Discussion - Hardware / Re: BT81x to support 1366*768 LCD?
« on: January 18, 2019, 12:13:38 PM »
Hi
Thank you for the quick response. You have mentioned "The EVE series of ICs do not include a frame buffer, they dynamically clock out each computed pixel on the screen." In this case, the concept of framebuffer to store/swap a frame cannot apply. Therefore 1366*768*2bytes for a full frame can be ignored, right?
If the GRAM is not a frame buffer, suppose I have some bitmap data as an array pointed by uint16_t *fb, where this bitmap data should be copied to Eve in order to get it displayed?
Asking this question because 1366*768*2 = 2MBytes > 1MBytes CGRAM in Eve. At the beginning I was worried by this equation.
A frame frame of 30Hz may be enough good but a test is required. Is there any Youtube video or something to show your 10” HD demo at Electronica 2018 (1280x800 60Hz)?
Best Regards
John
