Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

manual said SD Card I/O Pins
Alternatively, where no other devices share the SPI bus with the SD card it can be set up with:
OPTION SDCARD CS_pin, CLK_pin, MOSI_pin, MISO_pin
In this case the pins can be assigned completely flexibly and do not need to be capable of SPI operation but SD card performance will be better if valid SPI pins are chosen.
