I've followed the wiring diagram and used the provided example code from this link but failed to get the card to work.
I tried the following ways (with either Arduino IDE or platform IO on VisualCode):
1. Using the Micro SD card module
2. Wiring the Micro SD card directly to the ESP32 (via a SD card adapter)
None of them work and I always get the error when mounting the cards, the result is as follows:
Code: Select all
[W][sd_diskio.cpp:137] sdCommand(): no token received
[W][sd_diskio.cpp:137] sdCommand(): no token received

Code: Select all
[env:esp32doit-devkit-v1]
platform = espressif32_stage
board = esp32doit-devkit-v1
framework = arduino
monitor_baud = 115200
So what should I do now to solve this?
Many thanks
