Spi connections

[Rajinder]

Hi all,
I am connecting a 4 wire spi to 4 wire spi.
Master is a micro, slave is a temp sensor.
Do I connect as follows
SCLK to SCK
SS to CS
MOSI to MOSI
MISO to MISO
The micro is the master.
Thanks in advance

@Rajinder : do you do any research yourself before coming to this forum?
It's not that we don't want to help, but a bit of cooperation on your side is appreciated.

Hi, I did some research and it said what I have mentioned on one website, but on another it was different, hence I wanted some clarification. That's all. Sorry.

I have limited SPI experience but it is my understanding the MISO (output) will connect to MOSI (input) for communications.

If you had said so and included the links to these sites it would have been clear to us that you had done some research which left you with doubts.

No.
MOSI is MasterOutSlaveIn and is named so on both master and slave.
Same for MISO (MasterInSlaveOut).

Hello,

Digikey has also an info page on SPI:

Thank you @bertus. That clarifies lots. @Harald a while back I used a uC to communicate with a chip using SPI. I connected the chip's MOSI (input) to the uC's SDO (output). That's the reason I thought the outputs connected to inputs.
