For me it *is* their only product :-)

Would that justify the higher price compared to the TI equivalent?

What do you call that configuration, "do nothing" ?:-)

Yes, but for a scope inverting is not good ;-)

Indeed.

Pfft, just

comf data,1

Or if you don't have time to explicitly negate the operand, rearrange your display so zero is at the bottom of the screen, increasing upwards. Then it will be mathematically correct, too ;-)

Yea, if you had read my report on doing the display driver for the LCD19-Samsung, I mentioned that I had to write a lot of code to make it work from right ot left to bottom up :-) It is not so simple, but there exists a simple solution: Stand on your head, and you can flip right left too with a mirror. Or use an old analog video camera and reverse the scan. Or reverse the scan on the CRT... If all that fails move to Australia.

An inversion at the circuit level is not necessarily an inversion at=20 the system level; especially for a software driven system.
