Hi,
I want to interface my 5v controller with board LP5024EVM. I give external supply to LP5024EVM. Is I2C communication work on 5v?

Hi,
First I connect LP5024EVM with USB2ANY and its work fine. LED pattern is generate.
After that i connect it with my 5v micro-controller. connect VMCU to VCC(+5v). but it can not get response from board. Both address pins are grounded so i use address(0x28).
5v controller communication not work so i use 3.3v controller i2c communication . same way I2C communication is not work with 3.3v controller.
At last I again reconnect LP5024EVM with USB2ANY. now it doesn't work with is condition also.
what is the problem?
Thanks,

Hi kenneth,
Now finally I am trying to communicate my LP5024EVM with MSP430FR5994 3.3v controller. But my code stuck at i2c driver library.
It is stuck at line
"// WAIT FOR THE FIRST TXBUF EMPTY INTERRUPT BEFORE LOADING TARGET REGISTER
while(!(UCB2IFG & UCTXIFG));"
in readI2C function.
My i2c work properly with other i2c sensor.
I want to know that what is the problem?
Thanks,
Dinkar
Hi kenneth,
My original setup is not working.
Also i check with address 0x29 , 0x2A , 0x2B but i2c is not responding.

Hi kenneth,
We already have 2 board of LP5024EVM. But both have same problem.
We also change IC in one board but still have same problem.
