eh, Arduino the library may be too slow, but underlying chip, atmega328, is definitely not. It runs at 16MHz, and most instructions are 1 cycle long (things like jumps are 2). > Strobe pulse is 5us wide (200Khz) so for reliable sniffing I should read I/O ports at 1Mhz. The best I could do was reading necessary 13 channels at 80Khz. You don't need general protocol decoder, you need to wait for strobe and capture a byte. And you don't need all 13 lines - most firmwares use same byte sequence for each frame, so you can detect frame start and just count the bytes. A main loop may do: - Wait for frame start - Capture a frame worth of data - this is 8192 pixels, which is 1024 bytes, which is a half of total RAM - Slowly send data over serial.. You will miss a couple of video frames, but this is OK, the picture is mostly static. And you don't even need assembly - the strobe is 80 cycles long, and it looks data comes every 100uS or so - that's 1500+ cycles! Super slow, even inefficient C program can handle it.
