LP5012EVM: LP50 EVM S/W is sending wrong I2C address to the EVM.

LP50 EVM s/w is sending wrong I2C address to the EVM. It makes not possible to communicate with EVM board.

In the datasheet, I2C address of Lp5012 is 00101XX. If I set 00 for ADDR selection, it will be 0010100 = 0x14. But In SP50 EVM S/W, I only can choose 0x28. I also checked with Oscilloscope and S/W was sending 0101000 not 0010100.

Please fix this asap! I need to evaluate IC by this Wed.

Hi Charles,

Version 1.1.1 was what I've tested. All problem that I mentioned earlier was based on this version. I reinstalled your link again but didn't resolve the issue.

Regards,

Chris

Thank you. Now I can see S/W allows to change I2C address.
