save image to SD? #13

Open zoomx opened 5 years ago

zoomx commented 5 years ago

How about to save a single image on a SD? I believe that Teensy 3.5 or 3.6 can do that (once ported as I see on Issue #12), but I wander if it is possible with an STM32.

I am not sure, maybe it can be done. stm32 (blue pill board) has 20kB of ram. It is not enough to hold a frame but it might be enough to to buffer the image while reading from camera->writing to SD card. The main problem is that writing to SD card is slow
