I have spent hours trying to get my ESP32 to talk to my SD card reader. You are the first contributor to mention "DO IT ESP32 DEV-KIT V1". Once I selected it... worked like a charm! Thank you!!!
Thank you for your very informative RUclips video. The instructions were easy to follow, and I now have have my SD card working on the ESP32 Dev Board.
hi, i have the same problem in serial monitor just say card mount failed. what have you done so you can solved that problem? i watch your video it seems you cut that process, can you help me? in serial monitor always say Card Mount Failed when i reset my esp32
Hello I have a esp 8266 and a micro SD that using the JINX program manages to record animations in the target, I want if you could help me which program I must load on the esp8266 so that he reads the microSD and sends me the animations to a matrix of 8x32 wide built with leds ws2812 (called neopixel) or if you can make a video regarding this topic
Great!; thank you. I needed to change the SPI pins, could not find anything on the net to use pins other than the default. I found if you edit the pins.h file for the "C:\Users\glenn\.platformio\packages\framework-arduinoespressif32\variants\esp32"; in my case. Commented out the default and added the pins I wanted to use. /* Commented out the default spi pins and added alturnaltives */ /* static const uint8_t SS = 5; static const uint8_t MOSI = 23; static const uint8_t MISO = 19; static const uint8_t SCK = 18; */ static const uint8_t SS = 25; static const uint8_t MOSI = 32; static const uint8_t MISO = 27; static const uint8_t SCK = 4; One could make a special variant; however, I never tried this.
Hi, thanks a lot for the code. Do you know how to detect when the SD was removed o extracted and when it was put on again? for example, it is working normally and it is on, but someone wants to extract SD and does not turn off the device and then put again, so dont work well, but if i detect that was extracted i can do somethink. do you know somethink like that?
you can create log file on sd card and write time after some interval . again read log file check current time and saved time the interval should be same if not sd card was intrupted
Hola yo tengo un esp 8266 y una micro SD que usando el programa JINX logre grabar en la targetas animaciones,yo quiero si usted me podría ayudar que programa debo cargar en el esp8266 para que el me lea la microSD y me envíe las animaciones a una matrix de 8x32 de ancho construida con leds ws2812(llamados neopixel)o si usted puede hacer un video con respecto a este tema

10 times OK! in a sec .
it's a new skill that you have unlocked bro !
Thanks! this worked for my Inland ESP32 from micro center
if any one get an error. try changing the 3.3v pin to vin pin. it worked for me.
The SD card module has onboard DC dc converter.which converts 5v to 3.3v. So yes you should connect it to 5v.
thanks you! i spend hours trying to solve it and it worked!

How did you lift the Card mount failed error report? I am having the same problem and it doesn't seem to work.

add more voltage, use potentiometer to vary it
@@drycell476 Thank you for that broo!!!
The 3.3V output on te ESP32 is connected to the 5 to 3.3V regulator input. This is wrong.
Yes, it will get failed messages into serial monitor, it can’t activate CS pin
what should be the pin connection then?
@@ifjsnayarn0418 Change from 3V3 to Vin Pin and it will work.
@@sa-ej4sq thanks
@@sa-ej4sq it didn’t work
May I know if two esp32 can be connected to one sd card? If so, how to connect it? Please help me know about it.
It is possible but not simultaneously.

weird symbols only shows up at my serial monitor, i dont know what to do.

Hi my friend, are you available to help me to setup Arduino code into my ESP32? I will be happy to pay you a coffee.
Is it possible to setup linux/windows in ESP32 like rasberry pi??
No it's not possible
Use pi zero w
do u know why i can't save all my sensor data on microSD using esp32? i have put the program on void loop but i cant save all data
You mean you are able to save data partially?
@@techacademy9787 yes
Increase delay

But what are you doing to resolve the failed problem?
make sure sd module vcc is connected to 5v

m sale que no contiene una libreria valida
So what is the max size for sdcard ???
16 GB
how to connect the speaker with sd card module?
Hi, nice project. I am not lucky and got " Card Mount Failed " error, any solution please.
Connect card VCC to 5v
SD card module has 5v to 3.3v ldo
....
Ok
