Install ESP-IDF to the PC you will be using to flash the firmware to the ESP. Getting Started with ESP32

Launch ESP-IDF command promot or powershell linked from desktop or startmenu.

Change directory to ESP32 sub-directory, inside ESPStream folder, then execute:

idf.py build flash monitor

You should get output similar to this if it succeeded.

If you are using a different ESP board you might have to change the SDKCONFIG file via:

idf.py menuconfig

Please check your board and set appropriate resources accordingly

For information on setup for build enviorment please refer to:

Main project with test case ESPStream_test.c, ESPStreams files are ESPStream.c and ESPStream.h. there is also a bash script file for debugging that I added to help with this process happly named debug_ESPStream_test.sh if you feel inclined to do so.

There are a few hardcoded path's in the makefile that should be change to reflect your NDK file path to point to needed include files and libraries.

need to fix this

• Resolution control for camera's
• Image capture input to write current image to storage
• encryption for image trasmission.
• multi-platform

This project in it's current state is a Proof of Concept for using a SPI interface ArduCam to work with ESP32 proto-type boards.

11/24/2022:

Switched from Arduino build to ESP-IDF build.

Multi-threading is being used for camera function and network function.

Added C wrapper functions to arducam_esp component.

Fixed frequency issue with interface_spi.c set manually to 6Mhz.

Now getting upwards of 15 FPS.
