I have made a pcb , taking ltc6804-2 demo board as reference. Below is part of SPI communication. DIO2 is MOSI and DIO7 is MISO. The data on MISO does not have correct pec. Is there any way I can check if ltc6804-2 IC is not faulty?
Found the problem , it was pull up resistor connected to MISO line. I was using very high pull up resistor. Changing it to 5k solved the problem.
