I'm in the FPGA chip design, brother gave it to a task, also let me do the test report, now have the spi module project and driver code, where should I start to see, how to just calculate understand thoroughly the spi communication protocol, strives for the show just a little big, best detail

CodePudding user response:

To understand the working principle of SPI timing problems (work), SPI can use a hardware resource, some can be simulated,

CodePudding user response:

Offline can draw sequence, the basic can understand SPI agreement,

CodePudding user response:

SPI agreement still need you so difficult?

Three basic SPI pins: CLK is clock, MOSI the Lord from the MISO master into from the
Host machine from the same number of pins connected

This host from the machine to connect into two shift register group, under the clock driver, at the same time for data exchange
If you still don't understand, just to see how shift register work

Thank you bosses, help the younger brother thanked here
