Hi everyone,

I am having a weird issue with my ESP32cam and the SD.

I am able to take a picture and save it on the SD card. However, as soon as I setup the Wifi with WiFi.h and/or a scale with HX71_ADC.h. I get the following error from the SD library.

Is it a problem with libraries compatibility ? How can I solve this ?

Best regards,

Nicolas

If there is a shared gpio conflict then you will have to work around it.

Hi ! Thanks for your answer

I am not sure how to do so. Could you give me a hand please ? For some unknown reasons, the camera+wifi+sd works in 5V but not 3.3V
However, with the scale, it will not work no matter the voltage! Any clue why ?

Best regards,

Nicolas
