Hi,
I started writing to SD cards using an arduino several version ago (version 21 I think), before the SD library was included as a standard library in version 22.
There used to be a file Sd2Card.h which allowed you to set the speed that data would be written to / read from the SD card.
SPI_FULL_SPEED
SPI_HALF_SPEED
SPI_QUARTER_SPEED
I’ve upgraded to version 1.0.1 and (up to now) haven’t had any problems writing to an SD card.
I’ve started experiencing problems and I thought I’d try to slowing the speed down in case there’s a problem with my hardware.
Can I change the speed now? If so, how? I can’t find any suitable variables to fiddle with!
thanks
