Reverse Text on MD-HMI?

[Joel Moore]

Is there by any chance a control code to reverse the "color" of the text on the MD-HMI (i.e. light text, dark background)?

Alternatively, do you have a link to a spec sheet for the display on your MD-HMI?

I am not aware of such a mode in the LCD display of MD-HMI or LCD420.

The MD-HMI display is the same as the LCD420 so you can download the spec sheet from:

or more directly: http://www.optrex.com/pdfs/Dmcman_full.pdf

Thanks.  That Optrex doc looks familiar.  I must have looked into this before and managed to forget.

But yeah, I agree.  This doesn't look possible (or at least too difficult to implement).
