Hey guys,
I'm working with an ATmega32 on an STK500, and also on a breadboard which
is the eventual target. I've been struggling to get UART to work, and now
that I did succeed, I can't get a baud of more than 9600. Now, with the
STK500 and the software clock, I get get 38400 - 115200, but with the
external oscillator plugged into the STK500 board I simply cannot achieve
more than 9600.
Anything more than 9600 results in garbage. Yes, I'm setting my terminal
emulator accordingly.
I *am* using an external oscillator, running at 8.0 Mhz.
I did set the fuse bits accordingly, does anyone have any ideas? I moved
the OSCEL jumper and left the XTAL1 jumper mounted.
I know the external oscillator is working because when I put it on the
breadboard the chip works, but when I remove it from the breadboard the
chip freezes up.
Any ideas? Anyone else ever struggled to achieve more than 9600 baud?
Thanks,
