I have the following question i`ve seen development  boards based on lpc1788 and all of them use SPI to access SD card when the MCU has sd card controller.I read that using four-bit SD bus is somehow closed licence and in order to use it i have to pay for i, my question is is that so and if yes can i use 1-bit SD bus for free(and where i can find code examples) or this  SD card controller is off limits (so to speak) for hobby electronics.
