Hi Dialog,
There is only 6 color bit output lines on DA14695. Can DA14695 Parallel LCD Interfaces support RGB565/RGB666/RGB888? Such as RGB666 , if DA14695 can support it , is that means it will cost 3 time LCD clock time to transmit one pixel data?
Device:
Hi guxiang,
In the Parallel LCD Interface, the controller will take out all the color bits for each pixel in only 1 clock cycle.
For instance, in case of the RGB88 : 24 parallel bits (color information : of which only 6 are available in the DA1469x device family) will take out in 1 clock cycle.
The color format is not depended on the interface (serial, parallel, etc. ) will be used.
It’s possible to have various output color formats such as RGB565/RGB666/RGB888, but in all cases the DA1469x will take only the 2 MSBs from each color as an output. So, in the parallel interface, 6 bits will take out in 1 clock cycle.
