The following configuration is being used:
Bitsy
Optrex DMF 50961NF-SFW monochrome display
image build 4.11, ROM 1.75 (in other words, a .NET build for the Bitsy)
When the new files are installed on the device, the screen display not only flickers but is ‘damaged’. The bottom half of the screen is ‘missing’.
Regarding the flicker, since the color and monochrome LCCR3 entries in the HWT are dissimilar (see below), would you be able to suggest a value to use for the monochrome entry in order to eliminate the flicker?
When I load the CE 3.0 image and ROM onto the above system, everything is fine.
