https://devzone.nordicsemi.com/f/nordic-q-a/52055/nrf52-gpioHi guy, I am new to nRF52, I read some example code and I see this: #define SPI1_CONFIG_SCK_PIN 2 #define SPI1_CONFIG_MOSI_PIN 30 #define SPI1_CONFIG_MISO_PIN 4 #define SPI1_CONFIG_IRQ_PRIORITY 6 #define SPI1_CONFIG_CS_PIN 3 I can&#39;t find in anyen-USTelligent Community 13Thu, 12 Sep 2019 08:10:34 GMThttps://devzone.nordicsemi.com/thread/209329?ContentTypeID=1Thu, 12 Sep 2019 08:10:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4b4d18cf-7dcb-4453-9bda-bf03b57ac07dawneil[quote userid="83303" url="~/f/nordic-q-a/52055/nrf52-gpio"]what document mention it?[/quote] <p>The <strong>Product Specification</strong>.</p> <p>eg, for nRF52832:&nbsp;</p> <p><a href="https://infocenter.nordicsemi.com/topic/struct_nrf52/struct/nrf52832_ps.html">https://infocenter.nordicsemi.com/topic/struct_nrf52/struct/nrf52832_ps.html</a></p> <p>specifically:</p> <p><a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/spim.html?cp=3_1_0_30_4#concept_v4x_5w2_wr">https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/spim.html?cp=3_1_0_30_4#concept_v4x_5w2_wr</a></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/209315?ContentTypeID=1Thu, 12 Sep 2019 07:29:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6148fea9-6f9b-479a-89e7-228cf653ae6bbjorn-spockeli<p>Hi nghia,&nbsp;</p> <p>the NRF52 Family has a pin crossbar, which means that all the serial and digital interfaces, i.e. UART, SPI, TWI, PWM, I2S, PDM etc can be routed to any of the Digital GPIOs. Please see the PSEL register for the individual peripheral for the allowed pin range.&nbsp;</p> <p>Best regards</p> <p>Bjørn</p><div style="clear:both;"></div>
