SPI pin number

[Tatsuya Anami]

Please help me !

(spi_maseter_config.h at line 29) #define SPI_PSELMOSI0 20u /**< SPI Master Out Slave In GPIO pin number. */

nRF51822 QFAA Package pin no.20 = P0.14 but SDK document write (Used SPI master pin configurations) .. MOSI0 (Pin 20, P2.4).

"pin number 20" what is this mean ??

Thanks

Hi,

It is GPIO P0.20, which is physically pin 28 on the QFN. Whenever you set a GPIO, it's mapped to P0.x, and its not related to the physical chip pin number.
