Hi, I'm trying to setup a stm32g070kb (32pin) MCU as I2C slave by using CubeIDE.I would like to create a code which will work same as I2C Eeprom, but when I ask the stm32 (with another MCU) to return me a register or registers value, the returned reg...

The first picture was taken with 16MHz here is a new picture with 64MHz.The "gap" is much shorter but the behavior is still the same.I added also another picture with clock stretching enabled, the data line stayed high instead of low.The eeprom reque...

thanks, when I enable clock stretching , I can write data succesfully to the stm32 but it answers incorrectly, when I checked it with the oscilloscope looked like the dataline polarity changed. ???the stm is running on 64mhz , are you suggesting dela...

I'm sure it's not my misscounting because (as I described it) I ask the STM32 in the same way as I ask the EEprom.I use an arduino as a master I2C to ask two slaves, STM32 with address 0x48 and the EEprom with 0x50 address.I use this library #include...

Thanks AScha.3 for the quick respond, I have tried that and with disabled clock streching the master can't even detect the stm32 slaves address .
