esp32 cam tft display free sample

At first it was not successful, since most examples useTJpg_Decoderand it use a lot of memory, causing the ESP32-CAM crash then reboot. Then I found out that there"s an function from the ESP32 library to convert JPEG into RGB565 (which is the format used by the Adafruit driver). I can even scale the image to 1/2 side size (= 1/4) so it fit the ST7735S 160x128 or 128x128 displays nicely. Everything works and problem solved.

You can find some more details about wiring, the training data (Kaggle Cats and Dogs Dataset) and the model (MobileNetV1 96x96 0.25 with transfer learning) on my repo. There"s also a copy of my model library and a boilerplate version (without using button and TFT).

The train accuracy is 89.8% and test accuracy is 86.97% on Edge Impulse. Captured image is 240x240 (resized to 120x120 on TFT and 96x96 for the model). Model inference (predict) time on ESP32-CAM is 2607 ms (2.6 secs). It"s not fast, but the setup is so cheap I think this can actually be useful as real world applications...?

I have updated the arduino IDE to 1.8.9 and ESP32 boards as per instructions, but cant find the problem. If you have any ideas I really appriecate it.

Hi Dan, yes I took Sara’s advice and selected the correct camera module in the code but commenting out the ones that don’t apply. I did also find reducing the upload speed made things more stable. I think my programmer is not the best.

Hi Dan, did you found the solution. I also purchase two units with different brand with same issue. (the first one have successed before but when retry to reupload the issue came).

Any way you know of to see the video stream or stills via a TFT display on another ESP through web browser or otherwise? I’ve used ESPNow between ESP12’s or 32’s for display of thermal cam images but they’re much smaller. Avoids need for phone or laptop tied up….

Alternatively, if you have the latest updated ESP32 add-on, you should have the code in your examples. Go to File > Examples > ESP32 > Camera and open the CameraWebServer example.

I was looking for something like this for my recent project, Thanks! Great tutorial! But I think ESP32-CAM is “unofficial” combination of ESP32 with a camera. I think Espressif themselves released a dedicated “official” ESP32+camera board called ESP-EYE with their own “official” software library called ESP-WHO.

We haven’t fully tested the ESP-EYE yet. We’ve played with the example firmware that they provide and we made a blog post about it that you can read here: https://makeradvisor.com/esp-eye-new-esp32-based-board/

Try to check the cable, connections, power source … etc. If you can, try to measure the voltage that goes directly to the pins on the ESP32CAM board. It should be the closest to 5 Volt.

Thanks, it will be of great help, recently I was able to integrate my esp32 cam into an MQTT client library, every face detected a publisher is sent to the broker

I’ve selected AI Thinker in the code and reduced the upload to 115200. Anyone have some insights? I have a M5Stack Camera which works pretty well with the code but these two are dead.

There is a small red led (GPIO33 inverted) . The main led is controlled by GPIO4. In the example CamWebServer program there is AFAIK no possibility in the webserver to switch the main LED.

That occurs selecting AI Thinker. The other two options give me the 0x20001 error. I bought the esp camera from DIYMORE.CC. The description in their ad prints AI Thinker on the chip, but my actual device does not have AI Thinker printed. It just has DM-ESP32-S.

Then the web service did not appear in google chrome browser. Error message was something about too much header lines or so. In MS Edge it was ok. But i have no image from the cam. Cam must be broken. So i have to wait another month to get this as spare part. Have also ordered another ESP board with an external antenna hoping to get better connection to the router.

The brownout detector error usually means that the ESP32 is not being powered properly. You can read more about this on our troubleshooting guide, bullet 8: https://randomnerdtutorials.com/esp32-troubleshooting-guide/

The ESP32-CAM should work fine being powered either with 3.3V through the 3.3V pin or 5V through the 5V pin. You’re probably not providing enough current.

Thank you very much for sharing. Using M5STACKcam I didn’t had image. After troubleshooting and comparing with other codes I changed setting for Y2_GPIO_NUM to 17. Now it works like a sharm
