Re: ESP32S3 ADC to SD card logger - 1/6th of expected filesize - severe sampling rate mismatch? by MicroController » Sat Nov 30, 2024 5:55 am 1. Instead of fclose+fopen, try fsync 2. Retrieve the ADC data inside the ADC callback, then hand the data to the task for processing...
ESP32-WROVER based development board with 1.3 inch OLED (GPIO26-SDA, GPIO27-SCL) TP4056+DW06+LM39100 battery charging, 1 A charging/discharging, over-charging and over-discharging protection, LED indicator (red charging, green full), auto-download function, SD card slot, and a control ...

It also supports one SD card operating at 1.8V. 4.1.9 SDIO/SPI Slave Controller ESP32 integrates an SD device interface that conforms to the industry-standard SDIO Card Specification Version 2.0, and allows a host controller to access the SoC, using the SDIO bus interface and protocol. ESP32...
I have made the example of Esp32 to use a microSD card as a data storage medium, the idea is that of a datalogger. The example works perfectly fine, a file called hello.txt is created and then renamed to foo.txt. Now in my project I get the date using the rtc of the same Esp...
We can use this feature in many applications. For example, in the following projects, we used deep sleep in data logger applications where ESP32 remains in deep sleep mode to save power and wake up after some predefined time to take sensor measurements and save data to an SD card or Googl...

My project requires use of an SD card as it is a datalogger. I read in the ESP-WROVER-KIT getting started docs that SD and JTAG cannot be used together because of pin conflicts. Does this mean: 1) ESP-WROVER-KIT dev board cannot be used to develop code that involves SD card?
visitors this year:22,148 Costing less than £10 or $10, the ESP32-CAM board comes equipped with WiFi, a camera and a micro SD-card slot. It needs a little work to turn this ‘development board’ into a something you can use to keep an eye on your desk, your pet or whatever....
