How is video output generated and synchronized at 320x200 resolution from individual single-pixel MCUs?
Each MCU in bitluni’s build is assigned to generate one pixel of the 320x200 (QVGA) frame, so the full image is produced in parallel by 8,192 CH570 RISC-V microcontrollers. The cluster’s per-pixel outputs are combined to form the frame at QVGA resolution and driven as the video signal; timing and synchronization are achieved by coordinating the MCUs so they output their pixel values in the correct order for the 320x200 scanout.
