SPI Slave

[Pkats.1]

In my Application, ill use 2 uC stm32h743.

Between both, my plan is to apply a SPI interface, when one of them will be the Master and the second will be the Slave.

My first question is, does the uC can work as Slave? does clk pin can work as input at the slave side?

Second, should i connect Mosi pin of Master uC to Miso pin of Slave uC ?

Yes, if you set it so.

> clk pin can work as input at the slave side?

Yes. Usually denoted as SCK in SPI.

> should i connect Mosi pin of Master uC to Miso pin of Slave uC ?

No. Connect MOSI to MOSI.

Read the SPI chapter in RM.
