I want to learn about this pattern where you write to a video memory area and then that gets processed separately and displayed on a monitor or VGA or what not. Maybe even something like what the #GameBoy does where tile maps and blit is done separately based on what you wrote to the video memory region. Does anyone know of any resources to implement something like that with #PiPico or #Arduino?
Two microcontrollers, where one writes directly into the other's memory, and the other does whatever processing and outputs video? I don't know if this is necessarily something practical I need to do, but I'd like to learn more about it. I've been reading about using DMA to communicate via SPI or UART and it reminded me of this.
