#MicroPython: Tutorial and updated support for ESP32, M5Stack cameras
MicroPython | 5 min | 10721
Last week, I got some time to update the
lemariva/micropython-camera-driverto the actual versions of MicroPython, ESP-IDF, and the camera driver for the OV2640. MicroPython has changed since version 1.14 from
CMakewhich makes it easier to add support for different modules: in this case for the OV2640.
I will sum up the steps to compile MicroPython fr...
#MicroPython: OV2640 camera module extended (M5Camera, ESP32-CAM, etc.)

I've just upgraded the MicroPython camera module for ESP32. The OV2640 uses I2S and two months ago, I wrote/updated the I2S connector to support more boards (check the hardware and software section below).
This time with the help of @joerggollnick, the driver was extended to include the following camera settings:
vertical flip, and

#MicroPython: M5CAMERA timelapse video using MQTT
M5Stack, MicroPython | 4 min | 13436
The M5Camera is a camera unit based on ESP32 chip has an OV2640 and also includes a PSRAM. As you may already know, M5Stack is an open-source modular toolkit for IoT developments based on ESP32. There are four versions of this camera (see Fig. 1). I got the M5-Camera B and this is a tutorial to use the camera to generate timelapse videos. However, this module doesn't have a microSD slot. Therefore, the application will publish the photos on an MQTT Broker, so that an MQTT subscrib...

This tutorial updates the article: MicroPython: Taking photos with an ESP32-CAM, in which I described the steps to add support to the ESP32-CAM on MicroPython. In this tutorial, I've updated the driver, and more cameras/boards are now supported. I tested the driver on the ESP32-CAM and the M5CAMERA (model B). It should also work with every board that has an OV2640, and it can be extended to support the OV3660 (I didn't find any board with an ESP32 that uses this camera)....
