Hi,
I want to communicate via SPI with the ICM-42688 and came across a quiet simple problem:
In the data sheet chapter 9.6 SPI INTERFACE it says that all pins are described with respect to the master. As the ICM-42688 always operates as a slave, I thought SDI must be MISO and SDO must be MOSI. On the other hand Figure 6 indicates, that SDO is MISO and SDI is MOSI.
Can anybody clarify, whether there is a mistake in the data sheet or am I misunderstanding something?
Thanks a lot and best regards,
Niklas
SDO = MISO
SDO is Slave Data Out which is MISO Master In Slave Out.
SDI = MOSI
SDI is Slave Data In which is MOSI Master Out Slave In.
Thank you for your help!
