.. can we somehow bitbang the SPI (softspi) to be used with sdfat?
and would not be better then to define everything at one place like :
#define SS_ISNOT_CS
uint8_t const CS1_PIN = ;
uint8_t const SS_PIN = ;
uint8_t const MOSI_PIN = ;
uint8_t const MISO_PIN = ;
uint8_t const SCK_PIN = ;
uint8_t const SD_CHIP_SELECT_PIN = CS1_PIN;
when the SS is not being used as the CS (but must be set to output or the input pulled high), and the SS shall be then set properly inside the sdfat as well..
@crossroads - then you have to set SS to output when not used as the CS, and it may work..
