Persist data in Flash or SD card. Use GPIO’s; including inputs, outputs, Interrupts, Touch ADC etc. Use communications protocols with UART, I2C and SPI Use sleep and deep sleep to preserve power. Connect to Wi-Fi or set up your own Wi-Fi access point. Interact with Web API’s on ...

ESP32 Data Logging Temperature Sensor Readings to microSD card (Arduino IDE) ESP32/ESP8266: Publish Sensor Readings to Google Sheets via IFTTT ESP32-CAM Capture Photo and Save to MicroSD Card
Hello, I'm currently working on a project that involves data logging and saving on a microSD card using a Firebeetle using an ESP32 WROOM 32D. We currently have it working but I just realized a method of data extraction might not be possible. We wanted to extract the data via the ...
This project Incorporates Ethernet SPI for hosting local web page and SD card for data logging in sdspi mode. Moreover, I have enabled SPIRAM and use it for other dynamic memory allocation. I have 4 RTOS tasks running in the background, 2 for UART operations while other task is the data...
(Data Command) pin may be labelled AO or RS (Register Select) // // With some displays such as the ILI9341 the TFT CS pin can be connected to GND if no more // SPI devices (e.g. an SD Card) are connected, in this case comment out the #define TFT_CS // line below so it ...
I have a similar problem. On my project I'm writing very large data directly to an sd-card without filesystem. So I'm using sdmmc_write_sectors_dma(). Everything is ok until I make a wifi connection to my esp32-wroom32. Please check out, that I write 100MB to the sd-card in...
