Hi.

I have GUI app with two framebuffers in external SDRAM. Display size 640x480. One buffer show on display and other must be updated in vertical blanking period. So what line value (0 or 479 or 480) must be programmed to LIPCR register to identify start of vertical blanking?

Thanks.

This function writes to a register LIPCR. Now I’ll try to find info from the reference manual, but if someone knows about it, can he tell us? Thanks.
