G'day all,
Just trying Gpsim for the first time in a while.
Compiled and installed fine on a Debian Woody system,
simply had to apt-get install libpopt-dev.
Is there a known bug with the uart emulation regarding
fast baud rates?
With a Pic 16f877
I'm emulating a crystal speed of 12.228Mhz with
BRGH=1 and SPBRG=2. This should give me about 255kBaud
Gpsim reports about 188uS for a byte, when it should be
about 43uS.
SPBRG=1 give me about 118uS which is way high..
I have a breakpoint set on the tx Isr and stopwatch between
breakpoints.
Is there anyway to watch the internal state of the uart,
or breakpoint on it's output pin changing?
I tried setting a break on portc writes, and port c values
but no joy. I tried looping the tx pin to a portd pin and
setting a breakpoint on that also. No go..
Great work BTW. The combo of gpasm/gpsim/picp has just about
obsoleted mplab for me. Just need to add a 16f876 to gpsim :p)
I may look at that if I can find some time.
