Home Forums Sparkfun MP3 Shield Library Support Forum Host running less than 16MHz Reply To: Host running less than 16MHz


I have my Arduino running at 8 MHz. Encountering SPI communication problems:

Can’t access SD card. Do not reformat.

No card, wrong chip select pin, or SPI problem?

SD errorCode: 0X1,0X0


I tried dividing all the SPI_CLOCK_DIV’s in SFEMP3Sheild.cpp by two, but still getting problems.

I’m using a non-default SD-CS, and made sure to configure SD_SEL appropriately in SFEMP3ShieldConfig.h.


I’m wondering if there is somewhere else I need to set my non-default SD-SEL, or change CLOCK_DIV’s, to accommodate the 8 MHz host..hmm
