Other Parts Discussed in Thread: SEGGER, ,
In my project, I am interfacing lp5569 with ST MCU STM32G031K8 and using Segger Embedded studio for development. I am gettting NACK from I2C Slave LP5569. Following is startup sequence
Turn on EN/PWM
1us Delay
Turn on v1p8
2.5ms Delay
Send I2C Slave address 0x32. Below is the snapshot of the transaction. Logic analyzer shows it as ACK but MCU treats as NACK as slave is pulling the line high in below analog trace of the SDA line
Please do the needful
