After I have looked on CHDK and PTP for a fews modules.
In this forum. Someone have pointed-out that the minimun interval is around 15 sec;
So Is it possible to build real-time WebCam by hacking and do something with hardware???
In my hypothesis.
If we call
state_shooting_progress = SHOOTING_PROGRESS_PROCESSING;
and then we get an address of raw data using hook_raw_image_addr();
now we use their LEDs to transfer data!!!
define LED_BLUE 0xc0220084
define LED_1 0xc0220088
define LED_2 0xc022008c
define LED_3 0xc0220090
define LED_4 0xc0220094
Then use assembly to blink them in 4 bits nibble or any possible protocol.
on the host side (PC). Maybe mcu or some sort of MCU will tap the signal and send it to PC using custom or generic protocal.
Is it possible?
If it is possible, How much possible bandwidth in data transfering (Theoretical with assembly language)
