Cam Client

 

Through this week I tried to figure out how to program an ESP32 CAM with an FTDI, to connect to a wifi server (setup using another ESP32 connected to an LCD) and send images across to be displayed on an LCD screen.

 

ESP32 CAM

ESP32-FTDI connection

I found a pinout connection diagram to connect the FTDI to the CAM. On thing to note is that once the CAM has been programmed, the GND P10 connection had to be disconnected for the CAM to connect start sending data

 

Code

This is the code I used - a slight modification of the ESP32 CAM example available on the Arduino IDE through the ESP32 library

 

The serial monitor shows the cam connected to the ESP32 LCD server - Grabbing the frame from the camera module and sending it to the server as binary data
