Hello there!
I have an evaluation kit LDC1000EVM, with the portion of the EVM (just LDC chip and PCB coil) I have been trying to connect it directly via SPI protocol with a different MCU and I have not been successful. I used a fuction generator like an external source clock at 6 MHz. I hold a pic where it shows the waves forms of the interface. I don't know what is wrong. I don't have achieved the communication when I send 0x21 and 0x22 to obtain the proximity data. I set the POWER MODE to 0 before setting other registers and the parameters of the pcb coil are equal like the software GUI shows it, the VIO voltage and the VDD are 5 V.
I will be gratefull for any help you can provide.
Sergio D.
