I need help/guidance on how to interface a camera module like an ov2640 to ESP32-S3.is 10 pin enough? because on the esp32-cam it looks like the camera use around 16pin (I'm short of pins). btw i know very little close to nothing on how to connect an camera module like ov2640 to ESP32-S3 and the software/programming. but I'm here to learn more. it's a little hard to find information about this (i wish i had a mentor/teacher).

i don't think it's a duplicate. the "NTSC/PAL Camera for ESP32", is asking is it possible to use NTSC/PAL camera with esp32-s3. while on this one, i just asked how to interface a camera module with CSI/CPI like an ov2640 to esp32-s3. basically i asked how to replicate ESP32-CAM in my design.

You definitely need more than 10 pins, as far as I can tell:

  • 8 parallel data lanes, which you will have to connect to pounds of the same gpio bank if you want anything like working dma transfers
  • 1 clock pin, generated by the Microcontroller
  • 2 pins for the I2C control interface

And if I remember correctly, there's a few other reset and synchronization pins.

I think you're underestimating the difficulty of this. Maybe start looking up the data sheet of your camera module (it can easily if not officially be found using a search engine of your choice), and go through the descriptions of the pins. Take notes on the function of each pin! If you have a question on the function of a pin, which you can't solve by doing reasonable own research, feel welcome to ask here.

  • \$\begingroup\$ Thank you for replying to my question. i have 10 pin that's empty, 2 pin is already used for i2c, so i think i can put my camera i2c line to that pin (on the same bus). and i still have 4 jtag pin that i can use, but as far as i know i need to burn some "e-fuse" which honestly i don't understand on what is e-fuse and how to "burn it". also, do you maybe know generally the pins on ov2640 camera module that already have and flexible ftp connector? \$\endgroup\$ Commented Feb 25, 2024 at 7:05
