Re: ESP32-Arduino: How to use SD library with VSPI

OK, proviso, I'm new to ESP32.... I don't believe you need to make any changes to the sd.* files Just use the code as per your link Connect sdCard to vspi pins: //SCLK = 18, MISO = 19, MOSI = 23, SS = 5 and connect your sensor to hspi pins: //SCLK = 14, MISO = 12, MOSI = 13, SS = 15 or, you can choo...

Re: WROVER with Arduino IDE

OK, I'm new to ESP32, so this may be wrong ! I believe you may need a new board configuration in the boards.txt file At the end of the compile, it gives a % used of program & data (RAM) The figure for data matches the board config line (WROVER board shown): esp32wrover.upload.maximum_data_size=32768...

Re: Calling function from inside ISR doesn't work

I think it's a bit more simple than that ...

for (int i; i < n; i++)
change to:
for (int i=0; i < n; i++)
might fix it
