No problem, things get a little heated sometimes, and then we have to raise a flag. Discuss all you like, express opinions, no problem, just keep it professional. (Unless it's about how PICs suck.. !) On Wed, Aug 12, 2009 at 6:29 PM, Graham Davies wrote: > --- In AVR-Chat@yahoogr

Clamping to the Vcc rail in this app might not be a good idea. If the current draw of the entire cct is low, and the Ain voltage goes too high, it'll just pull the rail voltage up too. So then you need a Zener on the Vcc rail. So just use one on the a/d in, instead. Regards Rolan

I can't recall the circuit for the Butterfly, but if I was you I would put a 5.1V zener diode across the input to the AVR ADC input just in case your input goes above 30V or you resistor fails for some unknown reason. This was you will protect the AVR from damage. I find this goo

Graham thanks for the insult about my brain not being in gear. Is that the respect you give to all the people whose opinion you don't agree with, insult them. Grow up; quit calling people names and insulting them. And I do stand by what I said, "I don't trust them", companies tha

The Butterfly will read 0 to 5v. My question is can I get to to read 0 to 30v simply or would take a lot of hardware?

You already have a Butterfly and Butterfly Carrier. Joe Pardue of Smiley Micros http://www.smileymicros.com/ is big on the Butterfly as a AVR learning platform. He has written a book, "C Programming for Microcontrollers" selling for $45, http://www.smileymicros.com/index.php?modu

A Butterfly will get you quite a ways. It IS inexpensive. It will allow you to develop some skill with C. With a built-in bootloader, it is relatively easy to use. It IS short on a diversity of I/O. In addition to the LCD, there is a beeper, I think. It will let you learn a LOT a

Depending upon your source, the internal A/D capacitors retain a certain amount of the voltages you are sampling. Try sampling a grounded signal (or the internal ground) before sampling your POT. Yingdan wrote: > > > Hello, > > I am using VREF+ and AVss for a potentiometer. Below
