Since #58, it ist possible to dynamically define the SD pins using: * `setxxx()` methods: `setDx`, `setCK`, `setCMD`, `setCKIN`, `setCDIR` or `setDxDIR`. * ` init()` or `begin()` Example of code: ```c++ card.setDx(PC8, PC9, PC10, PC11); while(!card.init(SD_DETECT_PIN)) { ``` As ` init()` or `begin()` called the setDx methods with default arguments the first call is simply not applied.
