Other Parts Discussed in Thread: MSP430F2001,
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
