Change XOSC speed and settings

Hello,

on SPC56EL60, I'm using an external 16MHz XTAL so I changed the ''XOSC Clock'' value in the configuration (default is 40MHz). I'm getting the error:

''SPC5_FMPLL0_VCO_CLK outside acceptable range (SPC5_FMPLLVCO_MIN...SPC5_FMPLLVCO_MAX)''

To solve this I have to modify SPC5_FMPLL0_IDF_VALUE and SPC5_FMPLL0_NDIV_VALUE value's that are used to calculate SPC5_FMPLL0_VCO_CLK.

These defines are code generated and I can't find them in the application config. Can you please explain how the setup the clock peripheral and keep the overide values unchanged while regenerating code?

Thank you

Hello Aurélien ,

Sorry for my late answer,

at the current time, it is not possible to configure IDF_VALUE and NDIV  in your SPC56ELxx HAL Drivers Component version by  GUI.

there is a change request about that to add this extended settings

and the group is set to FALSE:

(cf below from plugin.xml)

org.chibios.spc5.components.hal.platform.spc56elxx

<property

                           brief=''FMPLL0 Input Divider Value.''

                           default=''1''

                           editable=''true''

                           max=''15''

                           min=''1''

                           name=''IDF Value''

                           required=''true''

                           type=''unsigned''>

</property>

<property

                           brief=''FMPLL0 Multiplier Value.''

                           default=''32''

                           editable=''true''

                           max=''96''

                           min=''32''

                           name=''NDIV Value''

                           required=''true''

                           type=''unsigned''>

 </property>

#define SPC5_FMPLL0_IDF_VALUE               ${conf.instance.initialization_settings.fmpll0_settings.idf_value.value[0]} with your defined value

#define SPC5_FMPLL0_NDIV_VALUE              ${conf.instance.initialization_settings.fmpll0_settings.ndiv_value.value[0]} with defined value

in waiting for new HAL Drivers with extended settings, i advice you to update this file plugin.xml in your SPC5Studio.

KEEP THE ORIGINAL ONE

or use some tips like #undef / #define in your application.

    Best regards
