Interfacing Microcontrollers with the real world

[lindworm]

Hi all,

I'd love to see more tutorials, especially on how to actually do a good job in designing standard I/O circuitry for microcontrollers and also how those parts work.

For example:
- ADCs: which kinds exist (...delta sigma adcs anyone?), how they work, and how what you should do to make a proper design (for example I had 2 ADCs in parallel for educational purposes and had to use impedance converters as their input resistance drops while sampling) probably enough for 2 or more blogs alone
- the same with DACs
- how to protect your circuit from the rest of the world and vice versa aka how and why do you galvanically isolate interfaces
- how to use (for example) UART
- perhaps a short one on PWM
- maybe something about interfacing relays (this is pretty informative: http://jumperone.com/2011/10/using-relays/)


So what do you think? I'd be amazed if some of this stuff would find it's way into the blog!

Kind regards

mhh, isn't anybody else interested in those topics?

Hi there

you may take a look at this article: http://www.bipom.com/applications/micro_interfacing.pdf , as well as this universal interface http://www.ichaus.biz/product/iC-JX.

I hope this is useful.

Hi Rudolfo,

thanks for your reply, the PDF is a good overview and certainly helpful for beginners.
I consider myself quiet well informed about those topics, but everybody can certainly still learn a lot detail they didn't think of in the first place, especially how some of those components work in detail.

That's why I suggested those topics as everyone who wants to get into micros has to cope with those things and more experienced users can probably also learn additional detail or tricks.

Best regards
