Erik,
The routines that refresh the LCD take up a certain amount of CPU processing.
Even though the scanning is paused, the LCD is still being refreshed via the SPI lines - no?
Does your firmware version turn off all display refresh ie:display goes blank? (I haven't had a chance to install/play with it yet).
Can we remove the display routines altogether and, let's say, increase the scanning speed/etc.
Would you be able to benchmark your version with the display on while scanning and then completely disabled and scanning?
In other words, what can be gained on the device by modifying the F/W to produce a headless unit? Anything?
Regards,
Larry
