SPI basics

[flotulopex]

Thanks Darrel.

I think, I just don't get what SPI is. I assume it is a "better" or "easier" way to make things communicate.

However, I don't understand what and how I do have to implement things.

Again, my goal is to simply send the universal "Hello World!" on a SPI display.

I'm using a 16F690 that has an SSP module; fine. I see, there are two registers SSPSTAT and SSPCON I'll have to define.

Well then, let's enable the SSP module: SSPCON.5=1. Great!

And now, what do I need to do to make my LCD display the famous phrase?

I'm completely lost

Don't even try using the MSSP module until it's working with SHIFTOUT.

What mfg/model is your SPI LCD?

IF this thread gets on going by teaching something really useful and the teachings are easy to understand, I will also keep staying on it and try to learn as it goes. I am also on the same track as flotulopex.

I would very much appreciate useful inputs from people who are eager to teach this subject.

I'll second that.

See Hardware SPI.

Warning, other compiler.

Thanks Darrel, I understand only now what you meant in a previous post
