About Parallel Communication

[pass3master]

We want to do parallel communication. How can we do parallel communication with the following microcontroller?
Is it possible to perform parallel communication by using I2C function?

What do you mean by parallel communication?

How should a serial bus such as I2C communicate in parallel?

Just explain : what is "parallel communication" in your world, but if you obviously want to use a serial port (I2C) ?

[pass3master]

We call communication standards such as PCI and SCSI parallel communication. Is it possible to connect to them with the target mcu?
Would GPIO be able to achieve this?

There are many different implementations of PCI and SCSI. As a rule, however, we are talking about current high-speed variants that you cannot handle with bit banging via the GPIOs. It may be possible to discuss your task in more detail if you provide more precise information about what exactly you want to do.

Basically yes , at low speed some "parallel communication" could be done with just using GPIOs .

But nothing really useful, or for hi-speed PCI and SCSI bus .

Just look at the general description of a cpu (or soc) , especially whats written under "communication interfaces " , then you can see, what is there : (on H563 , as example here)

So here the " One 16-bit parallel slave synchronous- interface " could be useful for your idea.
