Saving images on the Raspberry Pi 4B from the OV5642 camera

[emmanuel-nwogu]

How do I save images from an OV5642 cam connected to a Pi 4B? The most recent support message concerning this points to https://github.com/ArduCAM/RaspberryPi/tree/master/SPI_Camera but this mini-library streams images to an app and does not seem to save them onto the Pi itself. I would appreciate any pointers on how to do this.

I was able to get this fix to work for me. I forked @dhylands's version here and changed the following for my version:

• Uncomment the BCM2835_PERI_BASE for raspberry pi 4 and comment the others in bcm283x_board_driver.h.
• Set the CAM_CS1 in Arducam.h to the correct GPIO I was using

Inspired by ArducamDemo.c, I then wrote a Save_To_Pi.c that continuously wrote images to a text file. Here it is. It's very bare-bones but it's simple enough to let you (and future me) know how to save images. After writing this c code, I changed the makefile to build an executable for it instead. Here is the new makefile.
