connect butterfly to 5V circuit.

connect butterfly to 5V circuit.

2007-01-15 by gpolder

I like to interface a butterfly to a 5 volt logic circuit (actually an
analog devices dds). What is the best approach?

1- run the butterfly on 3 volt and just connect the output to the 5
volt dds inputs?

2- use level converters between the two?

3- run the butterfly on 5 volt?


thanks,
Gerrit.

Running the Butterfly at 5 volts and connecting to 5 volt logic circuits has 
worked fine for me.

Is your external memory chip still working?
It annoyed me it's max rating is about 3.6V, so I never dared to power it at 
5V, but I sure wish I could.
Maybe you don't use it, so you don't know it's gone?

Cat,

Ah, good point.  I don't use it so I don't know.  Mine could be toast now... 
If you have a sample program that you would like me to try I would be 
willing to do so and let you know if works or not.

I don't have something that wouldn't need modifying, but I think the 
original application stores the name you input (for badge mode) in that 
external chip.

You can either get the real original from Atmel, or a GCC version from... 
someplace on the web.
