Hi!
I have a Microcontroller (Fujitsu MB90F347) running with 5.0V supply
voltage and a bluetooth module (Zeevo 3001Z) with 3.3V. Now I want to
connect them over UART.
Usually I would connect them directly. But this might not be possible
because of the different voltage levels.
Is there a simple solution how to do that? Perhaps I could convert the
signal twice using a MAX232 or similar. But as I wrote in a previous
thread, this somehow doesn't work. But I don't know why not. Any idea?
This brings me into serious trouble since I am not able to do further
work on this whole stuff and I have to match some deadlines. I am
really helpless because I just don't understand why this whole thing
doesn't work...
If anyone has an idea how to make communication possible, please help
me!
Thanks in advance,
Susanne Fischer
