How to Remove Uploaded Code From Arduino

The ESP32-CAM AI-Thinker development lath can be programmed using Arduino IDE. This guide shows how to program and upload lawmaking to the ESP32-CAM (AI-Thinker) evolution board using Arduino IDE.

The ESP32-CAM AI-Thinker module is an ESP32 evolution board with an OV2640 camera, microSD carte support, on-lath flash lamp and several GPIOs to connect peripherals. Withal, it doesn't have a built-in developer. Yous need an FTDI programmer to connect it to your computer and upload code.

• Buy an FTDI Programmer
• Buy an ESP32-CAM AI-Thinker with OV2640 Camera

Install the ESP32 Addition

To plan the ESP32-CAM board with Arduino IDE, y'all need to have Arduino IDE installed besides every bit the ESP32 add-on. Follow the adjacent tutorial to install the ESP32 add-on, if you oasis't already:

• Installing the ESP32 Board in Arduino IDE

Plan ESP32-CAM (Upload Lawmaking with Arduino IDE)

To upload code to the ESP32-CAM (AI-Thinker) using Arduino IDE, follow the adjacent verbal steps.

Connect the ESP32-CAM board to your computer using an FTDI developer. Follow the side by side schematic diagram:

Note: the order of the FTDI pins on the diagram may not match yours. Make sure y'all check the silkscreen characterization next to each pin.

Many FTDI programmers have a jumper that allows you to select 3.3V or 5V. Make sure the jumper is in the right place to select 5V.

Important: GPIO 0 needs to be connected toGND and so that you're able to upload lawmaking.

ESP32-CAM	FTDI Developer
GND	GND
5V	VCC (5V)
U0R	TX
U0T	RX
GPIO 0	GND

To upload lawmaking to the ESP32-CAM using Arduino IDE, follow the side by side steps:

1) Go toTools>Boardand selectAI-Thinker ESP32-CAM. Yous must have the ESP32 improver installed. Otherwise, this board won't show up on the Boards card.

2) Go toTools>Portand select the COM port the ESP32-CAM is continued to.

3) For demonstration purposes, yous can upload a blank sketch to your lath:

          void setup() {   // put your setup code here, to run once: }  void loop() {   // put your main code here, to run repeatedly: }        

iv) So, click the Upload button in your Arduino IDE.

5) When y'all start to see some dots on the debugging window, press the ESP32-CAM on-board RST button.

After a few seconds, the code should exist successfully uploaded to your board.

6) When yous see the "Done uploading" message, you need to remove GPIO 0 from GND and press the RST push to run your new code.

Mutual Errors and How to Ready Them

If you don't follow the previous instructions exactly, you lot may get the post-obit errors:

Failed to connect to ESP32: Timed out waiting for packet header

This error means that the ESP32-CAM is not in flashing mode or information technology is not continued properly to the FTDI developer.

Brownout detector or Guru meditation error

When you open up your Arduino IDE Serial Monitor and the error message "Brownout detector was triggered" is constantly being printed over and over again. It ways that there'south some sort of hardware problem.

It'southward often related to 1 of the following issues:

• Poor quality USB cable;
• USB cable is too long;
• Board with some defect (bad solder joints);
• Bad computer USB port;
• Or not plenty power provided by the computer USB port.

Solution:

• Try a different shorter USB cable (with data wires);
• Use a unlike computer USB port or use a USB hub with an external power supply;
• Some readers were using 3.3V and reported that when powering the ESP32-CAM with 5V, the issue was fixed.

Board at COMX is not available – COM Port not selected

If you get the following error or similar:

          serial.serialutil.SerialException: could not open up port 'COM8': WindowsError(ii, 'The system cannot find the file specified.') Failed to execute script esptool the selected series port Failed to execute script esptool  does not exist or your lath is non connected Board at COM8 is not available        

It ways that you haven't selected the COM port in the Tools menu. In your Arduino IDE, become toTools>Portand select the COM port the ESP32 is connected to.

It might also hateful that the ESP32-CAM is not establishing a serial connection with your computer or it is not properly connected to the USB connector.
