The Wi-Fi Manager allows you to connect the ESP32 board to different Access Points (networks) without hard-coding network credentials (SSID and password) and upload new code to your board. Your ESP will automatically join the last saved network or set up an Access Point that you can use ...
Using SPIFFS with ESP32, users can easily create, read and write files to/from the flash memory of the board. Due to limited number of write cycles of flash memory, it is not recommended to use the write functionality but it is still present. In short we can read, write, delete and ...
ESP32-WROOM-32是一款通用型Wi-Fi+BT+BLE MCU模组,功能强大,用途广泛,可以用于低功耗传感器网 络和要求极高的任务,例如语音编码、音频流和MP3解码等。 此款模组的核心是ESP32-D0WDQ6芯片*,具有可扩展、自适应的特点。两个CPU核可以被单独控制。时钟 ...
This example shows how to create a heatmap using wireless network signal strength measurements from an ESP32 development board. ThingSpeak™ helps you visualize your data by projecting measurements over an image or map. You do not need special hardware, but you need an image of the area and...
I'm using the Adafruit Qualia board with ESP32-S3. The board uses the PCA9554 io_expander to provide the SPI interface for a 40 pin LCD display (which uses the ST7701 driver). See schematics for reference: AdaFruit Qualia Board Connections to ESP32-S3.png To install the SPI panel, ...
