LP5024EVM: LP5024EVM

Part Number: LP5024EVM
Other Parts Discussed in Thread: LP5024

Hi Team,

I have given the VCC, VLED, and VMCU 5V and remove one of the pads of R1 and R2 from and connect others side pad with I2C SDA and SCL line with QCS403 processor who has 1.8V SCL and SDA line and it has pullup also to that pin.

and I have given 1.8 V pullup to enable pin.

but I am not able to detect the i2c device address.

Kindly help me

  • Hi, guy,

    Would please provide more information about your problem? such as attaching the wiring picture of the LP5024 EVM or some waveforms. and what did unable to detect the I2C address mean?

    Before that, i hope you can measure whether the supply of VCC check point is corrcet? And when you send the address of device, can you receive the ackonwledge  from the SDA?

    Best Regards
