TLA2024: I2C communication is failed
Part Number: TLA2024
I used msp430f2001 to control ATL2021, but found that IIC could not communicate. I observed the waveform through an oscilloscope and determined that the device returned a high level.However, there is no problem with my device address and waveform timing sequence. Could you help me analyze the cause of the problem?
I2C configuration is below.Sleve Addr : 48h (ADDR Pin : GND)
Vdd : 4.0V I2C BUS Pull-up Resistor : 2.4K Ohm
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

I followed your advice and extended the time of the ninth SCL high, however, the slave machine still did not ACK.
