Hi, friends, we know the RPI has a video memory, and the HDMI or composite video, out put to screen, the content of this memory area.
My question are, can I write a pixel directly into of this memory?
What is the physical address of this memory?
please remember I am not using any framebuffer driver, my idea are put a file.raw date directly to the video memory.
I will be very grateful for some help...
