Arduino for STM32

Thanks very much!

Hello.

I need to be educated on this a bit.

I just bought a bunch of WeAct stm32F103CB BluePills whose internal LED is connected to pin PB2. I have an STLink and the STM32CubeProgrammer software installed. I couldn't find a hid_generic_pb2.bin file to flash so I just used the hid_generic_pc13.bin ...

are you using the 'official' STM core?
that core is bundled with its own 'eeprom' lib

for 'blue pills' there are quite a lot of 'gotchas' and pit falls
recently quite some (blue) pills appear with stm32f103 c6 32k flash ...

You're overwriting data in EEPROM. And it couldn't work before.
size of int is 32b not 16b like on ATMega 8b MCUs.
You need to put them every 4 bytes or use 16b variables.

As to life cycle - no, it's not. Virtual EEPROM is put in flash memory and it's life is about 1k erase cycles. But virtual ...

First of all, thanks for being here. This is my first post and I apologize if you find it too long.

What am I missing or Did something recently change with the EEPROM.h library? I have a program that I initially developed on an Arduino Nano, but have successfully adapted the code for use on a ...
