That's correct! To see the icons, you'll need to set a break point toward
the bottom of glcd_test.asm. Look just after the calls to
LCD_RefreshDisplay. The "wedge" shape is actually code to test the line
drawing algorithm. I repeatedly draw a line starting from 0,0 down to x,32
and let x run from 0 to 100. (Remember that are several things being
tested here: one is the Assembly code for doing the graphical stuff. The
other is the C++ code that implements the model of the graphical LCD. And
finally, there is the test of making sure everythings connect correctly.)

Hmm. This is undoubtedly an artifact of some experimentation I'm doing
with clocking the processors externally. I'm not sure if you've followed
some of the recent gpsim threads, but I'm working on a new clocking
mechanism. The code thus far passes all regression tests, so I left the
experimental code turned on. If it's important to turn it off, then you
can comment out the line '#define CLOCK_EXPERIMENTS' in src/clock_phase.h.
BTW you can use hot keys to initiate a run.
With the focus on the source browser, pressing 'r' will initiate run.
Similary, 's' will single step. The numbers 1 through 9 will step 1 to 9
times. Also, <ESC> will halt a running simulation.

I'm not sure what you mean by no success. I think it's working now, it's
just a matter of interpreting the results.
