I am not able to use external eeprom - no room on PCB and much space in STM flash.

Hi.
Thank You for information.
Sketch it is quit long application initially written on AVR arduino.
It is automatic Telegraphy keyer with many options.
Configuration and texts for automatic transmission is stored in eeprom.
Since STM based board are supported by Arduino application could be compiled ...

Thank You for advise.
I doidn't find answer for my qustins on links provided.

I was trying to play with eeprom configuratios, increasing pagesize , changing pages base addresses, but ...
