Thus, the above git checkout line changes to: git checkout 5c88c5996dbde6208e3bec05abc21ff6cd822d26. The build may complete and the firmware may work but it is not guaranteedĬurrent git hash: 3eecd43b31a765aae0231ff9a227786bac31b9a2 The git hash of ESP IDF does not match the supported version Or go to the folder micropython-with-esp32-cam/ports/esp32 and type make without having a configured ESP-IDF, you'll get something like: Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity. At the moment of writing this article, the supported hash is the following: # the git hash of the currently supported ESP IDF versionĮSPIDF_SUPHASH := 5c88c5996dbde6208e3bec05abc21ff6cd822d26 This is now located here: micropython-with-esp32-cam/ports/esp32/Makefile. To do that, look for the Makefile in the MicroPython repository. You need to look for the right commit hash that is compatible with the current MicroPython version. This can be done typing the following: cd $MICROPYTHON To compile MicroPython for the ESP32-CAM, you need to setup the Espressif IoT Development Framework (ESP-IDF). Espressif IoT Development Framework (ESP-IDF) Just install python3-pip and then the packages using pip3 install pyserial pyparsing. Then, you don't need to install or activate any virtual environment. ![]() If you want to, you can also install pyserial and pyparsing as an user or root package. Then, put everything you need inside a folder: mkdir micropythonĪnd start a virtualenv inside that folder to install the dependencies: # linux On Windows, follow this article to install pip and install virtualenv with pip install virtualenv. To start with this, you need the following dependencies on your development machine: # linux However, if you want to, you can compile MicroPython yourself. You can deploy the firmware typing the following on a terminal: esptool.py -chip esp32 -port /dev/ttyUSB0 -baud 460800 write_flash -z 0x1000 esp32-cam-micropython.bin I uploaded the compiled firmware into the following repository: lemariva/uP圜am. MicroPython: Support for cameras: M5CAMERA, ESP32-CAM etc.Ĭheck out those, before you keep reading this article and instructions.MicroPython: M5CAMERA timelapse video using MQTT. ![]() There are two new articles about this topic: In the following table, you find the hardware and software that you will use for this tutorial: 1: Photo taken with the ESP32-CAM running MicroPython Thus, I write the steps again and added more information in this article.įig. ![]() The repository of tsaarni has a wiki with instructions, but some steps are not easily to understand and I had some issues with them. Moreover, I uploaded the compiled firmware, so that you can directly deploy MicroPython with camara support on the board and take photos. Additionally, I included a project with a webserver to take and see the photo. This tutorial is about compiling and deploying a version of MicroPython with support for I2S on the ESP32-CAM. However, last week I was searching between the ESP32 boards that I have, I found the board again, and I also found that tsaarni has written the driver for MicroPython. Thus, the only solution was to use the I2S interface, but I didn't have time to write the driver. There are many implementation for Arduino or directly using Espressif, but I wanted to use MicroPython. The board has an OV2640 without any chip (buffer) between the ESP32 and the camera. Last year, I bought an ESP32-CAM board from Banggood and I wanted to use it with MicroPython.
