figure-1 I2C waveform with STM32L433rc-p Nucleo board.
When I try to use STM32L433RC-P Nucleo's I2C for communicating with AT24C01 I2C EEPROM, two strange waveform occurred. This strange waveform is not occurred from another model STM32 MCU.(example. STM32G0xx Nucleo board. See below figure.2.)
1. It makes strange low level spike.
2. It makes strange and very narrow I2C waveform compared to other STM32 MCU devices.
I used HAL function "HAL_I2C_Mem_Read(&hi2c1, 0xA0, 0x00, 1, &dat, 1, 1000);" for I2C commucating with AT24C01 device.
I didn't experienced any I2C communation error with that strange waveform, but I want to confirmed this strange waveform don't affected I2C norminal operation.
Is these strange waveforms normal case?
