be prompted to enter the current temperature. With this value the calibration firmware is able to perform the calibration.

Radio calibration

The frequency calibration makes it possible to calibrate the crystal ppm errors. For this calibration procedure a Spectrum Analyser is needed which is connected directly with the module/chip through an RF cable.

How to use:
  1. connect your spectrum analyser with the HF cable to the module/chip
  2. configure the spectrum analyser in the following way
  3. the calibration utility will download a hex file which sends an uncalibrated continuous wave (CW) signal
  4. find the peak of the CW signal and enter the frequency to the calibration routine
  5. after the value is entered the program calculates the correction factor and writes it to the configuration area
  6. then a calibrated CW will be transmitted
