I think my wiring is incorrect.
Maybe you can help me with wiring
Nodemcu SPI pins:-
D5- SCK
D6- MISO
D7- MOSI
D8 - CS
Yes, i have wiring like this.
But this message is shown:
‘dataFile’ was not declared in this scope.
When i delete… //dataFile.print(" | ");…uploading is done but this message is shown:
Leaving…
Hard resetting via RST pi…
And nothing is happening.
i dont see datafile anywhere in this code.
