The Xprotolab has a really nice high speed frame rate for refreshing the waveform - faster than my Tektronix scope!

The Xminilab refresh rate seems much slower.  When I look at the SPI signals for the display, the Xminilab takes about 2 ms to write the screen, but the frame rate is only about 4 fps.  Is there a way to make it update the display more often?

 

Also, the link on the site for the Xminlab schematic is incorrect - it points to the Xprotolab schematic instead.

EDIT: It's the Xminilab source code link that is incorrect, not the schematic.

OK, I figured out how to guess the correct URL for the source, but the source appears to be for an older version, based on how the code assumes a parallel OLED interface and the schematic says SPI. Is the source available for the currently shipping version?

I'll check the refresh rate. I'll upload a demo version of the source code this week.

The refresh speed is the same as the Xprotolab, perhaps you were checking with a slow sampling rate. The real fast display refresh rates occur when the time base is faster than 512uS/div.
I have uploaded the xminilab demo source code.
