Copy the following code to the Arduino IDE and upload it to your ESP32. Make sure you have the right board and COM port selected. You want the ESP32 to remember what was happening before losing power and return to the last state. This function takes the address of the byte you want to read as an argument. Or any other type of data that you need to have saved permanently. Before proceeding with this tutorial you should have the ESP32 add-on installed in your Arduino IDE. Follow one of the following tutorials to install the ESP32 on the Arduino IDE, if you haven’t already.

The images should be located inside a folder called data inside the sketch folder. In this article we’ve shown you different ways to display images in your ESP32/ESP8266 web servers. If you know any other suitable method, you can share it by writing a comment below.

Furthermore, the ESP32 is a dependable board, despite the fact that its firmware and attached peripherals can be flaky at times. I have been using ESP32 and ESP8266 Nodemcu modules for quite a long time in different IoT based projects. I have used these modules hundreds of projects for monitoring and controlling. In this article we will understand the differences between ESP32 and ESP8266 Nodemcu while also understanding the very important features of ESP32. ESP8266 and ESP32 are cheap Wi-Fi modules and are mostly used in the projects of internet of things. These modules come with GPIOs that support various protocols like SPI, I2C, UART, ADC, DAC, and PWM.

Specifications: ESP32 vs ESP8266

Continue reading to learn how the code works or skip to the “Demonstration” section. When the browser reads this HTML text, it will make a request on the /image_source. Continue reading this section to learn how the code works. In case you want to experiment with these images, you can download them here.


Using this library with the ESP32 is very similar to using it with the Arduino. So, if you’ve used the Arduino EEPROM before, this is not much different. The general answer is you have to accept that code compiled on ESP32 will be bigger. Either refactor code or board manufacturers need to use larger flash memory.


Just that I will want 15 locations with 2 pictures per location. The Text appiers, but the images did not, only Placeholders. In this section we show you how to display an image in a simple HTTP Web Server. Don’t forget to select the right board and COM port in the Tools menu.

So serial data SDA and serial clock SCL pin so through this GPIO 4 and 5 pins you can connect I2C devices to your esp8266 that means nodeMCU microcontroller. Now there are plenty of power pins so if you want to connect additional sockets you can have this 3.3 volt and almost four ground pins there on the board. So you can easily plug in this esp8266 kit does not MCU on a breadboard and connect to external circuits like LED switches motor display or any other peripheral devices. You can read in depth about the Nodemcu ESP8266 if you want to learn how to install the Nodemcu esp8266 board and other extreme basics.

So, if you’re a beginner, should you get started with the ESP32 or the ESP8266? At this point, we definitely recommend getting started with the ESP32 instead of the ESP8266. However, if you already have an ESP8266 board, you can get started with that board and then make the shift to the ESP32. In MicroPython, most Python scripts are compatible with both boards . This means that most of the time, you can use the same script for ESP32 and ESP8266.

ESPHome— ESPHome is a system to control your ESP8266/ESP32 by simple yet powerful configuration files and control them remotely through home automation systems. With this core, the ESP8266 CPU and its Wi-Fi components can be programmed like any other Arduino device. Hosting the Webserver was straight forward, but I found it difficult to display the pictures directly saved on the ESP32 . They key point was the ” make sure you listen for the /image request and serve the image accordingly.” as Sara stated. The main html might be initially loaded, but all referenced pictures are loaded thereafter via a GET request. You need to upload the favicon to the ESP8266 flash memory.

Home Automation using ESP8266 eBook and video course » Build IoT and home automation projects. I have built an automatic blinds controller and, using my android mobile, I can change the any of the values of the EEPROM in the ESP-Vroom-32 . This way I don’t have to take the controller off the wall to modify my programme and change the twilight/daylight values.

You can also of course generate aresp32 vs esp8266 memoryrary wave-forms on all output GPIO pins, up to a limit of all pins . Or use 16 channels for 16 pins, and drive remaining 20 using second core using software. I wouldn’t recommend using same core as the rest of the app and wifi stack is running, unless you don’t care too much about accuracy or frequency is relatively low.
