3.6.1 MPLAB Projects

The PHY Calibration Tool generates an output configuration file (Figure 3-9) that provides the required information to include in PLC projects to apply the custom calibration on MPLAB projects.
Figure 3-9. Configuration File Report
Most of the changes can be done through MPLAB MCC Configurator for the PLC PHY Coupling module.
Figure 3-10. MPLAB Code Configurator for PLC PHY Coupling Module

Modifying the configuration of the PLC PHY Coupling in MCC is the recommended method, as it will be reflected in the source code automatically by clicking the Generate button of the tool. The Table   1 table shows the correspondence between the report file definitions and the MCC PLC PHY Coupling fields.

Table 3-1. Correspondence on MCC PLC PHY Coupling Fields
SRV_PCOUP_RMS_HIGH_TBLTarget RMS values in HIGH mode for dynamic TX gain
SRV_PCOUP_RMS_VLOW_TBLTarget RMS values in VLOW mode for dynamic TX gain
SRV_PCOUP_THRS_HIGH_TBLThreshold RMS values in HIGH mode for dynamic TX mode
SRV_PCOUP_THRS_VLOW_TBLThreshold RMS values in VLOW mode for dynamic TX mode
SRV_PCOUP_DACC_TBLPLC DACC peripheral settings
SRV_PCOUP_GAIN_HIGH_TBLTX gain values for HIGH mode
SRV_PCOUP_GAIN_VLOW_TBLTX gain values for VLOW mode
SRV_PCOUP_NUM_TX_LEVELSNumber of TX levels
When pre-distortion values need to be updated, it is mandatory to modify the source files generated by the MCC directly, specifically the file config\PLATFORM\service\pcoup\srv_pcoup.h.

Depending on the platform and the protocol, the values from the PHY calibration Tool configuration file must update the associated definitions to that platform and protocol on the source file. For example:
  • If the calibration was done for the PL460-EK auxiliary branch, the definitions associated in the source file include an _AUX_.
  • If the calibration was done for a PRIME channel, the definitions associated in the source file include a _CHNx_.
  • If the calibration was done for a PRIME dual channel configuration, the definitions associated in the source file include a _2CHN_.
