I am interfacing a MSP432 microcontroller with a SHT21 sensor. The I2C bus contains only these two devices and has 2k2 pull-ups.
The problem is that the sensor continually generates impulses on SDA line and because of this I cannot communicate correctly with the sensor. I've tried changing the sensor with another one, but it behaves the same.
This is how the pulses look like:
The datasheet and Internet forums do not say anything about this behavior. It is weird that both sensors behaved the same. When I remove the sensor, the SDA line is OK.
The sensor is not PWM type because the frequency is much higher than that described in the datasheet.
Has anybody encountered this? Could it be a hardware-related problem?
