Integrating the camera driver into MicroPython.

Programming the esp32-cam processor

The esp32-cam does not come with a serial USB interface as many other ESP32 processor boards do. This makes programming the device quite a bit more tricky.

Having a look at the pin-out we see that GPIO 1 and 3 are connected to UoTXD and U0RXD respectively.

These will be the programming pins connected to USB to serial converter.

Here are the connections:

ESP32-cam
Power 5V left side of esp32-cam	external power supply 5V
GND left side of esp32-cam	external power supply GND
GND top right of esp32-cam	USB to serial GND
U0TXD	USB to serial RX
U0RXD	USB to serial TX
GPIO0	connect to GND when flashing
GND

In order to understand how to program the device the circuit diagram will be very helpful.
