Possible to have two LCDs displaying same content? #322

Closed digitalman2112 closed 8 years ago

digitalman2112 commented 9 years ago

Is it possible to have two LCDs displaying the same content? I have an application that requires a small lcd on either side of a partition showing the same video, and didnt know if this was possible either by simply branching the SPI signals or through driver configuration.

I don't see any problem in connecting 2 similar displays to the same SPI Chip Select line (don't connect MISO). Except for fb_ili9320, no driver tries to read from the controller, and even that doesn't affect functionality.
