-New version with I2C EEPROM?- Oh wait, there is an internal EEPROM.
-Uart not even neccessary. Fancy GDB-Magic can be used.
At the moment its probably an STM32L011F4P6.- Uart for configuring is needed. "Customer" should be able to configure it with adapter via USB.
So UART would be nice then. Assume its already wired correctly.
An adapter for UART to USB would be nice. So able to configure it without STLink. MCP2221 looks good.
STM32L031F6P6 has 32KB.January 2022; 2,22920€ @ 25pc. EEPROM is also integrated. Pin-kompability to be checked.
STM32L031F6P7 is 2,38520€ @ 25pc. 717 available. "Link":https://www.digikey.de/de/products/detail/stmicroelectronics/STM32F042F6P6/5268189
Pins are the same, Uart is on the same pins. Buzzer same, SWD same. has to be checked.
UART works as expected. Binary Size is still ok (Release only, Debug not possible).
STerm is way to big (4K over size). Have to look whats the issue there. Faking a 64K Version, making full debug image and check symbol sizes.
