I am trying to connect eeprom to the blackpill but it is not working.
The way I am testing this by changing some settings values and disconnect and reconnect the board again and read the value but it always revert to its default value.

I have connected 24lc32a and 24lc256 on a breadboard with the black bill, I have set A0,A1,A2 all to 0 and I have checked the address using i2c scanner with Arduino and confirmed the address was 0x50 also I have changed the address in both
eeprom_24LC16B.c
eeprom_24AAxxx.c

I have set EEPROM_ENABLE to 1 and also to 2 but nothing happen.
I have enabled I2c by adding those lines in my board.
#define I2C_ENABLE 1
#define I2C_PORT 1 // PB8 / PB9

I have changed input pin assignment for user-control controls (cycle start, reset, feed hold) input pins since it has some conflicts with I2C port.

How exactly should I know that the firmware is aware of the eeprom?
