Hey guys,
I recently brought the CANBus Shield (DEV-13262). I’m trying to get the SD card reader to work, however I’m having problems.
To test, I’m using this code:
https://github.com/arduino-libraries/SD … rdInfo.ino
And setting the “chipSelect” variable to 9.
However, it reports that the SD card could not be initialised.
I’m working with a 8GB FAT32 micro sd card.
I’m gonna continue playing about an seeing what happens, have you guys got any ideas?

Heyah, thank you for the speedy reply!
Unfortuantly not, it prints…
Initializing SD card...Card failed, or not present
Then loads of…
error opening datalog.txt
I’ve tried on a Leonardo and Mega with the same issues.
I’ve got an Uno arriving tomorrow to test with. Could it be a pin issue?
Thanks
It’s pins. Leonardo and Mega do things differently with SPI and that’s how SD cards connect to Arduino.
The Uno should work just fine.

ah absolutely fantastic!
I’ve run some jumper wires over to the correct pins and now can write data
thank you very much both!
