LDC1000 read data SPI issue

Marian Golli

Welcome
I took my plate with ATMEGA168PA and LDC1000.
LDC1000 system configured and running.
But I have a problem with the receipt of data from LDC1000.
System after sending to it only returns 0x21 0x255, 0x0, 0x0.
I attach a screenshot of course the CFI.

Hi Marian,

The chip select (ENABLE) pin should not go high in the middle of your packet; it should stay low from the first byte (0x21) until the end where all bytes are read.

What is happening is the LDC1000 thinks there are two packets/transactions instead of one.

Thanks,
