SD Card demo¶
Demo file : esp32_sdcard_demo.slx
This demo shows how to use the SD Card Block and String Processing Block for data logging to ESP32. In this demo the data will be taken from the ADC pins (GPIO36, GPIO39) with ADC Block and saved into the adc_data.csv with 0.5S per record.
What should be happening?¶
Once the sd card is inserted to the target module and executed the program, the data will be logged to the sd card. Wait about 10 seconds and remove the sd card and plug in to a Desktop or Laptop computer to view the data from adc_data.csv.
