I use a single-chip microcomputer to count external interrupts and give it a 1HZ pulse, but the displayed count value is sometimes 1, and sometimes 5-10. (The 12864 screen refresh time should be betwe...
Dear experts, I recently had such an idea. Encode the original RGB signal output by the 100W camera, such as h264. First, I need to determine the encoding chip, FPGA should be OK. But I am not familia...
